Hi,

This example demonstrates how to handle the events of an element. You can change it to be used on a DataCell rather than a DataRow. Note that the sender will be the element and can be cast as such.

If you have the DataRow, you can get the cell from its Cells collection. If you have the cell, you can access its content through its Content property. 

Hi,

You can do like that:

1. handle an event in Xceed grid (for example: I handle MouseDoubleClick event)

2. Use this code ()

        private void dgPart_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            DataGridControl dataGridControl = sender as DataGridControl;
            if (dataGridControl != null)
            {
                Row row = (Row)dataGridControl.GetContainerFromItem(dataGridControl.CurrentItem);
                Cell currentCell = row.Cells[dataGridControl.CurrentColumn.Index];
                if (currentCell != null && currentCell.HasContent)
                {
                    // Get value here
                }
            }
        }

Hope to help you
