Ajaxified RadGrid SortExpression Out of Range on Repeated Sorts

I'm using an ajaxified RadGrid to display a long List<T> in a multi-tier environment. I've implemented a custom paging solution and I'm passing the SortExpressions[0] information to my next tier. This works fine for the first few sorts then I start to get an argument out range expression.

Columns Collection - names

This may be a dumb question but when I go into the columns collection editor and set some columns up I do not see the names of the columns or anything useful in the column list on the left of the dialog I just see stuff like:

0 GridBoundColumn
1 GridBoundColumn
2 GridBoundColumn

Am I missing something? I had hoped I would see something more like:

0 CustomerID
1 CustomerName
2 ZIP

etc

I am setting the bindings manually rather than having them generated.

[Solved] How to get rid of update panel / triggers in "My Portal"

From the Telerik Ajax documentation:

"There are some known issues when using both the manager and the panel in some complex applications - MasterPage or WebUserControls. However, note that a single RadAjaxManager (and no panels) in the master/main page could handle all the scenarios."

In the "My Portal" example there is a standard asp update panel being used (with triggers).

In aspx:
 <asp:UpdatePanel runat="server" ID="UpdatePanel1">
 </asp:UpdatePanel>

In code-behind:

 private void CreateSaveStateTrigger(RadDock dock)
 {
 //Ensure that the RadDock control will initiate postback
 // when its position changes on the client or any of the commands is clicked.
 //Using the trigger we will "ajaxify" that postback.
 dock.AutoPostBack = true;
 dock.CommandsAutoPostBack = true;

 AsyncPostBackTrigger saveStateTrigger = new AsyncPostBackTrigger();
 saveStateTrigger.ControlID = dock.ID;
 saveStateTrigger.EventName = "DockPositionChanged";
 UpdatePanel1.Triggers.Add(saveStateTrigger);

 saveStateTrigger = new AsyncPostBackTrigger();
 saveStateTrigger.ControlID = dock.ID;
 saveStateTrigger.EventName = "Command";
 UpdatePanel1.Triggers.Add(saveStateTrigger);
 }

We are using a similar approach to this example in our code and I'm trying to switch to just using a Telerik Ajax Manager on master page and proxies as needed on regular pages/controls.

What would the changes to the above example be to get rid of the update panels / triggers?

Thanks.

RadAjaxManager including RadComboBox - performance problem

Hello,

We have a page with RadAjaxManager and RadComboBox on it.
When we fill the RadComboBox with normal amount of items (up to 300 items), the performance is good.
We need to fill the RadComboBox with more then 3000 items and then the performance is very slow.
When we remove the RadAjaxManager from the page, and the page works with regular postbacks, the page loading is quick even that 3000 items are filled into the RadCombobox.

Is there a known bug of RadAjaxManager when working with RadComboBox that filled with large amount of data?

Thanks,

Inbal

RadMenu Template with Databinding

hi
I am trying to create a RadMenu that looks like this demo:

(http://www.telerik.com/DEMOS/ASPNET/Prometheus/Menu/Examples/Functionality/Templates/DefaultCS.aspx).

This demo creates the items declaratively. I need for them to come from the database.

Just like in the demo link above, I want the top level parent to be a simply menu item, but I want the child menu items to all use a template like in the demo but also populated from database .
the same message Posted on Jul 16, 2008 by Michael , but there's no answer, I hope to know if there's

thanks

[Solved] Sum column of filtered grid rows only

How do I sum only the columns that are in the grid after it has been filtered? I can only seem to get the sum of all of the values for the column before it was filtered.

After the filter has been performed and the datasource set and the grid rebound, I have the followjng code which loops through the grid and sums the column. But it always shows the sum of all rows from the original datasource and not the filtered rows:

For Each item As GridDataItem In rgT.MasterTableView.Items

lblAmt =

CType(item.FindControl("lblTransAmount"), Label)

Try

transTotal += System.Convert.ToDouble(Replace(lblAmt.Text,

"$", ""))

Catch ex As Exception

lblUpdMsg.Text =

"There was an error summing the transactions. " & ex.Message

Exit For

End Try
