Customizing Struts Displaytag table properties - html

I have knowledge on how to customize the display data using Struts2 displaytag:table and decorator.
But I need to customize the table columns (tr style)
public String getWorkFlow() {
WorkOrderDO currentWorkOrder = (WorkOrderDO) getCurrentRowObject();
String output = null;
if (currentWorkOrder.getChildId() == 0) {
if (!currentWorkOrder.isWorkFlowRetrieved()) {
output = "<input type = 'submit' value = 'Work Flow' id=" + currentWorkOrder.getMoveWorkOrderId() + " onclick = 'changeWorkOrder(this);return false;'/>";
} else {
output = "<input type = 'submit' value = 'Work Flow' id=" + currentWorkOrder.getMoveWorkOrderId() + " onclick = 'changeWorkOrder(this);return false;' disabled/>";
}
}
return output;
}
from above method in decorator class, we can customize the data look and feel.
But my question is, if currentWorkOrder.isWorkFlowRetrieved() == true, I want to highlight the entire column (tr) in the table in the display page with style property
Any idea?

you can do this by using style attribute in the display:column tag
for eg
I hope this works for you.

Custom row/checkbox template for Kendo UI grid

I am trying to create a custom row template for a Kendo UI grid that includes the checkbox functionality. I have the grid created like this:
#(Html.Kendo().Grid(Model.Users)
.Name("usersGrid")
.Columns(columns =>
{
columns.Select().Width(50);
columns.Bound(c => c.UserName);
})
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false))
.ClientRowTemplate(UsersClientTemplate))
With a function to generate the row template like this:
Func<Grid<User>, string> UsersClientTemplate = (grid) =>
{
var id = Guid.NewGuid();
return #"<tr data-uid='#:uid#' role='row'>" +
"<td role='gridcell'>" +
$"<input class='k-checkbox' data-role='checkbox' type='checkbox' id={id}>" +
$"<label class='k-checkbox-label k-no-text' for={id}>​</label>" +
"</td>" +
"<td role='gridcell'>" +
"<a href='/users/details/#:data.Id#'>#:data.UserName#</a>" +
"</td>" +
"</tr>";
};
The problem is I can't figure out how to generate the unique ids for each row's template. If I don't include the id attribute on the checkbox input element and the for attribute on the checkbox label element, the checkbox/row selection doesn't work. But with the function I have above, the same id is generated for every row template and then the checkbox/row selection only works for the first row, obviously.
What is a better way to do this?
Templates are generated when the grid is built so as you have seen the id is always the same. What you want is to databind so kendo replaces the id with each record. I use my entity key with a prefix like "cb_" for checkbox:
$"<input class='k-checkbox' data-role='checkbox' type='checkbox' id='cb_#:uid#'>" +
$"<label class='k-checkbox-label k-no-text' for='cb_#:uid#'>​</label>" +

Customize html output for a field's droplist options

I have a field called icon, which is a droplist sourced from folder in the content tree. I would like the list to not just show the text value(shown in the screen shot) but also to utilize an icon font and display what the actual icon would look like. Basically customizing the content editor's droplist for this field from:
<option value="gears">gears</option>
to
<option value="gears">gears <span class="my-icon-font-gears"></span></option>
Is there any documentation on how to modify the outputted html for a droplist, and to modify the content editor page to load another link, in this case a font-file.
I created a module on the marketplace that does something similar. You can have a look here. There is some documentation on there explaining how to use it.
The code is also on Git if you want to have a look.
Suggest you use the Droplink field type instead of the Droplist, since the value is stored by GUID and this will lead to less longer term problems if the link item is renamed or moved. In any case you need a custom field, inherit from Sitecore.Shell.Applications.ContentEditor.LookupEx (which is the DropLink field type) and override the DoRender() method with the custom markup you require.
It's not possible to embed a span tag since the option tag cannot contain other tags as it is invalid HTML. Adding it will cause the browser to strip it out. You can however set the class on the option itself and style that.
`<option value="gears" style="my-icon-font-gears">gears</option>`
Here is some sample code to achieve the field.
using System;
using System.Web.UI;
using Sitecore;
using Sitecore.Data.Items;
using Sitecore.Diagnostics;
using Sitecore.Globalization;
namespace MyProject.CMS.Custom.Controls
{
public class StyledLookupEx : Sitecore.Shell.Applications.ContentEditor.LookupEx
{
private string _styleClassField;
private string StyleClassField
{
get
{
if (String.IsNullOrEmpty(_styleClassField))
_styleClassField = StringUtil.ExtractParameter("StyleClassField", this.Source).Trim();
return _styleClassField;
}
}
// This method is copied pasted from the base class apart from thhe single lined marked below
protected override void DoRender(HtmlTextWriter output)
{
Assert.ArgumentNotNull(output, "output");
Item[] items = this.GetItems(Sitecore.Context.ContentDatabase.GetItem(this.ItemID, Language.Parse(this.ItemLanguage)));
output.Write("<select" + this.GetControlAttributes() + ">");
output.Write("<option value=\"\"></option>");
bool flag1 = false;
foreach (Item obj in items)
{
string itemHeader = this.GetItemHeader(obj);
bool flag2 = this.IsSelected(obj);
if (flag2)
flag1 = true;
/* Option markup modified with class added */
output.Write("<option value=\"" + this.GetItemValue(obj) + "\"" + (flag2 ? " selected=\"selected\"" : string.Empty) + " class=\"" + obj[StyleClassField] + "\" >" + itemHeader + "</option>");
}
bool flag3 = !string.IsNullOrEmpty(this.Value) && !flag1;
if (flag3)
{
output.Write("<optgroup label=\"" + Translate.Text("Value not in the selection list.") + "\">");
output.Write("<option value=\"" + this.Value + "\" selected=\"selected\">" + this.Value + "</option>");
output.Write("</optgroup>");
}
output.Write("</select>");
if (!flag3)
return;
output.Write("<div style=\"color:#999999;padding:2px 0px 0px 0px\">{0}</div>", Translate.Text("The field contains a value that is not in the selection list."));
}
}
}
This field adds a custom properties to allow you to specify the linked field to use for the style class. The assumption is that you have another single line text field on the linked item to specify the CSS class.
Usage: Set the source property of the field in the following format:
Datasource={path-or-guid-to-options}&StyleClassField={fieldname}
e.g. Datasource=/sitecore/content/lookup/iconfonts&StyleClassField=IconClassName
To use this new field compile the above code in to project, switch over to the core database and then create a new field type – you can duplicate the existing Droplink field located in /sitecore/system/Field types/Link Types/Droplink. Delete the existing Control field and instead set the ASSEMBLY and CLASS fields to point to your implementation.
You also need to load a custom CSS stylesheet with the style defintions into the Content Editor, which you can achieve that by following this blog post.

Adding attribute to checkbox list at runtime

So I have some code that dynamically creates an ASP.NET form based on an XML input file. I'm trying to add attributes to the controls at run time and I'm having some weird issues with list items.
My Server Side Code looks something like this:
Me.radioButtonList = New RadioButtonList()
Me.dropDownList = New DropDownList()
Me.listControl = Nothing
If controlType = "dropdown" Then
Me.listControl = Me.dropDownList
Else
Me.listControl = Me.radioButtonList
End If
For Each ansElement As Answer In strAnswers
Dim newListItem = New ListItem(ansElement.AnswerText, ansElement.AnswerText)
If ansElement.ActionID IsNot Nothing AndAlso ansElement.ActionID <> "" Then
newListItem.Attributes.Add("actionID", ansElement.ActionID)
End If
Me.listControl.Items.Add(newListItem)
Next
Me.listControl.ID = controlID
Me.Controls.Add(Me.listControl)
The problem is when I run the code and the page is render the attributes are being added to the proceeding span tag of the control not the input item itself. So the rendered HTML ends up looking like this.
<span actionID="1">
<input id="lst_dynamic_MedIllnesses_0" name="ctl00$MainContentPlaceHolder$FormGenerator1$lst_dynamic_MedIllnesses$lst_dynamic_MedIllnesses_0" value="None" type="checkbox">
<label for="lst_dynamic_MedIllnesses_0">None</label>
</span>
What do I have to do to get the actionID attribute to be added to the actual input control and not the span tag?
Thanks!
I suppose you are talking about RadioButtonList. The problem with it is that it uses RadioButton control, and it has 3 attributes properties - Attributes, InputAttributes and LabelAttributes. Each of them is used for specific html element.
The problem with RadioButtonList, is that it uses just Attributes property, and doesn't use InputAttributes. Here is code of RadioButtonList.RenderItem method:
protected virtual void RenderItem(ListItemType itemType, int repeatIndex, RepeatInfo repeatInfo, HtmlTextWriter writer)
{
if (repeatIndex == 0)
{
this._cachedIsEnabled = this.IsEnabled;
this._cachedRegisterEnabled = this.Page != null && !this.SaveSelectedIndicesViewState;
}
RadioButton controlToRepeat = this.ControlToRepeat;
int index1 = repeatIndex + this._offset;
ListItem listItem = this.Items[index1];
controlToRepeat.Attributes.Clear();
if (listItem.HasAttributes)
{
foreach (string index2 in (IEnumerable) listItem.Attributes.Keys)
controlToRepeat.Attributes[index2] = listItem.Attributes[index2];
}
if (!string.IsNullOrEmpty(controlToRepeat.CssClass))
controlToRepeat.CssClass = "";
ListControl.SetControlToRepeatID((Control) this, (Control) controlToRepeat, index1);
controlToRepeat.Text = listItem.Text;
controlToRepeat.Attributes["value"] = listItem.Value;
controlToRepeat.Checked = listItem.Selected;
controlToRepeat.Enabled = this._cachedIsEnabled && listItem.Enabled;
controlToRepeat.TextAlign = this.TextAlign;
controlToRepeat.RenderControl(writer);
if (!controlToRepeat.Enabled || !this._cachedRegisterEnabled || this.Page == null)
return;
this.Page.RegisterEnabledControl((Control) controlToRepeat);
}
controlToRepeat is that RadioButton, and it specifies only Attributes property and ignores InputAttributes.
I can suggest way to fix it - you can create new class that inherits RadioButtonList, and use it instead of default. Here is code of that class:
public class MyRadioButtonList : RadioButtonList
{
private bool isFirstItem = true;
protected override void RenderItem(ListItemType itemType, int repeatIndex, RepeatInfo repeatInfo, HtmlTextWriter writer)
{
if (isFirstItem)
{
// this.ControlToRepeat will be created during this first call, and then it will be placed into Controls[0], so we can get it from here and update for each item.
var writerStub = new HtmlTextWriter(new StringWriter());
base.RenderItem(itemType, repeatIndex, repeatInfo, writerStub);
isFirstItem = false;
}
var radioButton = this.Controls[0] as RadioButton;
radioButton.InputAttributes.Clear();
var item = Items[repeatIndex];
foreach (string attribute in item.Attributes.Keys)
{
radioButton.InputAttributes.Add(attribute, item.Attributes[attribute]);
}
// if you want to clear attributes for top element, in that case it's a span, then you need to call
item.Attributes.Clear();
base.RenderItem(itemType, repeatIndex, repeatInfo, writer);
}
}
A bit of description - it has isFirstItem property, as RadioButton control that used by it is created in runtime in the first access, so we need to call RenderItem before we can update InputAttrubutes property. So we call it once and send some stub HtmlTextWriter, so it won't be displayed twice. And then after that we just get this control as Controls[0], and for each ListItem we update InputAttributes values.
PS. Sorry, I didn't use VB.Net so control is written in C#

How can I write and read bool values into/from cookies?

I want to save the state of checkboxes in an html form on submit to cookies, and then enable/disable other parts of my site based on those cookie values.
I've started out with code like this:
HTML:
<form method="POST">
<fieldset>
<legend>(Not really) Opt In or Out</legend>
<input type="checkbox" id="selectTwitter" name="selectTwitter" >I'm Twitterpated!</input><br />
. . .
Razor:
#{
var twitterSelected = false;
. . .
if (IsPost)
{
twitterSelected = Request["selectTwitter"].AsBool();
Response.Cookies["TwitterSelected"].Value = twitterSelected.ToString(); // Doesn't seem to accept saving boolean vals - saved as "false" or "true"?
Response.Cookies["TwitterSelected"].Expires = DateTime.Now.AddYears(1);
. . .
...but am stuck on how to check or uncheck the checkboxes based on possibly existing cookie vals:
if (Request.Cookies["selectTwitter"] != null)
{
// what now?
}
Cookies are strings. You'll need to convert the cookie value to the type you want. The boolean values are being saved as true or false because that's the string representation of a boolean.
var selectTwitterCookie = Request.Cookies["selectTwitter"];
bool selectTwitter = false;
if(selectTwitterCookie != null)
{
bool.TryParse(selectTwitterCookie, out selectTwitter);
}
Alternatively, you could use Convert.ToBoolean(selectTwitterCookie).

Html form, radio button and Servlet

I've writen a servlet that builds an html page showing the content of a database. The code is:
Statement st = (Statement) conexion.createStatement();
ResultSet rs = st.executeQuery("select * from audiolist" );
while (rs.next())
{
contador++;
out.println("<tr>");
String k = rs.getString("Tittle");
String l = rs.getString("Autor");
String m = rs.getString("Album");
out.println("<td>"+"<input type=\"radio\" name=\"titulo<%="+contador+"%>\"value=\""+k+"\">");
out.println("<td>" + k + "</td>");
out.println("<td>" + l + "</td>");
out.println("<td>" + m + "</td>");
out.println("</tr>");
}
out.println("</table></center>");
out.println("<tr><td colspan=2><input type=submit></td></tr>");
out.println("</form>");
I've added a radio button to each row. With this code I get to show in the browser a table with the content of the database. When I click on submit I want send to another servlet the vale 'k' for the row selected. I'm having a hard time with this. I think I'm sending the value incorrectly. In the second servlet, is it enough to use getParameter() in order to get the info?
Thanks!
In the second servlet you can use:
String value = request.getParameter("tituloX");
to read the value. You need to know the name of the parameter to do. If this is not known, you can try to enumerate the parameters:
for ( Enumeration e = request.getParameterNames(); e.hasMoreElements();) {
String param = (String) e.nextElement();
String value = request.getParameter(param );
}
This only works for parameters with a single value.
Is this line correct?
out.println("<td>"+"<input type=\"radio\" name=\"titulo<%="+contador+"%>\"value=\""+k+"\">");
