I have a read only grid control on the web. When you click on a row i want to be able to display whole bunch of information on the right side of the grid. For example lets say you have a first name and last name showing on the grid. Upon clicking on the grid row user can see further information such as address, email, etc on that user on the right side of the grid.
My questions are
#1 the SelectedIndexChanged doesn't fire why? am i doing something wrong?
#2 I see the manual say use a checkbox. It doesn't really work for me but I figured i place a checkbox on the grid( i don't see an option for autopostback on the checkbox column). Anyways, I run the app and the checkbox is disabled ( i can't click on it).
Can someone help me here?
Thanks

Rebind ComboBox with multiple checked check boxes

Hi

I'm using a RadComboBox with check boxes and server side when the user saves the form I insert using the following:

var sb = new StringBuilder();

var collection = ddlAdditionalStaff.CheckedItems;

foreach (var item in collection)

sb.Append(item.Value + "|");

Which leaves me with a field in my database table eg. Fred|Mark|Gary|

My question is how can I rebind this field to the RadComboBox with Checkboxes when the user edits the form. I have tried the text, selected value and checkeditems without luck. I have seen in the documentation the DataCheckedField can be used, but I do not understand it's use so could do with some clarification.

Any help would be greatly appreciated.

Dynmically Created RadGrids, Exporting to Excel

This is what I'm trying to achieve:

I have some data that I want to export using a click of a button. When the user clicks the export button, I'm creating mutliple RadGrids dynamically, adding them to the form, and triggering the ExportToExcel() method.

This is part of the code:

For Each Vendor_ID As Integer In hashDataByVendor.Keys

Dim tempRadGrid As New Telerik.Web.UI.RadGrid

Dim dtVendor_ID As System.Data.DataTable = hashDataByVendor(Vendor_ID)

tempRadGrid.DataSource = dtVendor_ID

Dim vendor As New Vendor(Vendor_ID)

tempRadGrid.ID = String.Format("{0}-{1}", vendor.Vendor_Name, Date.Now.ToString("MMddyyyy_HHmmssfff"))

tempRadGrid.MasterTableView.Caption = String.Format("{0} ETA List for {1}", vendor.Vendor_Name, Date.Today.ToString("MM/dd/yyyy"))

Dim tempColumnGrid As New Telerik.Web.UI.GridBoundColumn

tempRadGrid.MasterTableView.Columns.Add(tempColumnGrid)

tempColumnGrid.DataField = "Task_ID"

tempColumnGrid.HeaderText = "Task ID"

tempColumnGrid.ItemStyle.HorizontalAlign = HorizontalAlign.Left

tempRadGrid.MasterTableView.ShowHeader = True

tempRadGrid.AutoGenerateColumns = False

tempRadGrid.ExportSettings.HideStructureColumns = False

tempRadGrid.ExportSettings.ExportOnlyData = True

tempRadGrid.ExportSettings.FileName = String.Format("{0} - {1}", vendor.Vendor_Name, Date.Now)

tempRadGrid.ExportSettings.OpenInNewWindow = True

Page.Controls.Add(tempRadGrid)

tempRadGrid.DataBind()

intTempVendor_ID = vendor.Vendor_ID ' Store the current vendor_id so we can use it in the GridExporting Sub.

tempRadGrid.MasterTableView.ExportToExcel()

AddHandler tempRadGrid.GridExporting, AddressOf tempRadGrid_GridExporting

intVendorsCounter += 1

Next

When there is only ONE Grid created through this loop - everything works fine.

When there is more then one Grid created I'm getting an error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Source Error:

Line 355: tempRadGrid.ExportSettings.FileName = String.Format("{0} - {1}", vendor.Vendor_Name, Date.Now) Line 356: tempRadGrid.ExportSettings.OpenInNewWindow = True Line 357: Page.Controls.Add(tempRadGrid) Line 358: tempRadGrid.DataBind() Line 359: intTempVendor_ID = vendor.Vendor_ID ' Store the current vendor_id so we can use it in the GridExporting Sub.

Any clue on how to solve this matter?

Center dropdown

Is there a simple way to have the dropdown (the "child menu") centered instead of aligned left or right? I guess you could write a function to calculate it and then use OffsetX property, but that seems very complicated. This should be a standard option I believe in the designer.
