HeirArchy Grid Edit in DetailTable

[Mike]

I have an edit Icon on the far right column of the grid and when a users clicks on it how can I get the grid to expand all of it's children just like the arrow does on the left hand side?

Hello Mike,

I suppose you mean the ExpandAll functionality demonstrated in the following sample:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/declarative-relations/defaultcs.aspx

You can achieve this on an external button click using this approach:

<script type="text/javascript">
    //Put your JavaScript code here.
    function expandAllGridItems() {
        var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
        var expandAllButton = $telerik.findElement(masterTable.HeaderRow, "AllBtnExpandColumn");
        expandAllButton.click();
    }
</script>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="expandAllGridItems(); return false;" />

Hope this helps. Please give it a try and let me know if it works for you.

Regards,
