ASP.NET

I have a page with 2  panels

The first panel loads data in a  Radgrid(TELERIK control) with 4 fields(id,name,city,state)  and one button (SELECT).When user clicks SELECT  that particular row is highlighted.
Panel 2 has ID and NAME text boxes which should be read only.
Now my question Is I want the values of the ID,Name(from panel1) for the highlighted row to be sent to the ID,Name in panel2 and make panel1 visible=false.

How can I do this??I appreciate if I can get some ideas....

Below is the sample code.

'Loads the grid with data
    Protected Sub BtnSearchDealers_Click(ByVal sender As Object, ByVal e As EventArgs) Handles BtnSearchDealers.Click
 
        Dim dealerResults As BusinessEntity() = CrmHelper.GetAccounts(Me.TxtDealerNumber.Text.Trim(), Me.TxtZipCode.Text.Trim(), CType(ViewState("SearchAccountType"), AccountType), Me.TxtDealerName.Text.Trim())
 
        ' TODO: Store properly
        Session("test_dset") = dealerResults
 
        Me.RGSearchResults.DataSource = dealerResults
        Me.RGSearchResults.DataBind()
 
    End Sub
'Select row is highlighted
    Protected Sub RGSearchresults_ItemCommand(ByVal sender As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles RGSearchResults.ItemCommand
 
        Select Case e.CommandName.ToLower()
            Case "select"
                RaiseEvent DealerSelected(sender, e.CommandArgument)
        End Select
 
    End Sub

Not enough information. Lets see your ASPX code where the panels are, and any other relevant code. Unless something made it very messy I would likely use JavaScript to handle this issue.

I'm not familiar with the Radgrid control, but something like below should work.

If you want it to be faster (i.e. no page reload) surround both panels in an ASP.Net Ajax UpdatePanel


    Protected Sub RGSearchresults_ItemCommand(ByVal sender As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles RGSearchResults.ItemCommand
 
        Select Case e.CommandName.ToLower()
            Case "select"
                txtID.Text = {Get the selected ID here}
                txtName.Text = {Get the selected Name here}
                panel1.Visible = false
                panel2.Visible = true
        End Select
 
    End Sub

Sorry busy week. The user control really makes this a complex issue. Glad I asked to see what was going on there. I really don't have time to make a full scale example of this. It looks like you are on the right track already. Can't just tell you...here are 5 lines of code that will sove this for you, sorry.

You need to:
1) Get the data you want (id and name?) in the itemcommand
2) Create a commandeventhandler on the usercontrol
3) call the commandevent passing it the data you want to go to the 2nd panel
4) create event to listen on the main page
5) update your panel1/panel2 visibility and the controls inside panel2 using this event

All the details to do this can be found at:
http://www.codeproject.com/KB/user-controls/Page_UserControl.aspx
Look under the Event Driven Communication section

BTW this is a great page and will show you several ways to do what you are trying to do. But looking at your code you are already using events so this seems the logical progression. Reading the whole page will make it easier to understand.

Alternatively, if your DealerSearchControl  is always used like this (and won't be used in a significantly different way elsewhere) you could encapsulate all this functionality into the DealerSearchControl , rather than having to make the control raise its own events to be handled by the host page.
