How to display a msgbox in asp.net using C#?
I can't do it using windows.msgbox
It can be done by,

Response.Write("<script>alert('Item Already Exists')</script>");

But the problem I am facing is that, when the msgbox is being displayed, the actual webpage turns blank (i.e. full white), and on clicking OK, I am getting back the page again. Is there any way to display the msgbox as well as the page at the same time?

This is because you are invoking it from C#. What you could do is use jQuery and use the document.ready() function so that it fires when the page has finished loading.

{
  string message = "Hello! Vinod.";
  
  ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", message);
}

You have to add reference of using " system.windows.forms " to use messagebox.show feature.
It very simple.

The messagebox would be displayed on the server computer not on the client side for the user to see. What would be the point of that?

Well try with:

ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + myStringVariable + "');", true);

Aritra Nath 7-Sep-12 16:36pm

You cant do Response.Write since it wipes out the content and put the response as what you are sending inside the Write method.

Instead lets say you have a button in your asp.net page and on click of the button you want to show the message box from C# then,You can do this on the button click event in C#

C#

string javaScript = "alert('Item Already Exists');";


          Page.ClientScript.RegisterStartupScript(this.GetType(),"ButtonClickEventScript", javaScript,true);

This is because the script which aligns the menu gets executed after our alert script gets executed. That is always the problem with RegisterStartupScript since it doesn't guarantee order.

Aritra Nath 8-Sep-12 1:02am

so any idea on how to fix this?? or is there any other way to display the msgbox so that the menu alignment stays intact??

Ashraff Ali Wahab 8-Sep-12 16:55pm

Call the javascript function which aligns the menu before calling this alert statement.
