asp。 .NET pops up a dialog box from the server to the client, the page turns white, and the layout changes The solution is to add this function to the CS class:

/// <summary>
      A dialog box pops up
      /// </summary>
      <param name="page"> the page to pop up the dialog box, this page uses this. Page</param>
      <param name="values"> what pops up</param>
      public void WebMessageBox(System.Web.UI.Page page, string values)
      {
         page. Clientscrip removes t.RegisterStartupscrip removes t(page. GetType(), "", "<scrip remove t language=javascrip remove t>alert('" + values + "')</scrip去掉t>");
      }

You can call this function when using it, as follows:

if (string. IsNullOrEmpty(strTemp))
         {
            sc = new StrControl();
            sc. WebMessageBox(this. Page, "Search content cannot be empty");
         }

This way, there will be no whitening of the page and invalidation of CSS styles.

Reason: Because the source code of the page is written like this, the following sentences are added at the end of the page:

<scrip remove t language=javascrip remove t>alert('Search content cannot be empty').</scrip去掉t></form>
</body>
</html>

Here's a way to fix page whitening, but the CSS styles break and the result is as follows because the generated page source code is at the very top of the page:

1. Background code
if (string. IsNullOrEmpty(strTemp))
         {
            Response.Write("<scrip remove t >function window.onload() {alert('Search cannot be empty!'); }</scrip去掉t>");
         }

2. Front desk code
<scrip remove t >function window.onload() {alert('Search page cannot be empty!'); } }</scrip去掉t>

<scrip remove t src="../scrip remove ts/jquery-1.7.2.min.js" type="text/javascrip remove t"></scrip去掉t>
<scrip remove t src="../scrip remove ts/Default.js" type="text/javascrip remove t"></scrip去掉t>
</head>
