Accessing RadGrid entity datasource's field values in code behind

This seems like it should be a straight forward thing to do, but it's eluding me, and I've searched for an answer. Hopefully I'm overlooking something simple.

I'm binding my RadGrid to an entity data source. I'm using GridTemplateColumn columns for many of the columns, as I combine several of the data fields into one column. How do I access the RadGrid datasource's field values (in the code-behind)? This is in non-edit, regular view of the grid.

For example, I'd like to do something like this:

protected void ContactsGrid_ItemDataBound(object sender, GridItemEventArgs e)

{

if ((!e.Item.IsInEditMode) && (e.Item is GridDataItem))

{

GridDataItem dataItem = (GridDataItem)e.Item;

// Assuming my entity data source has a field named "dataFieldName", would be nice to access:

string dataFieldValue = (string)dataItem("dataFieldName"

).Value; 


        // Would then find the GridTemplateColumn in order to fill in the ItemTemplate, 

        // which already know how to do...

}

Thanks,
Steve

Radeditor edit the text after click twice

Hi,

I am using rad editor to edit some text. I have a edit button to edit text on radeditor
On the edit button click I am setting some property of radeditor.

<telerik:RadEditor ID="radEditor" runat="server" Enabled="false" Skin="Office2007" TextMode="MultiLine" Width="625px"></telerik:RadEditor>

radEditor.Enabled =

true;
radEditor.Width = 625;

radEditor.ToolsFile =

"RadEditorBasicToolSet.xml";

After I click on edit button, I have to click twice on text in the radeditor to edit. I don't want to click twice to edit the text. How can I fix that double click issue.

Thanks

Access PageSize for Radpager in Layout

I am using a RadListView per the sample at http://www.telerik.com/help/aspnet-ajax/listview-datapager-for-paging.html
The Datapager is in the layout template. I want to access the PageSize of the Radpager in the code behind but I can not find it to set. Since it is in the Layout template it is not visible in the VS dropdown. I tried to simply place a value in the PageSize using <% =value%> and I get an error saying that the string value cannot be translated to Int32. I verified that the value is in fact a number. I tried to do a RadListView1.LayoutTemplate.FindControl but this not supported. Please help, my client really wants to be able to set this page size dynamically and I can find no way to get to this.

Thanks in advance for your help.

ConfirmDialogHeight="130px">

<ItemStyle Width="20px" HorizontalAlign="Center" VerticalAlign="Middle" />

</telerik:GridButtonColumn>

</Columns>

</telerik:GridTableView>

The error is:

Microsoft JScript runtime error:
Sys.WebForms.PageRequestManagerServerErrorException: Exception has been thrown by the target of an invocation.

If I write the same code in a bind column all works fine.

Regards
Jose

Update specific field of all selected rows

I have a radgrid on my page and I have it set up so that I allow multiple selections via a checkbox.

I want to be able to get the selected rows checked and update their field(status) to a certain value.

I want to use a command button for this. the user will select the records and click the button which will update "status" to "confirmed".

Is this possible to be done through a stored procedure? If not, just through vb.net

Thanks
