MasterPage - save value when user goes to other page

Hi

I'd think this would be simple. I have master page with checkbox.
When user navigates away from page1 using the MasterPage to another page using the same master page I want the checkbox to remain in same checked/unchecked state as it was before they navigated away. The snippet here shows where the checkbox is on master page.

Thanks in advance for help.

<asp:UpdatePanel runat="server" ID="HeaderUpdatePanel">
                <ContentTemplate>
 
....
 
                                                <asp:CheckBox runat="server" ID="IsAutoUpdateEnabled" Checked="false" AutoPostBack="true"  />
                </ContentTemplate>

Hi,

You will need to use a Session variable for this or a viewstate object to store the checkbox value and assign on each page to the checkbox.

thanks.

If you haven't already down so, set autopostback="true" and add an eventhandler for your checkbox. Below is an example of a persistent checkbox:

public partial class MasterPage : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Session["YourCheckBox"] != null)
{
dropdown.SelectedIndex = (int)Session["YourDropdown"];
}
}
}

protected void dropdown_CheckedChanged(object sender, EventArgs e)
{
Session["YourCheckBox"] = checkbox.SelectedIndex;
}
}
