I'm using dataTable load data from database, binding this datatable to datasource of gridview. And i'm using "Right Click" to select "delete row". And this row has been deleted on GridView. Now i want after "delete row" it will delete this row on GridView and it will delete this item on database.

I don't known Event ocurr when delete this row. Please give me that event

I have a similar query

When deleting a row of the grid, I would like to capture the event, query the row, and then inform another object that this row has been deleted.

The problem is I cannot find a method such as userDeletingRow as available in the MS grid.

Hi Sasa,

We have just replied to your support ticket on the matter.

Currently we are not providing an event for the delete operation. This feature will be included in our Q2 release. What you can do is use the IBindingList ListChanged event if your bound objects support the IBindingList interface.

But you can do something like this:

        private void dataGridViewMain_RowsChanging(object sender, GridViewCollectionChangingEventArgs e)

        {

            if (e.Action == Telerik.WinControls.Data.NotifyCollectionChangedAction.Remove) 

            { 

                DialogResult dialogResult = MessageBox.Show("Do you want to delete this product?", "Warning", MessageBoxButtons.OKCancel, MessageBoxIcon.Question); 

                if (dialogResult != DialogResult.OK) 

                {

                    e.Cancel = true; 

                } 

            }

        }

and add your code to update data in data base :).

Hi ,

In Q2 2010 release we introduced UserDeletingRow and UserDeletedRow events. You can use them in your scenario.
