How to find the url of parent page of a User control

ascxasp.netuser-controlsweb-user-controls

I have a user control where if a certain action is performed I want to redirect to the page the user was on with some additional query string parameters.

So, if UserControl.ascx was on Home.aspx, I want to redirect to Home.aspx?action=true, and if UserControl.ascx was on Profile.aspx, I want to redirect to Profile.aspx?action=true

So basically, in my UserControl.ascx.cs I want to get the URL of the Parent Page. How can I get it?

You can look at the Request.Url, Request.RawUrl, Request.FilePath, and some of the other similar properties of the Request object - depending on how you're using this.

This will give you the requested URL from the browser, which will in turn tell you which page your control is living on.

C# – “The Controls collection cannot be modified because the control contains code blocks”

First, start the code block with <%# instead of <%= :

<head id="head1" runat="server">
  <title>My Page</title>
  <link href="css/common.css" rel="stylesheet" type="text/css" />
  <script type="text/javascript" src="<%# ResolveUrl("~/javascript/leesUtils.js") %>"></script>
</head>

This changes the code block from a Response.Write code block to a databinding expression.
Since <%# ... %> databinding expressions aren't code blocks, the CLR won't complain. Then in the code for the master page, you'd add the following:

protected void Page_Load(object sender, EventArgs e)
{
  Page.Header.DataBind();    
}

You do this via attributes on the properties, like this:

[Description("Test text displayed in the textbox"),Category("Data")] 
public string Text {
  get => myInnerTextBox.Text;
  set => myInnerTextBox.Text = value;
}

The category is the heading under which the property will appear in the Visual Studio Properties box. Here's a more complete MSDN reference, including a list of categories.
