[Solved] Problems with detail table collapse and edit mode

[Stefan]

Hi,

we've a grid with 3 levels. The second and third levels are set to edit mode in the prerender event of the grid.
The problem is, that it is possible to expand these levels. but collapsing doesn't work anymore?!

Here is the sample code:

protected void RadGridContractProducts_PreRender(object sender, EventArgs e)
{
        for (int i = RadGridContractProducts.MasterTableView.GetItems(GridItemType.NestedView).Length - 1; i >= 0; i--)
            {
                for (int j = ((GridNestedViewItem)RadGridContractProducts.MasterTableView.GetItems(GridItemType.NestedView)[i]).NestedTableViews.Length - 1; j >= 0; j--)
                {

                    SetItemsMode(((GridNestedViewItem)RadGridContractProducts.MasterTableView.GetItems(GridItemType.NestedView)[i]).NestedTableViews[j]);
                }
            }


            RadGridContractProducts.Rebind();
        }

private void SetItemsMode(GridTableView oGridTableView)
        {
            for (int i = oGridTableView.Items.Count-1; i >= 0; i--)
            {

                oGridTableView.Items[i].Edit = true;

            }


            for ( int i = oGridTableView.GetItems(GridItemType.NestedView).Length -1; i >=0 ; i-- )
            {
                for ( int j = ( ( GridNestedViewItem )oGridTableView.GetItems(GridItemType.NestedView)[i]).NestedTableViews.Length -1 ; j >=0; j--)
                {
                    SetItemsMode(((GridNestedViewItem)oGridTableView.GetItems(GridItemType.NestedView)[i]).NestedTableViews[j]);
                }

            }
        }

Could someone explain how to get this problem solved?

Thanks in advance

Hello Stefan,

This approach and functionality should not break the expansion functionality of the nodes. Based on this information and code snippet, however, it is hard to determine what is the cause of the problem. If the issue persists, you can open a formal support ticket, and send us the problematic implementation for additional testing and research.

All the best,

Stefan,

I was able to get the expand/collapse to work with by adding the following code to the ItemCommand event handler:

        void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
        {
            var commandName = e.CommandName;

            if (commandName == "ExpandCollapse")
            {
                if (e.Item.Expanded == true)
                {
                    e.Item.Expanded = false;
                    e.Item.OwnerTableView.Rebind();
                    e.Canceled = true;
                }
            }        
        }

I have a grid with 3 levels also.  My problem now is how to put the MasterTableView in edit mode, level 2 in normal mode, and level 3 in edit mode and have the expand/collapse work accordingly.  Currently, any views not in edit mode does not expand.

Thanks in advance.
