How to hide a div from code (c#)

Question

I have a div element on my page that I wish to show/hide based on a session value in my code-behind. How can I do this?

Answer 1

work with you apply runat="server" in your div section...

<div runat="server" id="hideid">

On your button click event:

 protected void btnSubmit_Click(object sender, EventArgs e)
    {
      hideid.Visible = false;
    }

Answer 2

one fast and simple way is to make the div as

<div runat="server" id="MyDiv"></div>

and on code behind you set MyDiv.Visible=false

Answer 3

Try this. Your markup:

<div id="MyId" runat="server">some content</div>

.. and in aspx.cs file:

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["someSessionVal"].ToString() == "some value")
    {
        MyId.Visible = true;
    }
    else
    {
        MyId.Visible = false;
    }
}
