I'm trying to figure out how to remove rows from the child template of a on-demand loaded child. I can do this no problem with a standard command button on the Master template, but the child doesn't want to make the row go away.... 
private void uiProductsGrid_CommandCellClick(object sender, EventArgs e)
        {
            GridCommandCellElement button = (GridCommandCellElement) sender;
 
            if (button.RowInfo.HierarchyLevel == 1)
           {
               DataRowView drv = (DataRowView)button.RowInfo.DataBoundItem;
               Guid id = (Guid)drv["Id"];
 
               Selection.DeleteSelection(id);
               button.MasterTemplate.Rows.Remove(button.RowInfo);
               return;
           }
            if (button.RowInfo.HierarchyLevel ==2)
           {
               Guid id = Guid.Parse(button.RowInfo.Cells["Id"].Value.ToString());
               Product.DeleteProduct(id);
                // What do I put here to remove this row from the grid???
               return;
           }
           
        }

Hi Pawz,

You can use the same approach that you are using for the rows at the first level. You can use the following code snippet as a sample:

private void uiProductsGrid_CommandCellClick(object sender, EventArgs e)
{
    GridCommandCellElement button = (GridCommandCellElement)sender;
    GridViewRowInfo row = button.RowInfo;
 
    if (row.HierarchyLevel == 1)
    {
        DataRowView drv = (DataRowView)row.DataBoundItem;
        Guid id = (Guid)drv["Id"];
        Selection.DeleteSelection(id);
    }
    else if (button.RowInfo.HierarchyLevel == 2)
    {
        Guid id = Guid.Parse(row.Cells["Id"].Value.ToString());
        Product.DeleteProduct(id);
        // What do I put here to remove this row from the grid???
    }
 
    row.Delete();
}

I hope this helps.

Kind regards,
