Hi.
I have an question about the focus of Cell.
Immediately after adding a new line, It does not work, although he would like to move the focus of Cell to the specified column of added line.
For example, item will be null in The following codes.
(at Button1_Click method)
radGridView.UnselectAll();
radGridView.SelectedItem = radGridView.Items[insertingRowIndex];
radGridView.CurrentItem = radGridView.Items[insertingRowIndex];
var m_ColumnIndex =1;
var item = (GridViewRow)radGridView.ItemContainerGenerator.ContainerFromIndex(insertRowIndex);
// item is null
item.Cells[m_ColumnIndex].Focus();
// NullReferenceException
Version:
Telerik RadControls for WPF 2010 Q1 309 Trial
Visual Studio:2010 RC
Please help me.
Regards,
athasian.

Hello athasian,
Indeed GetContainerFromIndex() method may return null in some cases.
My guess is that you do not want just to set focus of the cell, but also you want to put it in edit mode.
I'm attaching sample project that demonstrates how to do this. After starting of the application click somewhere in the grid and press Insert key. Let me know if this doesn't help, but I will need some more detailed information about your scenario (type of the data source and type of the business object and all information that you can find useful).
Sincerely yours,
