插入網格行上的OnClick事件並按照選擇打開新網格

Question

下面您可以找到我的網格代碼，並且每個事物都可以正常工作。現在我想在RegionProjectname上添加Click事件，以便當我點擊Region項目名稱行時，該列的RegionProjectID存儲在會話變量中，並且將根據選定的行打開新的網格。請編輯或指導我如何做到這一點。

我已經添加在網格中的選擇行，也工作正常，但我評論。

Answer 1

你好，你可以嘗試使用此代碼

1. Firslty在列添加ButtonField字段

   <asp:buttonfield buttontype="Link" commandname="Add" text="Add"/> 
   

2. 添加事件GridView_RowCommand

   void GridView_RowCommand(Object sender, GridViewCommandEventArgs e) 
   { 
        if(e.CommandName=="Add") 
        { 
         int index = Convert.ToInt32(e.CommandArgument); 
   
         GridViewRow row = ContactsGridView.Rows[index]; 
   
   
         Session["YourKey"] = ...; 
        } 
   
   }
