Question

我有一个带有Label控件的列，它将Count保存在嵌套在Repeater中的Gridview中。如果有3个Gridview显示，每个5行，我如何继续Gridview的RowDataBound事件中的编号？目前，当我使用

时，Gridview重新开始

(e.Row.FindControl("lblCount") as Label).Text = (e.Row.RowIndex +1).ToString();

当前结果：
Gridview1
1
2
3
4
5

Gridview2
1
2
3
4
5

Gridview3
1
2
3
4
5

期望结果：
Gridview1
1
2
3
4
5

Gridview2
6
7
8
9
10

Gridview3
11个
12个
13个
14个
15

.aspx.cs

protected void gvProposals_RowDataBound(object sender, GridViewRowEventArgs e){
if(e.Row.RowType == DataControlRowType.DataRow)
{
  (e.Row.FindControl("lblCount") as Label).Text = (e.Row.RowIndex+1).ToString();
}
}

在事件处理程序之外定义计数器，在Page_Load之后的public partial class...处理程序之前的好地方：

private int counter;

在RowDataBound事件处理程序中：

protected void gvProposals_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
        {
            counter++;
            (e.Row.FindControl("lblCount") as Label).Text = counter.ToString();
    }
}

ASP.NET C＃在Repeater
