Grid VIew的OnRowDataBound事件 [英] OnRowDataBound event of Grid VIew

问题描述

你好先生，



我有一个数据库，有一个表有两列（Name，Id）。我编写了一个代码来自定义网格视图的排序。请参阅以下代码：

Hello Sir,

I have a database with a table it has two columns (Name,Id). I wrote a code to customize the sorting for a grid view. Please see the below code :

<asp:GridView ID="gv1" DataSourceID="sql1" AutoGenerateSelectButton="true" DataKeyNames="Name,Id" AllowSorting="true" CssClass="gridview" SelectedRowStyle-CssClass="selectedRow" OnRowDataBound="rowdatabound" runat="server" />
  <asp:SqlDataSource id="sql1" runat="server"  SelectCommand="select * from contact" ConnectionString="Data Source=.\SQLEXPRESS;AttachDBFileName=|DataDirectory|Database1.mdf; User Instance=True; Integrated Security=True"/>

守则背后是：

The Code Behind is :

public void rowdatabound(object sender, GridViewRowEventArgs e)
      {
          if (e.Row.RowType == DataControlRowType.Header)
          {
              foreach (TableCell cell in e.Row.Cells)
              {
                  LinkButton sortlink = (LinkButton)cell.Controls[0]; -------1
                  if (sortlink.Text == gv1.SortExpression)
                  {
                      if (gv1.SortDirection == SortDirection.Ascending)
                      {
                          sortlink.Text = "Ascending";
                      }
                      else
                      {
                          sortlink.Text = "Descending";
                      }

                  }

              }

          }

      }

但我得到的错误是第1行的索引超出范围。

嗨Rahul，



试试这个代码。

Hi Rahul,

Try this code.

DataControlFieldHeaderCell sortlink = (DataControlFieldHeaderCell)cell;

您的代码无法正常工作的原因b'coz您已打开

The reason your code in not working properly b'coz you have turned on

AutoGenerateSelectButton="true"

。



如果你删除

.

If you remove

AutoGenerateSelectButton="true"

您现有的代码将完美运行，我的意思是没有任何错误或例外。



希望这会有所帮助！

your existing code will work perfectly, I mean without any errors or exceptions.

Hope this helps!
