[Solved] Expand All / Collapse All using Server-On-Demand

[Mark]

Hi

Is there a way to expand all the detail tables for a hierarchal grid that uses a server-on-demand approach?

If a grid uses "Client" I can get this working nicely, but I'm not sure how to approach this with server-on-demand.


Kind regards

Hi mark,

Try setting the HierarchyDefaultExpanded property to true in the aspx as shown below.

ASPX:

  <MasterTableView  HierarchyLoadMode="ServerOnDemand"  HierarchyDefaultExpanded="true"   DataSourceID="SqlDataSource1">

Thanks

Sorry Shinu, I should have been more specific.

I have an external button that needs to expand all / collapse all the grid.

Using Javascript, is there a way to 'click' each hierarchy so that it does a load-on-demand?

Also how would the reverse of this be true when collapsing all hierarchies.



Kind regards

Hi,

Try the following code snippet.

ASPX:

  <asp:Button ID="Button1" runat="server" Text="Expand/Collapse" OnClick="Button1_Click" />

CS:

  protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.Items)
        {
            item.Expanded = !item.Expanded;

        }
    }

Thanks
Princy.
