How do you get the contents of a given cell when it is clicked on?

Code: 
Dim dg As DataGridItem
dg = e.Item

dg.Attributes.Add("onclick", "getCellData('" & [???] & "')")

......

function getCellData(s){
	alert(s)
}

What do I substitute for the [???] in the example above?

If you are adding the attributes in the ItemDataBound you can use e.Item.Cells(0).Text to get the text of a particular cell.

Thanks. Ok. The e.Item.Cells(0).Text gives me the contents of the first cell in the selected row.

What I need to get is the selected column. How do I get the contents of the cell that the user clicked?

If I could get it to return the index of the column that the user clicked, that would also work. But if I hard code an index number in the Cells(?) it will only return me the value that is in that cell and not the one the user clicked on.

If you perform this operation in the OnItemCommand of the DataGrid it will return the value from the row that was clicked. If you want a primary key or index returned you can bind it to the grid as a BoundColumn Visible="False" and retrieve the value that way (using the above method) or, you can add the primary key column to your grid as a DataKeyField (in Properties) and retrieve it that way by going after e.Item.ItemIndex (
