[Solved] What event fires when you expand a row?

[Forest]

I have a grid - basic hierachy. 

Why I expand a column to open up the details table, what event fires?

I'd like to change some of the detailstable column upon expanding.

Thanks,

Forest

Hello Forest,

Here is an example:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.ExpandCollapseCommandName)
    {
        //your code
    }
}

Thanks.

When the event fires, is the detailstable already databound or not yet?

What I'm trying to do is - after expanding the row - iterate through the rows of the details table (the second level fo the heirarchy) and put them in edit mode so the user can start editing right away instead of pressing an edit button.

Any suggestions ?

Hello Forest,

You can try out the following code to achieve the required scenario:
c#:

 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
        {
            if (dataItem.Expanded)
            {
                    GridTableView nestedView = (GridTableView)dataItem.ChildItem.NestedTableViews[0];

                    foreach (GridDataItem item in nestedView.Items)
                    {
                        item.Edit = true;

                    }
                    nestedView.Rebind();

            }
        }

Thanks
Princy.

I had to combine both of your solutions to get everything in edit mode.  It works, but with one problem.

The child grids do not retain their values after I change them - if I collapse a panel, it rebinds back to the original data from the db.  Anyway I can stop this and have the grid update the values for each cell.  I don't see an UpdateCell method.

Thanks,
