or
any alternative solution for the above requirement
or
Find the controls inside the Form Template in the page load event

I have checked this link.
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/templateformupdate/defaultcs.aspx

Grid with DomainDataSource

Hello,

I'm trying use domain data source with RadGrid in ASP.NET 4.0 project (by this demo http://demos.telerik.com/aspnet-ajax/grid/examples/programming/domaindatasource/defaultcs.aspx). I'm using LinqToEntitiesDomainService (EntityFramework).

<telerik:RadGrid ID="groups" runat="server" AllowPaging="true" DataSourceID="dsGroups">

<MasterTableView CommandItemDisplay="Top" AllowAutomaticInserts="true" AllowAutomaticDeletes="true"

AllowAutomaticUpdates="true" AutoGenerateColumns="false" DataKeyNames="GroupId">

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton" />

<telerik:GridBoundColumn DataField="Name" HeaderText="Name" />

<telerik:GridBoundColumn DataField="Description" HeaderText="Description" />

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Delete" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

<asp:DomainDataSource ID="dsGroups" runat="server" DomainServiceTypeName="DataSources.GroupsDomainService"

EnableDelete="True" EnableInsert="True" EnableUpdate="True" QueryName="GetGroups">

</asp:DomainDataSource>

I'm getting following error:

format column from code behind

I have a radgrid which displays data that is entered from rad editor. The problem is that the grid shows several char values instead of the way it was entered.

The grid is bound from code being and I dont have an option to set the format of the column to HTMLEditorColumn in desing view. I was thinking to do this in code behind but did not know how to do that.

can you please provide some light on the same

general structure of the code is

RadGrid1.DataSource = DataTable
RadGrid1.DataBind()

For z = 0 To RadGrid1.MasterTableView.RenderColumns.Count - 1

If <some condition to identify column> then
RadGrid1.MasterTableView.RenderColumns(z). -- what should the code be here to set the correct format of the column
End if

Next

Also, can this be done in the pre-render event or does this need to be done somewhere else. Any help provided will be much appreciated.

Get all buttons client-side

Hi,

I need to get buttons by their attributes (these attributes are set server-side). These buttons need to be activated, all other buttons must be deactivated. With activated I mean "visible", not "enabled".

How I can I get a collection of all buttons attached to the RibbonBar and how can I get their attributes?

Thanks!

Using advanced edit templates

I am using a RadScheduler, and have some issues. I cant seem to get rid of the edit templates. What i have done is, in the OnClientAppointmentDoubleClick event, i do some custom Javascript code. I want only this code to run, and dont want to see any edit templates etc from the telerik control. But when i run this, the template for editing is displayed when i double click an appointment. How can I avoid this? I have set AllowEdit="False", but that does not seem to help. And i cannot catch the AppointmentEditingEvent from this post:http://www.telerik.com/community/forums/silverlight/scheduler/how-to-disable-some-features-of-radscheduler.aspx
for 2 reasons:
1. I still want the user to be able to expand an item by clicking and dragging.
2. There IS NO SUCH EVENT on the Scheduler control.

How can I disable the edit template showing up when double clicking an appointment?

What I actually want to do is:
- User double clicks an appointment
- Hide scheduler
- Show a hidden panel
- Put ID, subject, start and end of the clicked appointment into textboxes inside the new panel

And I would like this panel to be TOTALLY INDEPENDANT of the Scheduler. Possible?
