How to capture event in Child in Hierarchy grid

[Officialboss]

I have a 2-Level hierarchy grid binding with ObjectDataSource.

In the child grid I have a ASP Button in a template column.

How do I wire the button to that when it is clicked it does a partial postback to update or rebind the child grid or itself.

I have tried it like this but no luck.

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem dataItem = e.Item as GridDataItem;
        Button Button1 = (Button)(dataItem["TemplateColumn"]).FindControl("Button1");
        Button1.OnClientClick = String.Format(@"{0}.__doPostBack(""{1}"",""{2}"");return false;", RadAjaxManagerProxy1.ClientID, Button1.UniqueID, Button1.CommandArgument);

    }
}

Or using this:

GridTableView tableView = e.Item.OwnerTableView;
GridTableView detailView = tableView.Items[e.Item.ItemIndex].ChildItem.NestedTableViews[1];

Thanks

Hi Howard,

You can use the following code in order to check if the created item is of the MasterTableView or the detail table:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "DetailTableName")
    {
        //place your implementation here
    }
}

However, I suggest that you ajaxify the whole grid instead of adding ajaxsettings for each button in the detail table.

Find more about RadGrid hierarchy in the following articles:

Let us know if this helps.
