在您的C#页面中,您可以编写if语句吗?

试试这个 -

if (ID == "Button2") { Response.Redirect("http://yourDestination?"); }

答案 1 :(得分:0)

您可以使用LinkBut​​ton而不是按钮,并使用此问题中的命令: How to get selected row field from gridview in asp.net 我想这可以帮到你。

答案 2 :(得分:0)

我假设您将gridview行Index作为参数传递 ,使用<%# Container.DataItemIndex%>获取gridview的行索引,使用ButtonCode,如

 <asp:Button ID="Button2" runat="server" CommandArgument="<%# Container.DataItemIndex %>" CommandName="nav" Text="Browse" CssClass="btn" />

记住行索引总是从0开始,如果你想从1

那么使用<%# Container.DataItemIndex + 1 %>

- &GT;在GridView中添加OnRowDataBound方法 - &GT;和C#中的代码。

protected void GridView1_RowDataBound(object sender,GridViewRowEventArgs e)
   {
       if(e.Row.RowType == DataControlRowType.DataRow)
        {
           if(Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem,“ID”))&gt; 0)
            {
          的Response.Redirect(链路);
            }

    }
}
