Combo Custom Attribute

Hi All

I am currently using the method below to poulate a combobox on the page load event:

Dim dataAdapter as new SetTableAdapter.someidentityTableAdapter

Dim adapterTable as DataTable

adapterTable = dataAdapter.getData()

Radcombo1.DataValueField = "Value1"

Radcombo1.DataTextField = "Value2"

Radcombo1.DataSource = adapterTable

Radcombo1.DataBind()

I would like to add a custom attribute to this combo box,
I am able to achive this in a load on demand senario but not the senario above!
Would someone be kind enough to point me in the right direction on how to achive this please?

Also when using custom attributes in this way is it still only possible to get the attributes value client side?

Many Thanks

Regards

Darren

Possible To Avoid Internal Caching (force async postback)?

I have a FileExplorer on a page with a very short logout period.

The problem is, when people are logged out, they are still able to click around the FileExplorers folders so long as they have visited the folders recently (the internal caching of the FileExplorer doesn't make another trip to the server).

Is it possible to have the FileExplorer not cache it's lists of flies, and ask the server when a folder is selected for the current list of files in that folder?

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?
