[Solved] Detail Table is empty during client side databinding

[Satyaprakash J]

Hi,
  I am using a RadGrid with a MasterTable and 2 Detail Tables. I am binding the detail table client side using the following javascript code.

function HierarchyExpanding(sender, args) {

    detailTableView = sender.get_detailTables()[2];
    WebService.GetDetails(updateDetailTable);



}

function updateDetailTable(result) {
    alert("Updating");
    alert(result.length);
    alert(result[0].DealId);  // result is a C# List<CustomClass>

    detailTableView.set_dataSource(result);
    detailTableView.dataBind();


}

But the detail table comes blank. Please let me know if I am missing something.

Thanks

Hi Satyaprakash,

Hierarchical grid structure with client binding is not a supported scenario. The furthest you can get in this direction is demonstrated in the following blog post:

I hope this helps.

Hi,
    I checked the link http://blogs.telerik.com/vladimirenchev/posts/08-09-09/how_to_telerik_radgrid_master_detail_client-side_data-binding_using_linq_to_sql_and_webservice.aspx . The code mentioned in the link uses a NestedViewTemplate within the MasterTableView whereas I am using DetailTable. Does this mean that ClientSide Databinding works for NestedViewTemplate and not for DetailTable.

Also I checked the link http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/hierarchyloadmodeclient/defaultcs.aspx. Could you please let me know why it works in this case.

Thanks

Hello Satyaprakash,

You are correct that client-side binding does not work with detail tables - this is not a supported scenario. You can work, to some extent, around the issue in the way shown in the blog post using nested view templates.

As for the example, you have mentioned - please, note that it features a hierarchical grid bound on the server. In this case client-side hierarchy loading refers to a different feature of the gird, namely, the capability to expand/collapse the items in the browser, which is achieved by setting the HierarchyLoadMode="Client" property of the corresponding table view and is much faster. More information you can find at the following help topic: http://www.telerik.com/help/aspnet-ajax/grdhierarchyloadmodes.html
