在asp.net中单击按钮时显示div

Question

I want to display a particular div on the click of a button
My asp code is as follows

<asp:Button ID="Button1" class="btn" runat="server" OnClick="Submit" />

<div runat="server" id="signup" Visible="false">Some Content </div>

Now in the CodeBehind i have written the following code

protected void Submit(object sender, EventArgs e)
    {
        Button1.Visible = false;
        signup.Visible = true;
    }

But every time i get the error as

the name signup does't exist in the current context

i am not able to figure out the problem in the code..

Answer 1

You probably have wrong html for the div , you can also use style="visible:none" instead of Visible="false"

Change

visible:"false" 

To

Visible="false"

Answer 2

This has to be done through JavaScript, I believe in the onClientClick attribute of the button. I'm currently searching for the code to jog my own
