推荐答案

您做错了.从LinkButton中删除oncommand .

将OnRowCommand事件添加到GridView.

You are doing it wrong. Remove the oncommand from LinkButton.

Add a OnRowCommand Event to the GridView.

<asp:GridView ID="grdBindData" runat="server" CssClass="mGrid" AutoGenerateColumns="false" DataKeyNames="id, invoiceno" EmptyDataText="NO DATA FOUND" OnRowCommand="grdBindData_RowCommand" >

在类似...的后面代码中添加事件.

Add the event in code behind like...

protected void grdBindData_RowCommand(object sender, GridViewCommandEventArgs e)
{
    btnsave.Text = "UPDATE";
}
