Crazy Stupid: MessageBox in Asp.Net

This post shows how to create a message box using java script in asp.net pages.In windows application Message Box plays a important role in displaying information to users.But in asp.net pages there is no predefined Message Box Control so we create a alert box using using java script and information to the users.

Html Tag:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="AspTutor.WebForm1" %>

<!DOCTYPE html>

</head>

<body>

<div>

<asp:Label ID="lblName" runat="server" Text="Enter Text"></asp:Label>

<asp:TextBox ID="txtMessage" runat="server"></asp:TextBox>

<asp:button runat="server" text="Click" OnClick="Unnamed_Click"/>

<asp:button ID="btnException" runat="server" text="Exception" OnClick="btnException_Click"/>

</div>

</form>

</body>

</html>

Code Behind:

protected void Unnamed_Click(object sender, EventArgs e)

{

MessageBox(txtMessage.Text);

}

//Message Box

private void MessageBox(string Message)

{

StringBuilder sb = new StringBuilder();

sb.Append("<script>");

sb.Append("alert('");

sb.Append(Message);

sb.Append("')");

sb.Append("</script>");

ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", sb.ToString());

}

protected void btnException_Click(object sender, EventArgs e)

{

try

{

int j = 0;

int i = 1 / j;

}

catch (Exception ex)

{

MessageBox("Exception:" + ex.Message);

}
