I have windows phone list picker Control in my code I bind the items from c#.i.e, items comes from services .I have to keep "select all" item .so that i can select all the items at once.I added "select all" .On checking the "Select All" check box .I could not get any event to execute the code so that all check boxes are checked and UI get reflected
Thanks in advance
Try this code
private void SelectAll(object sender, RoutedEventArgs e)
{
yourlistbox.SelectAll();
}
For more information check out the documentation in msdn http://msdn.microsoft.com/en-us/library/system.windows.controls.listbox.selectall%28v=vs.110%29.aspx
Im not sure if this the right way, But this works
List<object> arr = new List<object>((((System.Collections.Generic.Dictionary<string, string>)(s))).Values);
for (int k = 0; k < data.Length; k++)
{
object selectitem = arr[k];
items.Add(selectitem);
}
yourlistbox.SelectedItems = items;
This is how i made it work in my case so the way is to create a list object containing all elements from your data source and assigning to to selected items.
I think this can be done with LongListMultiSelector

I have a QTableView in my project, in which several columns display data that includes a hyperlink. I use a delegate class for these to set it up so that when the cell in the column is clicked, it opens the linked page in the browser. This works great... when it's only one value being linked to one page. For example, I may have a list of search values for mysite.com where the columns have values A, B, C, etc.. If the user clicks on the cell in this column with A, it will open a hyperlink for mysite.com/A (again, this part works fine). However, I now need to add a column that may have something like "A,B", where it needs to support links to search for A AND B in the same cell depending on which they click. I've been searching around online for a while now and it seems like this probably can't be done with a delegate. I have a line in a QTextBrowser elsewhere in my code where I can do this via HTML, like this:
QString toShow;
for(int i = 0; i < searchValueList.size(); i++)
{
toShow.append("`<a href=\"www.mysite.com/" + searchValueList.at(i) + "\"`>" +
searchValueList.at(i) + "`</a`>";
}
However I can't find any way to set the cells in a QTableView to recognize HTML formatting or Rich Text, and alas I'm not even sure that's possible. Is there any way at all to do what I'm trying to accomplish?
You can create a custom QItemDelegate for the specific column in which you can display rich text. The delegate could be like :
class RichTextDelegate: public QItemDelegate
{
public:
RichTextDelegate(QObject *parent = 0);
void paint( QPainter *painter,
const QStyleOptionViewItem &option,
const QModelIndex &index ) const;
};
RichTextDelegate::RichTextDelegate(QObject *parent):QItemDelegate(parent)
{
}
void RichTextDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
if( option.state & QStyle::State_Selected )
painter->fillRect( option.rect, option.palette.highlight() );
painter->save();
QTextDocument document;
document.setTextWidth(option.rect.width());
QVariant value = index.data(Qt::DisplayRole);
if (value.isValid() && !value.isNull())
{
document.setHtml(value.toString());
painter->translate(option.rect.topLeft());
document.drawContents(painter);
}
painter->restore();
}
You should set the item delegate for the specific column :
ui->tableView->setItemDelegateForColumn(colIndex, new RichTextDelegate(ui->tableView));
Now if you set the model text for the specific column in a row to a rich text, it will be shown properly :
model->item(rowIndex, colIndex)->setText(someRichText);
i have a class (TheList.as). in which i have an array "Data" and it has a couple of values. Then i have a loop through which i am creating a scrollable list which uses the values from "Data" array. [I am trying make a unit converter]
Then i have another class "Units.as". In that class i have created three instances of "TheList". A main list ("myList"), and to sublists "ListFrom" and "ListTo". They are using values from "Data" array. Now i have text field whose value changes to whatever item is clicked. When i click "Angle" in the main list, i want the sublists to get populated with ("Degree", "Radian" etc)..
Here is what i tried
if(myList._TextLabel.text == "Angle")
{
ListFrom.Data = ["Degree", "Radian"];
}
But nothing happens, i do not get any error either. When i do this in an "ENTER_FRAME" event and trace (ListFrom.Data), i can see that the values change, but they do not get assigned to the list items in the list. I would really appreciate the help. Thanks!
Here are complete Classes for understanding the situation better(the code is pretty messy, as i am a newbie to OOP)
TheList.as: http://pastebin.com/FLy5QV9i
Units.as : http://pastebin.com/z2CcHZzC
where you call ListFrom.Data = ["Degree","Radian"], make sure when the data changed, the renders in the ListFrom have been set new data. for example, you may use MyRender in ListFrom for show, you should debug in the set data method in MyRender.
you should call the code below after you call ListFrom.Data = ["Degree","Radian"];
for (var i:int = 0; i < Data.legnth;i++) {
var render:MyRender = ListFrom[i] as MyRender;
if (render) {
render.data = Data[i];
} else {
var render:MyRender = new MyRender();
render.data = Data[i];
ListFrom.addChild(render);
}
}
You can use event listeners, singleton classes or reference one class to another, depending on the style you want. All are equally valid and fast / efficient.
I've a Tree with checkbox with dataprovider as an xmlList. Now I need to get the item renderer of the list item without click on item and by search the from outside.
protected function btnSearch_clickHandler():void
{
var searchString:String = txtInputSearch.text;
if(searchString != "")
{
StyleItemsArray.removeAll();
var conaintList:XMLList = (treeSource.node.(#label.search(searchString) > -1) as XMLList);
for each(var xmlItem:XML in conaintList)
{
// trigger the checkbox click event here
}
}
}
Sorry for delayed:
I tried the solution given but it seems datagroup is used in Flex 4 but I'm still in flex 3 version.
I tried couple of other way (e.g. itemToItemRenderer())but no luck.
Could someone please help me out?
you can retrieve all item-render of list by just using for getElementAt.
for(var i:int=0; i < youListVariable.dataProvider.length; i++)
{
var render:CustomFieldRenderer = youListVariable.dataGroup.getElementAt(i) as CustomFieldRenderer
//put Your comparison condition and if condition matched then break
}
CustomFieldRenderer is your itemRender.
youListVariable is your list's id i.e. list's variable.
I'm trying to create a flash application that will keep track of user generated values. The app should basically allow the user to input the name of the item and it's cost. The total costs should then be added up to show a total value to the user. I can probably figure out how to add the values together, but I'm not really sure how to allow the user to create a list and then allow the user to save it. Can anyone point me towards a tutorial or point me in the right direction?
I am using variables to add user inputed numbers to come up with a total. The first problem is that actionscript 3.0 does not allow variables for texts. I just converted it to 2.0 to fix this. The second problem, is when I test the app and put in my values and click submit, I get NaN in the total values field. Is there a reason why it wouldn't add the values?
Here is the code I used for the submit button:
on (release) {
total = Number(rent) + Number(food) + Number(travel) + Number(entertainment) + Number(bills);
}
Am I missing anything?
Can I give the input text instance names and then give them variables? How are some ways to go about this?
Thanks for the help!
Have an object array, say for example
var stack:Array = new Array();
Then push the item name and it's cost to that array when user inputs, like
stack.push({item:AAA, cost:xx});
So that you can generate the list whenever you want with that array.
You have to see how this works in code. A list in actionscript could be stored inside an array, vector, dictionary or even an Object.
Var myList:Array = [];
myList.push({name: "item 1", cost: 5 });
myList.push({name: "item 2", cost: 7.5 });
If you want to grab the 'product' of "item 1" from the list, you have to create a function for that, lets call it getProductByName
function getProductByName(name:String):Object
{
for each(var product:Object in myList)
{
if (product.name === name) return product;
}
return null; // no match found
}
You can call that function like this:
var product = getProductByName("item 1");
trace(product.cost); // 5
And you can alter the product, so lets make it more expensive
product.cost += 1;
trace(product.cost); // 6
Have fun! If you are using classes, you would create one for the product, with public name and cost, and in that case you'de better use a vector, to ensure working with the right type.
This is what fixed the issue for me in action script 3.0:
myButton.addEventListener(MouseEvent.CLICK, addThem);
function addThem(e:MouseEvent)
{
totalField.text = String ( Number(field1.text) + Number(field2.text) + ....);
}
I also had to name the instances appropriately.
i've got an issue with Jtable and my dataModel.
My table model extends AbstracttableModel, the datas are stored in a Vector.
I'have a function witch is suppose to remove one or more row.
These rows are not necessarily contiguous because my jtable set a selectionMode as this:
jTable.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
The function to remove row (one by one):
public void removeMessageRow(Integer p_idMessage) {
Enumeration<MlMessage> alldatas = vData.elements();
while (alldatas.hasMoreElements()) {
MlMessage m = alldatas.nextElement();
if (m.getIdMessage() == p_idMessage) {
int idx = vData.indexOf(m);
boolean result = vData.remove(m);
// fireTableDataChanged();
// fireTableRowsDeleted(idx, idx);
fireTableStructureChanged();
return;
}
}
When i launch the function, i execute the loop without problem, in step-by-step mode, i can see the vData object updated and if i execute this only one time there is no probleme with the GUI. The problem appear when i select more than one row.
For example, i selected row number 0 and number 1 in my table and i lauch the function removeMessageRow, at the first execution, the vDataObject is correctly updated (all the datas are shiffted and the last elements of this vector is set to null by the call to vData.remove(m).
So in my case, i expect that at the second execution, the object to find should be at position 0 but it's at position 1 as the vData Object as never been updated.
Does anybody have an idea about that?
I've tried many on fire... stuff but no one semms to execute immediatly.
Thanks for any help by advance and sorry for my Shakespeare's language.
Add a method in your model taking a collection of indices to remove (Set<Integer>, or int[]), sort this collection, iterate backwards in this collection, and remove the elements in the list of objects of your model:
public void removeRows(int[] indices) {
Arrays.sort(indices);
for (int i = indices.length - 1; i >= 0; i--) {
this.data.remove(indices[i]);
fireTableRowsDeleted(indices[i], indices[i]);
}
}
int[] selectedRow = tblUsuarios.getSelectedRows();
int del=1;
for(int j=0; j<selectedRow.length; j++){
modTabla.removeRow(selectedRow[j]);
if(j<selectedRow.length-1){
selectedRow[j+1] = selectedRow[j+1]-del;
del = del+1;
}
}
//modTabla = defaultTableModel
//tblUsuarios = jtable
