GridViewComboBoxColumn commit issue

[Dharmavaram]

Hi,

 I have one column in RadGridview With combobox once I click on add new row , select a item  in combobox and click somewhere in grid the value is not committing .Only when I select other row or click on the row header it is committing.I want to commit my cell data once I lose focus from that cell.How to achieve it??

Regards,

Nagasree.

Hello Nagasree,

With a proper setup, it would be expected to save the value on focus lost by default. I have attached a sample project for your reference. Can you please share more information on your scenario? Do you use a RadComboBox within a CellTemplate or you use the GridViewComboBoxColumn implementation? Do you set the NewRowPosition of the RadGridView to add a new row?

Hi Stefan,

  In the sample application also the Datepicker will not commit even after I clicked in the empty space of the grid.It is committing only when I change selection to some other row or column.please fine the attached image files.

I want to commit and make cell to be in default once user goes out of the cell and click anywhere

Iam using RadGridview Combocolumn not the template.

Hello Nagasree,

Actually, such behavior is expected as the RadGridView is in edit mode and the values will be committed when the RowEditEnded event is fired. If you would like to commit the values when clicking on a field that is within the same row but does not present a cell that has a value, you can apply the following:

public MainWindow()
       {
           InitializeComponent();
           this.AddHandler(GridViewRow.PreviewMouseDownEvent, new RoutedEventHandler(onMouseDown));
       }

       private void onMouseDown(object sender, RoutedEventArgs e)
       {
           if ((e.OriginalSource as UIElement).ParentOfType<GridViewCell>() == null)
           {
               clubsGrid.CommitEdit();
           }
       }

Please give it a try in your actual application and update me if there are some issues.

I am sending the image of my grid.Actually I want a DataControl with Combobox.Here my workflow will be I have to select a value in a list from combobox Items. Once I select it should be committed because another grid will be updated with values based on the committed value in first grid.If the value in first grid is not committed when I try to edit in Second grid null reference exception is coming.

I should commit the value in the first list once we select value in combobox.Is there any alternate control which satisfy my purpose?

Any help is much appreciated as my completely blocked.

Hello Nagasree,

Would it be possible to provide a sample that shows your setup so we can provide more concrete answers? Generally, utilizing the LostFocus event is not recommended as the RadGridView uses it internally for some operations.
