Easiest way to implement popup window in ASP.NET


This tip demonstrates how to implement a movable Popup window in ASP.NET. A very important feature of this control is that it can be used on most of the current browsers. It has been tested with the latest version of Mozilla, Internet Explorer, and Opera.


Most of the time, developers face the problem in popup windows to automatically a hide popup window after a post back event because they use AJAX controls. In this tip, I provide you with an easy way to implement a popup window in ASP.NET without writing too much code.


On Page design

There is very little coding necessary to implement a popup control. First, you need to add DDL in your project. And register assembly in your page by using the following code:

<%@ Register Assembly="ASP.Web.UI.PopupControl" 
    TagPrefix="ASPP" %>  

After that, declare the control in the Page design (.Aspx). Whatever you want to show as popup, put into the PopupWindow tag in the following way:

<ASPP:PopupPanel HeaderText="This is Header" ID="pup" 
          runat="server" OnCloseWindowClick="MycloseWindow">
    <PopupWindow runat="server">
        <ASPP:PopupWindow ID="PopupWindow1" 
        Visible="false" runat="server">
            <asp:Label ID="lbl" runat="server">ssssssssss</asp:Label>
            <br />
            <asp:TextBox ID="txt" AutoPostBack="true" 
        <ASPP:PopupWindow ID="PopupWindow2" runat="server">
            <div align="center" style="width: 500px; height: 300px">
                <asp:Label ID="Label1" runat="server">nnnnn</asp:Label>
                <br />
                <asp:TextBox ID="TextBox1" AutoPostBack="true" 
                <asp:Button ID="in" runat="server" Text="sss" />
                <asp:TextBox ID="TextBox2" AutoPostBack="true" 

On code behind

For showing purposes, use:

protected void Button1_Click(object sender, EventArgs e)

For hiding purposes, use:

protected void Button2_Click(object sender, EventArgs e)


After closing, window click event is generated if you assign to OnCloseWindowClick in popup control:
