为什么我无法获得CSS& jQuery在此GridView中有效果吗? [英] Why I could not be able to get the CSS & JQuery effects in this GridView?

问题描述

我正在尝试使用有关

I am trying to use this nice article about (Freezing GridView header and columns while scrolling rest of the content) in my project but I failed. I followed all the steps mentioned in the post but still I did not get it and I don''t know why.

I got the GridView with the data but without the CSS and JQuery effects. I got the symbol of error on the bottom left corner in the IE browser which says:

> Char: 9<br />
> <br />
> Error: ''0.offsetHeight'' is null or not an object<br />
> <br />
> Code: 0

此外，有时还会出现以下错误:

Also, sometimes it gives me the following error:

> Char: 11<br />
> <br />
> Error: Object doesn''t support this property or method<br />
> <br />
> Code: 0

***顺便说一句，当我删除ASP.NET代码中CSS风格下存在的内联JavaScript时，我没有得到该错误符号***
我的ASP.NET代码:

***And by the way, when I deleted the inline JavaScript that is existed below CSS style in the ASP.NET code, I did not get that error symbol***
My ASP.NET code:

                    </Columns>
                </asp:GridView>

在后面的代码中:

In the code-behind:

protected void Page_Load(object sender, EventArgs e)
   {

       //Repeater1.DataBind();
       GridView1.DataBind();
       GridView1.HeaderRow.TableSection = TableRowSection.TableHeader;

   }

推荐答案

(document).ready(function(){

(document).ready(function () {

(.tableDiv").each (功能 () { var ID =

(".tableDiv").each(function () { var Id =

(this).get(0).id; var maintbheight = 355; var maintbwidth = 760;

(this).get(0).id; var maintbheight = 355; var maintbwidth = 760;
