Need To Always Show Insert Row With Detail/Child Grid

[Alex]

I have a grid with a single hierarchical child grid that the user may expand. I have the load mode set to "Client" and the edit mode set to "InPlace".

I want there to always be an insert row for the user to add new rows with if they wish. I have accomplished this with the master grid view (parent grid) with this function:

protected void radGrid1_PreRender(object sender, System.EventArgs e)
{
  if (!radGrid1.MasterTableView.IsItemInserted)
    radGrid1.MasterTableView.InsertItem();
}

 

This will cause there to always be an insert row.

However, with the child grid in client mode, there is no callback between expand and collapse for the child grids.

I've tried this with no success:

protected void radGrid1_PreRender(object sender, System.EventArgs e)
{
  if (!radGrid1.MasterTableView.IsItemInserted)
    radGrid1.MasterTableView.InsertItem();
  if (!rgPieces.MasterTableView.DetailTables[0].IsItemInserted)
    rgPieces.MasterTableView.DetailTables[0].InsertItem();
}

 

What am I supposed to do here?

[Alex]

Thats radGrid1 not rgPieces in the second example. I can't edit my post for some reason which is causing me a non-zero amount of frustration.

Any thoughts?

Hello Alex,

You can try to use the DetailTableDataBind event handler and set e.DetailTableView.IsItemInserted to True. Alternatively, you can traverse the inner tables manually and set the aforementioned property, but probably it would be too late in the page life cycle:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/how-to/hierarchy/hiding-the-expand-collapse-images-when-no-records

Here is an example:

protected void RadGrid1_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)
{
   ...

    e.DetailTableView.IsItemInserted = true;
}

I hope this will prove helpful.
