GridTemplateColumn runtime + freezing columns not working + Please reply ASAP

Hi,

I am binding a radgrid runtime using GridTemplateColumns. In my grid the first 3 columns should be freezed, and from other columns, some contains just lables, and some with radnumerictexboxes.
I've created columns using GridTemplateColumn successfully, but confused with assigning data to the grid. I need to give each lable and numerictextbox a different id, so that i can get the data from it to save in database.
So that is my first question..
1) How can I bind data with different IDs to each control in grid.
2) How can I freeze columns? If i bind grid using SqlDataSource, freezing works perfect, but when it bind it using GridTemplateColumns and all, freezing does not work.

Here is a sample code, please correct me where I am wrong:

<rad:RadGrid ID="radTestInputs" Width="100px" EnableAJAX="True" AutoGenerateColumns="false"

EnableAJAXLoadingTemplate="True" GridLines="None" AllowSorting="True" AllowPaging="True"

runat="server" Skin="WinXP">

<ClientSettings AllowColumnsReorder="True" ReorderColumnsOnClient="True">

<Resizing AllowColumnResize="True" EnableRealTimeResize="True" ResizeGridOnColumnResize="True" />

<Scrolling AllowScroll="True" UseStaticHeaders="True" FrozenColumnsCount="1" />

</ClientSettings>

<HeaderStyle Width="100px" />

</rad:RadGrid>

Partial Class DefaultVB

Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

BindGrid()

End If

End Sub

Public Sub BindGrid()

Dim templateColumnName As String = "Number"

Dim templateColumn As New GridTemplateColumn()

templateColumn.ItemTemplate = New MyTemplateCaption("Number")

templateColumn.HeaderText = templateColumnName

templateColumn.ItemStyle.Width = Unit.Pixel(80)

templateColumn.HeaderStyle.Width = Unit.Pixel(80)

templateColumn.DataField = "Number"

radTestInputs.MasterTableView.Columns.Add(templateColumn)

Dim templateColumnName1 As String = "Test"

Dim templateColumn1 As New GridTemplateColumn()

templateColumn1.ItemTemplate = New MyTemplateCaption("Test")

templateColumn1.HeaderText = templateColumnName1

templateColumn1.ItemStyle.Width = Unit.Pixel(80)

templateColumn1.HeaderStyle.Width = Unit.Pixel(80)

templateColumn1.DataField = "Test"

radTestInputs.MasterTableView.Columns.Add(templateColumn1)

Dim dt As DataTable = New DataTable()

dt.Columns.Add("Number")

dt.Columns.Add("Test")

Dim dr As DataRow = dt.NewRow()

dr(0) = "1"

dr(1) = "Test1"

dt.Rows.Add(dr)

Dim dr1 As DataRow = dt.NewRow()

dr1(0) = "2"

dr1(1) = "Test2"

dt.Rows.Add(dr1)

radTestInputs.DataSource = dt

radTestInputs.DataBind()

End Sub

End Class

Class MyTemplateCaption

Implements ITemplate

Protected lControl As LiteralControl

Private value As String, id As String

Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) _

Implements System.Web.UI.ITemplate.InstantiateIn

lControl = New LiteralControl()

lControl.ID = value 'How can I provide different id for each control here?

AddHandler lControl.DataBinding, AddressOf label1_DataBinding

container.Controls.Add(lControl)

End Sub

Public Sub New(ByVal cValue As String)

value = cValue

End Sub

Private Sub label1_DataBinding(ByVal sender As Object, ByVal e As EventArgs)

Dim target As LiteralControl = DirectCast(sender, LiteralControl)

Dim item As GridDataItem = DirectCast(target.BindingContainer, GridDataItem)

Dim row As DataRowView = DirectCast(item.DataItem, DataRowView)

If (target.ID.ToLower().Contains("number")) Then 'Not proper- here I Need to assign text according to the control's id

target.Text = row.Item(0).ToString()

Else

target.Text = row.Item(1).ToString()

End If

End Sub

End Class

I've to submit this by tomorrow, please reply whoever knows solution ASAP.
Thanks.

client event after reordering colum

I am using version Q1 2012 of the ASP.NET AJAX Controls.
I want to create a client-event where I register the column that has been moved and the position it has been dragged to.

I have created clientevents for OnColumnMovedToLeft and for OnColumnMovedToRight.

Within these events I can read

eventArgs.get_gridColumn()
This is not the column that has been dragged.
How do I get the correct dragged column with it's new position?

How to completely reset the AsyncUpload control

Hello

I would like to know how to reset the control completely.

My upload control is in a popup (a simple absolute div) and has its own "Close" button. When the popup is closed, I want the Telerik control to completely reset, whether or not it is currently uploading or what state it is ...

I have tried using:
- deleteFileInputAt(0);
- _uploading = 0; i'm pretty sure this is not the way to go...
- _cancelUpload: this crashes a lot ... (stackoverflows etc....)

I'm searching for a reliable method to re-initialize the control like when the page was loaded.

Thanks !
