刪除GridView中的行獲取錯誤

Question

我想在網格視圖中刪除行，這是來自rowcommand的后端代碼。 而且我已經創建了OnRowDeleting，但是函數中什么也沒有。

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;
    }

我的前端代碼

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

單擊刪除按鈕時出現此錯誤

System.Web.dll中發生類型'System.NotSupportedException'的異常，但未在用戶代碼中處理

附加信息：除非指定DeleteCommand，否則數據源'SqlDataSource2'不支持刪除。

數據源

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

我的網格

 <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"
                        >

Answer 1

您必須將CommandName設置為“刪除”，例如插入“刪除”：

<asp:ButtonColumn CommandName="Delete" Text="Delete"></asp:ButtonColumn>
