[Solved] Hide rows in a 1 level hierarchy Grid

[Nuno]

 

Hi all,

I've a RadGrid with one detailTable level.

My goal is to when editing one row in the detailTable, the other rows (not selected) should disappear,
 as well as the only visible row in the Main Grid should be the parent row (wich is actually expanded)

I tryed the code below but it's not working.

            foreach (GridDataItem dataItem in RadGrid1.Items)
            {
                if (RadGrid1.EditItems.Count > 0)
                {
                    if (!dataItem.Expanded)
                    {
                        dataItem.Visible = false;
                    }
                    else
                    {
                        foreach (GridDataItem item in RadGrid1.MasterTableView.Items[0].ChildItem.NestedTableViews[0].Items)
                        {
                            if (item != RadGrid1.EditItems[0])
                            {
                                item.Visible = false;
                            }
                        }
                    }
                }
            }

Any help is very appreciated.

Hi Nuno,

Try the following code snippet and see whether it helps.

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    if (RadGrid1.EditItems.Count > 0)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            if (item != RadGrid1.EditItems[0])
            {
                item.Visible = false;
            }
            foreach (GridDataItem itemDetail in item.ChildItem.NestedTableViews[0].Items)
            {
                if (!itemDetail.IsInEditMode)
                {
                    itemDetail.Visible = false;
                    itemDetail.Display = false;
                }
            }
        }
    }
}

Hi Shinu,

Your code is almost perfect. What happens is that all rows in the Detail Grid are not visible, and I need the selected row (for edition) to be the only visible row in the Detail Grid.

Let me know what you think.

Thank you.
