Answer 1

 GridViewRow gvrow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
 int index = gvrow.RowIndex;
         
           
string tNumber =GridView_projectTask.DataKeys[index].
Values["strProjectId "].ToString();

                {
                    Bind();
                }
            }
        }能不能像DataGrid里面一样 
用这样int strPropertyId = Convert.ToInt32(e.Item.Cells[0].Text);的语句代替？
因为对GridView不太熟悉！

Answer 4

可以在LINKBUTTON那里加上CommandName='<%#Eval("id")%>'属性，然后在后台e.CommandName获取ID值，把那些操作名都放进CommandArgument里面。我之前试过好像可以，只是一种方法啦！小弟也是新手，不好别喷！

Answer 5

那就这样写吧
GridViewRow gvrow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer); 
int index = gvrow.RowIndex; 
        
          
string tNumber =DVClientInfo.rows[index][2].tostring()

Answer 6

前台：<asp:LinkButton runat="server" ID="btnNext" Text="子类" CommandArgument="Next" CommandName='<%#Eval("ID") %>'></asp:LinkButton>后台：long parentId = long.Parse(e.CommandName);

Answer 7

还有就是你在前台控件那里加上datakey属性，并且设置为ID，也可以在后台绑定数据的时候，加上
this.gvData.DataKeyNames = new string[] { "ID" };gvData为你的控件名称，然后在后台
grdbank_ItemCommand时间里面：
 long id = long.Paese(this.gvData.DataKeys[e.RowIndex].Value)
看看能获取到不！

Answer 8

错误 37 无法将带 [] 的索引应用于“System.Web.UI.WebControls.GridViewRow”类型的表达式

Answer 9

少写了个  “.”
DVClientInfo.Rows [index ].Cells [2].tostring

Answer 10

CommandName=' <%#Eval("ID") %>' 这个属性我在别的事件中有用到不能改！最好不要改 CommandName=' <%#Eval("ID") %>'这个属性

Answer 11

方法一（可以获取gridview隐藏的列）
 在gridview中设置datakey  添加你要找的列
GridViewRow gvrow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer); 
int index = gvrow.RowIndex;    
string tNumber =GridView_projectTask.DataKeys[index]. 
Values["这是字段名"].ToString();方法二：
GridViewRow gvrow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer); 
int index = gvrow.RowIndex; 
        
string id=DVClientInfo.Rows [index ].Cells [2].ToString();够清楚了吧，我常用的就这2种
