Hi Gary,
As for the Wizard control, those different Container (such as Navigation
Panel , SideBar Panel...) , they're separate from each other (under the
Wizard control's Sub control colleciton). Therefore, if you want to lookup
any child control within any of them, you need to get reference to the
certain container first. Generally, a useful means to determine the
control structure/hierarchy is turn on page's output trace (see the
below
directive):
=====================
<%@ Page Language="C#" AutoEventWireup="true"
CodeFile="CSWizard.aspx.cs"
Inherits="CSWizard"
Trace="true" %>
==================
And based on my test, the "Navigation container"'s control ID is
"StepNavigationTemplateContainerID". You can use it to get the Navigation
container control first, and call FindControl on it to get the
"MovePreviousButton" and "MoveNextButton".
here is a simple test page I've used. Also, "ActiveStepChanged" event
is
not the proper event to lookup control collection (because at that time,
the new Step's control collection hasn't been populatd yet). I suggest you
use "Load" event.
=============aspx template ======
<asp:Wizard ID="Wizard1" runat="server" ActiveStepIndex="1"
onactivestepchanged="Wizard1_ActiveStepChanged"
onload="Wizard1_Load">
<WizardSteps>
<asp:WizardStep runat="server" title="Step 1">
<asp:Label ID="Label1" runat="server"
Text="Label1"></asp:Label>
<br />
<asp:Button ID="Button1" runat="server"
Text="Button1"
/>
</asp:WizardStep>
<asp:WizardStep runat="server" title="Step 2">
<asp:Label ID="Label2" runat="server"
Text="Label2"></asp:Label>
<br />
<asp:Button ID="Button2" runat="server"
Text="Button2"
/>
</asp:WizardStep>
<asp:WizardStep runat="server" Title="Step 3">
<asp:Label ID="Label3" runat="server"
Text="Label3"></asp:Label>
<br />
<asp:Button ID="Button3" runat="server"
Text="Button3"
/>
</asp:WizardStep>
<asp:WizardStep runat="server" Title="Step 4">
<asp:Label ID="Label4" runat="server"
Text="Label4"></asp:Label>
<br />
<asp:Button ID="Button4" runat="server"
Text="Button4"
/>
</asp:WizardStep>
</WizardSteps>

<asp:Button ID="StepPreviousButton" runat="server"
CausesValidation="False"
CommandName="MovePrevious" Text="Previous" />
<asp:Button ID="StepNextButton" runat="server"
CommandName="MoveNext"
Text="Next" />
</StepNavigationTemplate>
</asp:Wizard>

Subject: Accessing Wizard Next/Prev buttons
Date: Thu, 26 Jun 2008 10:59:43 -0600
I have a Wizard page and need to affect the next and previous buttons from
my code-behind. I've googled around and found two solutions, and
neither
appear to work.
I can access the SideBarList steps successfully with the following code...
Control myContainer =
(Control)Wizard1.FindControl("SideBarContainer");
DataList mySideBarList =
(DataList)myContainer.FindControl("SideBarList");
mySideBarList.Enabled = false;
Trying to take this approach with the StepNavigationTemplate does not seem
to work. I first converted the step navigation to a template but I cannot
get findcontrol to find anything in "StepNavigationContainer" or
"StepNavigationTemplate" or anything else I can think of.
I have also tried putting .hidden {display:none} in my .css file and
....
protected void Wizard1_ActiveStepChanged(object sender, EventArgs e)
{
if (Wizard1.ActiveStepIndex == 3)
{
Wizard1.StepPreviousButtonStyle.CssClass = "hidden";
Wizard1.StepNextButtonStyle.CssClass = "hidden";
}
}
This has the effect of not working when goint to step 3 as the Prev/finish
still show. However if the prev button is hit, step 2 shows with the next
button not visible.
Is there a solution to this problem? Is there a reliable way to access
these buttons?
Thanks,
Gary
