add new rows by default

[Avi Avni]

Hello

Is there option add new rows by default

 When the users get to the end of the row Like in SQL?

Best regards

Hello Ehud Pinchas,

The same insert functionality like in SQL in not supported by the GridView. You may achieve something close though by handling the RowEditEdit event of the GridView. 

private void clubsGrid_RowEditEnded(object sender, GridViewRowEditEndedEventArgs e)
       {
           RadGridView grid = sender as RadGridView;
           if (grid.SelectedItem == e.Row.Item && grid.Items.IndexOf(e.Row.Item) == (grid.Items.Count - 1))
           {
               grid.BeginInsert();
           }
       }

That way every time when you finish editing of a new row (by Enter or Tab buttons click), one more new row will be added.

Of course you may always use the Insert button to add a new row.

I have prepared a sample project, showing the described suggestion.

I'm trying to implement something similar with the newest release (Q2 '12) and when I do this I get an exception in the GridViewBoundColumnBase.GetValidationErrors().  It seems to be complaining that the "dataItem" (first parameter to the method) is null.  Any quick ideas, I'm guessing this has something to do with some changes to the GridView since june of last year.

Hello,

May I ask you to update the attached sample project with the change you have done? Does it work fine with our previous version?

This is the only change that I made:

RadGridView grid = sender as RadGridView;
if(grid == null)
    return;
if(grid.Items.IndexOf(e.Row.Item) == (grid.Items.Count - 1) && e.EditOperationType == GridViewEditOperationType.Insert)
{
    grid.BeginInsert();
}

The original code had this condition in the if(), which was always false for me (no matter what I did):

grid.SelectedItem == e.Row.Item

I added the condition check on the "E.EditOperationType" just to make sure this was only happening after a new row was already inserted.  I don't see how that could cause a problem.  The exception happens on the "grid.BeginInsert()" call.

I can't tell you if it worked with previous versions, this is the first time I've tried to do this. =)

Hello,

 Thank you for the code snippet. I have changed the project to use the suggested code together with the latest binaries. So far I was not able to encounter any problem.

Please find the changed project attached.
