In windows phone 8.I have to select single item from list .I can use toolkit list picker .But the issue is default value is selected as first one. It should be empty i.e by default no item is selected
simply add a item named "please select" and set it as default. If the user doesn't select a item you can check if this item is stil selected and prevent the user from the next step.
you can think of the listpicker like a dropdown menu in html. there is no way a dropdown box is in a state where no item is selected.

Good day,
I have one form call Check Router. In that subform I have one text box (TxtPartNo), one list box (LstPartNo) and one subform (CheckRouteSubform).
These are the roles of those function
TxtPartNo --> User will key in the Item Description that they wanted to check its Route.After that,they will click add button.
LstPartNo --> its row source type is value list. After the user click Add Button, the Item Description that they key in will insert in this list box. Then they will select all data list and click on check button.
CheckRouteSubform --> This subform is based on CheckRouteQuery. After check button is click, I wanted it to be filter based on that Item Description. If it contain but not exactly equal that part_No, it will show in this subform.
example : user key in = FCLF-8531
subform will show data that contain FCLF-8531-RX, FLCF-8531-AX.
here I attached the picture of the form
Below are the picture of query :
As you can see i create criteria of Item Description based on the listbox.
and in check button I used this code:
Private Sub CmdCheckRoute_Click()
Dim i As Integer
For i = 0 To Forms!CheckRoute!LstPartNo.ListCount - 1
Forms!CheckRoute!LstPartNo.Selected(i) = True
Next i
DoCmd.RunSQL "CheckRouteQuery"
End Sub
However, it does not want to show what I need. :( Help me please.

Hey guys I have a many to many checkbox where a user can select many cities. I have a dropdown list above for selected state. I want to bring back only the regions that belong to that state that is selected.
thanks
Have you considered using a List and Details Screen instead of a dropdown list? You would just need to add both the states and cities tables to the advanced data section.
However, if you really need to use a drop down box, it is very complex but can be done.
You will need to begin a new search screen and lay it out as follows:
Create a group to start. You will need to 'add data item...' and choose Property, StateTable. Name this 'State' and add it to the group.
Create a second group. Again 'add data item...' Choose Query, CitiesTable (All). Name this StateCities. In the side panel, click 'edit query' next to StateCities and set it up as follows:
Return to your design screen by clicking the 'back to -screenname-' just above the filter statement. You should now see three bold items in the sidebar to the left. The first will be your StateTable, the second will be your StateCites query and the third will be your single State query.
Click the dropdown button for the StateCities query and you will see the query parameters at the bottom. You have a parameter called 'id'
Click on the Id parameter from the sidebar and change the parameter binding property (shown on the right hand side bar) to State.Id. If everything has been done correctly, this should hook up to your state query id field.
Once this is hooked up, you should be able to save your screen and run your program with the desired results!
I am using Winform and MySQL in my project.
When I try to get the ComboBox Vales in Different Method I saw the ComboBox Selected Text Propriety is empty.
Why it is empty?.
And Please say the Difference b/w ComboBox Selected Item and Selected text?.
SelectedItem is the combobox item which is selected by the user, whereas the SelectedText property contains the possible selected part of the item text.
In your example "CITY" is the string representation of the selected item. If the user only selects "IT" in the text area of the combobox (if possible) this is the value of SelectedText.
I would like to set the visibility of columns based upon the value selected in a parameter.
The problem is I do not want a specific parameter to do this (i.e Hide column X True/False)
My report has several different "departments" who are only interested in certain columns.
What would be the syntax for example to hide the "Sales" column when the "Customer Care" parameter is set?
you can do these works step by step:
1- press right click of your mouse in your favorite column
2- select column visibility
3- from opened window select "Show or hide based on an expression" radio button
4- set an expression for hidden state. for example:
=IIF(Parameters!CustomerCare.Value <> "favorite value", true,false)
