Question

<Columns>
                <asp:BoundField />
                <asp:HyperLinkField DataTextField="fenxiangzhibiao_cn" HeaderText="分项指标" >
                </asp:HyperLinkField>

                <ItemTemplate>
                <asp:TextBox ID="Tbshijishu" runat="server"  Width="100px"  ReadOnly="false"></asp:TextBox>
                <asp:Button ID="Button1" runat="server" Text="Button" CommandArgument='<%# Eval("fenxiangzhibiao_cn")+","+Eval("Tbshijishu的值？？")  %>' />
                 </ItemTemplate>
                </asp:TemplateField>
                 </Columns>各位，我想点击对应行Button 的时候把填入Tbshijishu的值传到后台，CommandArgument=什么呢？

Answer 1

GridViewRow drv=((GridViewRow)(((Button)(e.CommandSource)).Parent.Parent));
string aa=GridView的ID.Datakeys[drv.RowIndex].Value;
Response.write(aa);
你在GridView的的属性中把Datakeys设置成你要传的字段名 

Answer 2

我要传的参数是用户填入到模板列TextBox中的值，不是绑定的列哦，这样行吗

Answer 3

  <asp:Button ID="Button1" runat="server" Text="Button" CommandArgument='<%# Eval("Tbshijishu的值？？") %>' />后台
 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            
            if (e.CommandName == "Btn")
            {
                Response.Redirect("url.aspx?" + e.CommandArgument);
            }
        }

Answer 4

<asp:Button ID="Button1" runat="server" Text="Button" CommandArgument='<%# Eval("Tbshijishu的值？？") %>' CommandName="Btn" />后台
 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
  {
    
  if (e.CommandName == "Btn")
  {
  Response.Redirect("url.aspx?" + e.CommandArgument);
  }
  }

Answer 5

CommandArgument='<%#Eval(" ")%>'
if (e.CommandName == "")
  {
  // e.CommandArgument.ToString();
}或GridViewRow gvr = (sender as Button).NamingContainer as GridViewRow;   
TextBox txt=gvr.FindControl("txt") as TextBox;
多值CommandArgument= ' <%#   Eval( "Field1 ")   +   ", "   +   Eval( "Field2 ")   %> '
