Bind data to grid according to selected row in other grid

[Covertix]

I have 2 grids:

The first one displays tasks and the other one displays tasks settings.

I want to bind data to the second grid based on the selected task id (selected row of the first grid).

Is there any way to implement this functionality?

I tried:

<telerik:RadGrid ID="rgTasks" runat="server" OnNeedDataSource="rgTasks_NeedDataSource" Skin="Gray" AutoGenerateColumns="false" OnSelectedIndexChanged="rgTasks_SelectedIndexChanged">

    protected void rgTasks_SelectedIndexChanged(object sender, EventArgs e)
    {
        String ID = rgTasks.SelectedValue.ToString();
        rgTaskData.DataSource = GetData(ID);
        rgTaskData.DataBind();
    }


But rgTaskData remains empty

Hi Tzach,

Please note that using DataBind() to bind the grid is not recommended. Performing complex grid operations such as Inserting, Deleting, Updating, Hierarchy relations, Grouping, Exporting, Paging, Sorting, Filtering, etc. require accommodating appropriate database operations.  Therefore, we suggest you to avoid Simple Databinding and strongly recommend the use of more advanced databinding methods, which automatically handle the aforementioned functions:
Declarative DataSource
Advanced Data Binding

As for your main requirement, I suppose you are looking for something similar to this:

Or this:

I'm also sending a sample RadGrid web site to demonstrate a basic implementation. Please run the attached application and let me know if it helps you.
