排序在Gridview ASP.Net中不起作用 [英] Sorting is not working in Gridview ASP.Net

问题描述

大家好，



Arun。这次我在ASP.Net中有一个排序问题。对于第一次单击，降序工作正常但在第二次单击升序时不再进行。它仍然是降序。我使用Tableadapter来显示gridview内容。请查看代码并纠正我错过的地方。

  protected   void  gv1_Sorting（ object  sender，GridViewSortEventArgs e）
 {
 字符串 sdir = e.SortDirection == SortDirection.Ascending？   DESC：  ASC; 
 DataView dv =  new  DataView（ds2.AllocationPending（ClientLoggedIn.Text））; 
 dv.Sort = e.SortExpression +   + sdir; 
 gv1.DataSource = dv; 
 gv1.DataBind（）; 
} 

另外请解释 - 有没有其他方法可以在没有Dataview的情况下应用排序。



谢谢。

解决方案

原因是e.SortDirection总是返回Ascending .... br />
因此您需要将e.SortDirection存储在ViewState中并使用该值对数据视图进行排序...

以下是一些示例..

Hi All,

Its Arun. This time I have a sorting issue in ASP.Net. For the first click, descending is working fine but on the second click ascending is not taken again. Its still in the descending order. I m using Tableadapter to display the gridview content. Please review the code and correct me where I ve missed.

protected void gv1_Sorting(object sender, GridViewSortEventArgs e)
{
    string sdir = e.SortDirection == SortDirection.Ascending ? "DESC" : "ASC";
    DataView dv = new DataView(ds2.AllocationPending(ClientLoggedIn.Text));
    dv.Sort = e.SortExpression + " " + sdir;
    gv1.DataSource = dv;
    gv1.DataBind();
}

Also please explain - Is there any other way to apply sorting without Dataview.

Thank you.

解决方案

The reason is e.SortDirection always returns Ascending....
so you need to store the e.SortDirection in a ViewState and sort the dataview with that value...
Here are some samples..
