PageMethod bound Grid with FilterTemplates

[Nick]

I have a grid that is using declarative client side binding to a aspx pagemethod to get data which works fine.

<telerik:RadGrid ID="rgDiscoveries"
                 runat="server"
                 AllowFilteringByColumn="True"
                 AllowSorting="true"
                 AllowPaging="True"
                 GridLines="None"
                 AutoGenerateColumns="true" Culture="en-GB">
  <ClientSettings>
    <DataBinding Location="Default.aspx" SelectMethod="GetDataAndCount" />
  </ClientSettings>
...

I have added a FilterTemplate to one column which has a ComboBox in which pulls a listing from a second page method.

<telerik:GridBoundColumn DataField="ScriptName"
                         HeaderText="Script Name"
                         UniqueName="scriptName"
                         DataType="System.String">
  <FilterTemplate>
    <telerik:RadComboBox ID="filterScriptName"
                         runat="server"
                         EmptyMessage="Select a script"
                         EnableLoadOnDemand="true"
                         ShowMoreResultsBox="true"
                         EnableVirtualScrolling="true"
                         OnClientSelectedIndexChanged="filterScriptName_SelectedIndexChanged">
      <WebServiceSettings method="GetScriptNames" Path="Default.aspx" />
    </telerik:RadComboBox>
  </FilterTemplate>
</telerik:GridBoundColumn>

The combobox is populated but I don't know how to trigger the grid to repopulate when the combobox SelectedIndexChanged event fires.

function filterScriptName_SelectedIndexChanged(sender,args) {
  tableView.filter("ScriptName", args.get_item().get_value(), "EqualTo");
  // What goes here??
}

Is there an example of this somewhere please?

Cheers,
Nick

Hi Nick,

Could you pelase try calling the dataBind() client method for the grid and see if it helps?

Hi Iana,

I'm afraid I got impatient and opened a support ticket (367214)

If you have any ideas on that they would be most gratefully received.

Cheers,
Nick

Ok, turns out that the reason this didn't work is that the parameters passed into the filter function are case-sensitive  :(

tableView.filter("ScriptName", args.get_item().get_value(), "EqualTo");

needs to be

tableView.filter("scriptName", args.get_item().get_value(), "EqualTo");

I hate case sensitive languages....

Nick,

Programming language case-sensitivity has nothing to do with RadGrid's column names keeping a case-sensitive naming convention. This is by design and we cannot change it as it may lead to breaking changes in other customers' applications who prefer having case-sensitive column names and have incorporated some application logic based on that.
