If I put the following in the ASPX: <MasterTableView FilterExpression="([Active] = True)"> and put the CurrentFilterFunction="EqualTo" and CurrentFilterValue="True" on the GridBoundColumn Named Active The filter is set but does not filter the records.

If I put this in the codebehind on the NeedDataSource Method:

protected void rgManage_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

rgManage.DataSource = GetDataSet();

if (!Page.IsPostBack)

{

rgManage.MasterTableView.FilterExpression = "([Active] = True)";

GridColumn column = rgManage.MasterTableView.GetColumnSafe("Active");

column.CurrentFilterFunction = GridKnownFunction.EqualTo;

column.CurrentFilterValue = "True";

}

I get the following error on page load:

Expression expected

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Telerik.Web.UI.ParseException: Expression expected

What am I missing here? Active is a boolean datatype.

VS2010 & Telerik.Web.UI_2010_2_713_Dev.msi

Hello, guys.
I've downloaded Telerik.Web.UI_2010_2_713_Dev.msi installation package and thought that now life will get much better.
Not a bit!
I uninstalled previos version of telerik ajax controls.
After installation I noticed the welcome message (something like "You hav just installed telerik...'). Toolbox looks ok.
But under Telerik menu I only can see "About" item and nothing more.
Any Telerik application templates have also disappeared.
Has anyone faced this?

With respect, Valery.

[Solved] Binding Hierarchial Grid based on Expand button clicks

Hi,
I am using RadGrid,which is having the feature of Hierarchial grid. I used to bind the Hierarchial table under DetailTableDataBind event of parent grid.
Everything is working fine, but i would like to bind the child or hierarchial grid only at the time the Expand button clicks, so that i can improve the speed and enable the grid to bind only at the time of expanding.

So please let me know the possibilities to achieve the scenario

-Thanks

RadAjaxPanel _doPostBack (HOW?)

I'm currently converting a working appplication and integrating Telerik into it for a school capstone project.

What I need to know is how do we perform a postBack call on the RadAjaxPanel?

For instance, with MS AJAX I can enter the following Javascript into the head of my page:

<script language="javascript" type="text/javascript">

function connectLogin() {

var prm = Sys.WebForms.PageRequestManager.getInstance();

prm._doPostBack('UpdatePanel1', '');

}

setTimeout("connectLogin()", 10000);

</script>

that code will cause my UpdatePanel to basically refresh!

<div>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<ContentTemplate>

...

</ContentTemplate>

</asp:UpdatePanel>

</div>

Any help with this would be great, I've looked over numerous pieces of code on the site here, tried several things and I'm not getting anywhere!

Thanks!
