數據綁定到網格嵌套在頁腳

Question

我在的RowDataBound附加編程按鈕頁腳：

else if (e.Row.RowType == DataControlRowType.Footer) 
    { 
     e.Row.Cells[1].Text = "Total: "; 
     e.Row.Cells[2].Text = totalStaff.ToString(); 
     Button showStaff = new Button(); 
     showStaff.CommandName = "ShowAll"; 
     showStaff.Text = e.Row.Cells[2].Text.ToString(); 
     e.Row.Cells[2].Controls.Add(showStaff); 
     e.Row.Cells[1].HorizontalAlign = HorizontalAlign.Right; 
     showStaff.Click += new EventHandler(showStaff_Click); 
    } 

現在我想處理showStaff_Click將數據綁定到嵌套GridView控件。我在RowCommand中編寫了bwlow代碼，但索引爲空：

  if(e.CommandName == "ShowAll") 
      { 
       int index = Convert.ToInt32(e.CommandArgument.ToString());     
       GridViewRow row = Staff.Rows[index]; 
       GridView StaffInfo = (GridView)Staff.Rows[index].FindControl("StaffInfo"); 
       int TeamID = 0; 
       int cityID = 3699; 
       StaffInfo.DataSource = GetStaff(cityID, TeamID); 
       StaffInfo.DataBind(); 
      } 

我將不勝感激您的幫助。

我名手一些變化：

protected void Staff_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    try 
    { 
     //Checking for command name which command/button is pressed 
     if (e.CommandName == "ShowDetails") 
     { 
      GridView Staff = (GridView)sender; 

      int index = Convert.ToInt32(e.CommandArgument); 
      GridViewRow row = Staff.Rows[index]; 
      GridView StaffInfo = (GridView)Staff.Rows[index].FindControl("StaffInfo"); 
      int TeamID = Convert.ToInt16(Staff.DataKeys[index].Values[0].ToString()); 
      int cityID = Convert.ToInt16(Staff.DataKeys[index].Values[1].ToString()); 
      StaffInfo.DataSource = GetStaff(cityID, TeamID); 
      StaffInfo.DataBind(); 
      StaffInfo.Visible = true; 
     } 
     else if(e.CommandName == "ShowAll") 
     { 
      int index = Convert.ToInt32(e.CommandArgument); 
      GridView StaffInfo = (GridView)Staff.Rows[index].FindControl("StaffInfo"); 
      int TeamID = 0; 
      int cityID = 3699; 
      StaffInfo.DataSource = GetStaff(cityID, TeamID); 
      StaffInfo.DataBind(); 
      StaffInfo.Visible = true; 
     } 
    } 
    catch (Exception ex) 
    { 
     Response.Write(ex.Message); 
    } 
} 

<asp:GridView ID="Staff" runat="server" AutoGenerateColumns="false"

    </asp:TemplateField> 
</Columns>  

當我嘗試點擊勾住ShowAll按鈕伊特返回指數超出範圍。我做了Response.Write（intex.ToString（）），它返回-1。情況或行中的索引號被正確返回。問題在於頁腳按鈕。你可以幫我嗎？

Answer 1

當您按下按鈕時，您沒有設置CommandArgument。

Button showStaff = new Button(); 
showStaff.CommandName = "ShowAll"; 
showStaff.CommandArgument = e.Row.RowIndex.ToString(); 
showStaff.Text = e.Row.Cells[2].Text.ToString();
