Displaying the value of a string variable in ASP.Net markup

Is it possible to take the value from a string variable from a code-behind file and display it in this markup?

<h1>People Authorized to Release Children for <TheVariableGoesHere>  </h1>

The variable we would like to include is called strForename.

Protected Sub GridViewParentsSummary_SelectedIndexChanged(sender As Object, e As EventArgs) Handles GridViewParentsSummary.SelectedIndexChanged

    IntParentsID = GridViewParentsSummary.DataKeys(GridViewParentsSummary.SelectedIndex).Value
    strForename = GridViewParentsSummary.DataKeys(GridViewParentsSummary.SelectedIndex).Values("Forename")

    blnAddModeIsSelected = False

    Response.Redirect("AuthorizationForChildReleaseDetails.aspx")

End Sub

You can do this by making your variable protected or public member and using it in the markup like this:

<%#strForename%> Make sure to call DataBind so the field is bound. I see that you are doing a redirect at the end of your function, You cannot use the variable from page 1 into a redirected page unless you pass it somehow (as a Request parameter or session parameter) Alternatively you can do a Server.Transfer and pass that in the context

The way this would be accomplished is through a code behind method being called.

Something like this for C#

<h1>People Authorized to Release Children for <% =this.GetForename() %> </h1>

or this for VB.NET

<h1>People Authorized to Release Children for <% =Me.GetForename() %> </h1>

and in code behind C#

protected string GetForename() 
{
    return GridViewParentsSummary.DataKeys(GridViewParentsSummary.SelectedIndex).Values("Forename");
}

or in VB.NET

Protected Function GetForename() As String
    Return GridViewParentsSummary.DataKeys(GridViewParentsSummary.SelectedIndex).Values("Forename")
End Function
