AddHandler Me.ChartOppLoc2.Click, AddressOf ChartOppLoc_Click
However this does not work on IE7/8. Works with FF and Opera. The pointer cursor is there and the link says "javascript:__doPostBack('LegendClick/0',''ChartOppLoc2)" which is also correct.
I debug and it doesn't go to the function at all. This functionality has always worked fine till now. the only difference now is i use some ajax methods from coolite. However this is not directly related to the chart in any way. Really got me confused. Before using ajax methods i tried using this code : coolite.GridPanel.AddScript("javascript") which also caused the issue. I need to note that postback works without ajax method. The ajax method is used for showing/hiding the coolite panel.
some HTML:
<ext:Tab ID="TabOppLoc2" Enabled="false" runat="server" Title="Opportunity Locator 2" >
<Body><br />
<asp:Chart ID="ChartOppLoc2" runat="server" >
...
Some aspx.vb code
<AjaxMethod()> _
Public Sub swapCodes()
'enable/disable opp locator tab 2
If radioData17.Checked = True Then
TabOppLoc2.Enabled =
False
Exit Sub
Else
TabOppLoc2.Enabled =
True
Exit Sub
End If
...
' Add custom legend item with image England
Dim legendItem = New LegendItem()
legendItem.BackImageTransparentColor = Color.White
legendItem.Cells.Add(LegendCellType.Image, "images/radio_button_unchecked.gif", ContentAlignment.MiddleCenter)
legendItem.Cells.Add(LegendCellType.Text, "Mean England", ContentAlignment.MiddleLeft)
ChartOppLoc2.Legends("LegendQOF3").CustomItems.Add(legendItem)
ChartOppLoc2.Legends("LegendQOF3").CustomItems(1).Cells(0).ImageTransparentColor = Color.Black
...
Any ideas are greatly appreciated. Thank you
