Change header text property into hierarchical datagrid

Hello,

I've try to change the HeaderText property into hierarchical datagrid (DetailTable) but I can't change it.

This is my code:

   protected void RG1_DetailTableDataBind(object source, GridDetailTableDataBindEventArgs e)
   {
   switch (e.DetailTableView.Name)
   {
   case "DeviceID":

   break;

   default:
   break;
   }
   }

Do you have others solutions?

Information about error message received when trying to edit records in pop up edit forms

A property named 'TextBox2' was not found on the entity during an insert, update, or delete operation. Check to ensure that properties specified as binding expressions are available to the data source.

I have a pop-up edit form that I use to edit data. I am able to pull up the form and after I make changes to a text box item in the form, this is message I receive when I click the forms update button.

It seems that I must expose these textboxes to the Data Source that I created, but I am not sure how to do it, or even if this is the action that the data sources is asking me to do.

Any ideas, or information would be very helpful. Been reading the forums and viewing demos, but did not find a post or demo that explained how to do this.

Thanks!

RadGrid Edit Form Not Closing

I am trying to close the edit form of this RadGrid:

<telerik:RadGrid ID="rgAccountRangeSet" runat="server"

AutoGenerateColumns="False" GridLines="None" AllowAutomaticDeletes="True"

AllowAutomaticInserts="True" AllowAutomaticUpdates="True"

PageSize="25" AllowPaging="True" AllowSorting="True" >

<PagerStyle Mode="NumericPages" />

<MasterTableView AutoGenerateColumns="False" CommandItemDisplay="Top" CommandItemSettings-ShowRefreshButton="False"

HorizontalAlign="NotSet" DataKeyNames="Id">

<CommandItemSettings AddNewRecordText="Add New Account Range" AddNewRecordImageUrl="~/images/Keymaster/add.gif"/>

<NoRecordsTemplate>

<center>No records available</center>

</NoRecordsTemplate>

<Columns>

</Columns>

<EditFormSettings>

<EditColumn ButtonType="PushButton" />

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

With the following code:

Private Sub rgAccountRangeSet_InsertCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgAccountRangeSet.InsertCommand

'code to handle insert items has been removed

rgAccountRangeSet.Rebind()

rgAccountRangeSet.MasterTableView.IsItemInserted = False

End Sub

However, I am getting an exception. When I remove "IsItemInserted = False" assignment, the exception goes away. I also want to mention that I am opening the page in certain scenarios with "IsItemInserted = True" with no problem. The grid opens fine and displays the edit form. Any ideas?

Thanks in advance!!

Add new record doesn't save

I've got an ASP.NET Master/Content page combination with a grid pointing to an EntityDataSource. (I'm using my simplest Entity, which just has a RoleId (PK) and Name.) The Entity set is currently empty, and when I use the "Add new record" button to add a record, I get the form showing up correctly. When I click "Insert" after assigning the RoleId and Name, the dialog goes away, but the item isn't added to my collection.

I've got all the "automatic" flags set for editing, inserting, and deleting in both the EntityDataSource and the Grid. What else do I need to set up to have the values saved to the entity collection?

How to select a row via server code?

I have a combo-box which provides a list of objects. When the user selects the item in the combo-box, it is bound to an ObjectDataSource. That ObjectDataSource is bound to a RadGrid which auto-populates the grid. This works great.

In this scenario, how do we get the first row of that grid to be selected whenever the user picks a new value in the combo-box? We have tried the grid's pre-render event and the ObjectDataSource's selected event. None of these work as the data has not yet been populated into the grid.

We also tried the grid's ItemBound event; however, it fires with every event on the grid it seems. We only need it to set the first row when new data has been bound.

Any suggestions on which event to use?

RadGrid not displaying data available in NeedDataSource event

All,

I am having an issue displaying data in my grid using Telerik AJAX controls v. 2010.3.1317.35. I have no idea why, as numerous other grids in other user controls on the same page are displaying fine. I can see in my NeedDataSource event that the oARAC collection object has data, and that the column name in the query is correct in the grid column. I can also see the grid shows 2 empty rows, so for some reason the grid is interpreting the data "4999220" as  

I have confirmed that the NeedDataSource event is not firing twice when loaded, and I am not getting any exceptions.

Below is the code, and attached are the images of what is going on as I debug.

Any and all help is greatly appreciated!

Thanks,
Bruce
