Issue with FIlterExpression of RadGrid using toggle button in FIlter template

[Ruchi]

Hello Team,

I am working on Web Application. used FIlterTemplate in GridBoundColumn of RadGrid.

Placed RadButton in Filter template with Toggle type : "CustomToggle" and ButtonType : "ToggleButton".

In preRender Event of Radgrid, I found grid.mastertableview.FIlterExpression is Empty.

Please find below Script used OnClientToggleStateChanged :

<telerik:RadScriptBlock ID="RadScriptBlock2" runat="server">
<script type="text/javascript">
function ToggleStateChanged(sender, args) {
var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
if (args._currentToggleState._attributes.text == "All") {
  tableView.get_filterExpressions().clear();
}
else {
   tableView.filter("UserName", "<%= Context.User.Identity.GetUserName() %>", "EqualTo");                                                                                }
}
</script>
</telerik:RadScriptBlock>  

Can anyone help me out? stuck with a simple filter functionality.

Thanks and Regards,

Hi Ruchi,

To achieve this behavior, you can filter the column with empty value or NoFilter function as demonstrated in this live sample:

Hope this helps.

Hello Eyup,

Thank you for the reply.

I tried the same as well. but on code behind i didn't get the Filter expression.

as mentioned in example you send:
  protected void RadGrid1_PreRender(object sender, System.EventArgs e)       
{           
if (RadGrid1.MasterTableView.FilterExpression != string.Empty)           
{               
RefreshCombos();           
}       
}       
protected void RefreshCombos()      
 {           
SqlDataSource2.SelectCommand = SqlDataSource2.SelectCommand + " WHERE " + RadGrid1.MasterTableView.FilterExpression.ToString();           
}

getting "RadGrid1.MasterTableView.FilterExpression" as Empty.

Thanks and Regards,
