ASP.NET

when you are binding the values from any source, create another alias in your selection query.

ex: select fullname,left(fullname,20) as shortname from tablename

the 20 mentioned can be of your need.and then bind the shortname to literal.it works.

<ItemTemplate>
 <asp:CheckBox ID="chkItemSelect" runat="server" />
 <asp:Label ID="lblname" Text='<%#Bind("name")%>' runat="server" />              
<asp:Button ID="btnFindx" runat="server" CommandName="Findx" Text="Do Some thing" CommandArgument='<%#Eval("ID")%>'></asp:Button>
                                        </ItemTemplate>

Protected Sub GridView_RowCommand(sender As [Object], e As GridViewCommandEventArgs)
	Select Case e.CommandName
		Case "Findx"
			MethodFindControlValue()
			Exit Select
	End Select
End Sub

Private Sub MethodFindControlValue()
	For Each row As GridViewRow In ApprovalGrid.Rows
		Dim chkItemSelect As CheckBox = CType(row.FindControl("chkItemSelect"), CheckBox)
		Dim chkItemSelect As Label = CType(row.FindControl("lblname"), CheckBox)

		Dim id As String = Convert.ToString(NameGridView.DataKeys(row.RowIndex).Value.ToString())
	Next
End Sub
