Question

我想删除网格视图中的行，这是我在rowcommand中的后端代码。我已经在函数中创建了一个OnRowDeleting但没有任何内容。

protected void grid2_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            switch (e.CommandName) // check the incoming command name
            {
case "remove":
                    if (grid2.Rows.Count > 1)
                    {
                        int rowIndex = Convert.ToInt32(e.CommandArgument);
                        //GridViewRow row = (GridViewRow)grid2.Rows[rowIndex];
                        grid2.DeleteRow(rowIndex); //error pointing to this
                        grid2.DataBind();
                    }
                    else
                    {
                        Page.ClientScript.RegisterStartupScript(this.GetType(), "Scripts", "
<script>alert('Last row');</script>");
                        }
                        break;
    }

我的前端代码

 <ItemTemplate>
 <asp:Button ID="BtnDelete" runat="server" Text="Delete" 
 CssClass="btn btn-primary" CommandName="remove" CommandArgument='<%# Container.DataItemIndex %>'/>
 </ItemTemplate>

当我点击删除按钮

时出现此错误

类型＆＃39; System.NotSupportedException＆＃39;的例外情况发生在   System.Web.dll但未在用户代码中处理

其他信息：数据源不支持删除   ＆＃39; SqlDataSource2＆＃39;除非指定了DeleteCommand。

数据源

 <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ConnStr_epsi %>" 
                             ProviderName="<%$  ConnectionStrings:ConnStr_epsi.ProviderName %>" SelectCommand=""></asp:SqlDataSource>

我的网格

 <grd:MultiSelectGridView ID="grid2" runat="server" Width="500px" 
                        CssClass="paging_gridview" AllowPaging="True" 
                        AutoGenerateColumns ="false" PageSize="10" PagerType="Custom"  
                        ShowFooter="true" OnRowDeleting="grid2_RowDeleting" 
                        MultiSelectDataKeyName="Urid,Name" ShowHeaderWhenEmpty="true"
                        MultiSelectColumnIndex="0" EnableMultiSelect="false" GridLines="None" BorderStyle="None"  OnRowCommand="grid2_RowCommand"
                        >

删除gridview中的行会收到错误
