I'm wondering how I could update the querystring of my URL each time I hit the Next button of a Wizard control in order to show the ActiveStepIndex.
Example:
Really you probably want to do this when the Active Step changes under any circumstances.
Add a handler for OnActiveStepChanged in your .aspx page:
<asp:Wizard ID="NewWizard" runat="server" ActiveStepIndex="0" OnActiveStepChanged="Wizard_OnActiveStepChanged">
<WizardSteps>
...
</WizardSteps>
</asp:Wizard>
Then, implement your handler:
protected void Wizard_OnActiveStepChanged(object sender, EventArgs e)
{
Request.QueryString.Set("Step",Convert.ToString(NewWizard.ActiveStepIndex));
}
This should work, however I haven't tested this code so I cannot make any kind of guarantee that it will work.
It complaints about Request.QueryString saying: "Collection is read-only."
I just found out how to handle this situation.
In HTML:
<body id="body" runat="server">
In code-behind:
protected void wizard_OnActiveStepChanged(object sender, EventArgs e)
{
body.Attributes.Add("onload", "document.location.hash = 'Step" + wizard.ActiveStepIndex + "';");
}
