Hello,

How can I make the first row of a RadgridView selected by default, if there's any?

Thank You.

Hi Luis,

Actually, the first row of RadGridView is selected by default. Still, you can use the code below to programmatically select rows:

    
            this.radGridView1.Rows[0].IsSelected = true;

Feel free to contact me if you have further questions.

Kind regards,

Sorry for the ressurection of this topic but I need some precision about it.

The first row of a RadGridView is certainly selected by default when the databinding is done.

But if you have set some sort descriptor before (on design as an exemple), it look like the selection of the first row is done before sorting. So the "first selected row" move in a random place if the datasource is not sorted the same way as your descriptor before binding.

I don't think it's a good idea to rely on the fact that your datasource order is the same of the grid because you could be sure that one day somebody will change only one of them and the random selected row effect will come back.

What's the position of Telerik on this behavior ?

Hello Marco,

RadGridView's CurrentRow will be set to the row according to the form's CurrencyManager's Position property. So, when you assign a DataSource to the grid, the Form's CurrencyManager will know about this source, and its Position defaults to 0. Then, when you sort the grid, this Position (and the grid's CurrentRow) is not changed, which is desired and expected.

However, you can easily change the CurrentRow, by simply setting this property of the grid to any of its rows. For example in your case you can use the DataBindingComplete event:

void radGridView1_DataBindingComplete(object sender, GridViewBindingCompleteEventArgs e)

{

radGridView1.CurrentRow = radGridView1.Rows[radGridView1.Rows.Count - 1];

}

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
