How can I catch the double click on the row and its value?

If it’s a row without cells, you can catch the DoubleClick-event of the row itself. If it’s a row with cells (CellRow, ValueRow, DataRow, …), you have to catch the DoubleClick-event of the individual cells, like this:
<code>
foreach(Xceed.Grid.Cell cell in row.Cells) cell.DoubleClick += new EventHandler(CellDoubleClick);
private void CellDoubleClick(object sender, EventArgs e)
{
Xceed.Grid.CellRow row = (sender as Xceed.Grid.Cell).ParentRow;
}
</code>

I am also having same problem. Following are the Tommy’s code which I converted to VB.NET:

Dim cell As Xceed.Grid.Cell
For Each cell In <u>Row.Cells</u>
cell.DoubleClick = New EventHandler(CellDoubleClick)
Next

Private Sub CellDoubleClick(ByVal sender As Object, ByVal e As EventArgs)
Dim row As Xceed.Grid.CellRow = (sender)
‘as Xceed.Grid.Cell.ParentRow
End Sub

There is a problem in the underlined code. how can I refer the cells here?

I don’t understand the problem. Perhaps VB.NET has problems with indexers, collections and foreach.
Here is the code in VB.NET (untested):

‘ row is the Xceed.Grid.CellRow you want to detect double-clicks from
Dim cell As Xceed.Grid.Cell
Dim i As Integer
For i = 0 To row.Cells.Count – 1
AddHandler row.Cells.Item(i).DoubleClick, AddressOf CellDoubleClick
Next

Private Sub CellDoubleClick(ByVal sender As Object, ByVal e As EventArgs)
Dim cell As Xceed.Grid.Cell
Dim row As Xceed.Grid.CellRow
cell = CType(sender, Xceed.Grid.Cell)
row = CType(cell.ParentRow, Xceed.Grid.Row)
End Sub

i get error here:

For i = 0 To <u>row.Cells.</u>Count – 1

row is just an example, it’s not an existing property. It should be defined as an Xceed.Grid.CellRow (including DataRow and ValueRow).

Stilll trying to access the row & cell object….

myGrid.BeginInit()
Dim row As Xceed.Grid.CellRow = myGrid.CurrentRow
MsgBox(row.Cells.Count)
myGrid.EndInit()

following error occured with the above code:

Ojbect reference not set to an instance of an object.

if i could solve this problem, i may be able to workaround the cells.

Before trying to get the Cells-property, check if row is not Nothing (null in C#).

I found the answer at last.

‘adding event handler in form load
Dim cell As DataCell
For Each cell In mygrid.DataRowTemplate.Cells
AddHandler cell.DoubleClick, AddressOf Me.Cel_DoubleClick
Next cell

Private Sub Cel_DoubleClick(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles mygrid.DoubleClick
Dim cell As Cell = CType(sender, Cell)

‘parentRow’s property can be used to access the rows value
Dim parentRow As CellRow = cell.ParentRow
End Sub
