Question

我有一个gridview，

单击Button ADD时，文本框值将添加到gridview。
在gridview中添加值后，我想选择一行并单击“删除”按钮，但在删除时发生错误。

我的GridView代码

<asp:GridView ClientIDMode="Static" ID="GridPesonal" runat="server" AutoGenerateColumns="False" Class="GrdSty" Width="100%" DataKeyNames="RowNumber">
    <Columns>
        <asp:BoundField DataField="RowNumber" HeaderText="ردیف">
        </asp:BoundField>
        <asp:BoundField DataField="StartDate" HeaderText="از تاریخ"> 
        </asp:BoundField>
        <asp:BoundField DataField="EndDate" HeaderText="تا تاریخ">
        </asp:BoundField>
        <asp:BoundField DataField="SherkatName" HeaderText="نام شرکت،سازمان یا موسسه" >
        </asp:BoundField>
        <asp:BoundField DataField="WorkUnitName" HeaderText="واحد محل کار"> 
        </asp:BoundField>
        <asp:BoundField DataField="Sharh" HeaderText="شرح دقیق شغل/سمت/مسئولیت" >
        </asp:BoundField>
        <asp:BoundField DataField="WorkTime" HeaderText="زمان کار" >
        </asp:BoundField>
        <asp:BoundField DataField="Description" HeaderText="توضیحات">
        </asp:BoundField>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:CheckBox ID="SavabegSelect" runat="server" AutoPostBack="True" OnCheckedChanged="SavabegSelect_CheckedChanged" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
    <EmptyDataTemplate>
        موردی ثبت نشده است.
    </EmptyDataTemplate>
</asp:GridView>

Btn删除代码

<asp:Button ClientIDMode="Static" ID="BtnDelete" CssClass="btnregister"  runat="server" Text="حذف" OnClick="BtnDelete_Click"  />

btn删除后面的代码

protected void BtnDelete_Click(object sender, EventArgs e)
{
     foreach (GridViewRow gvrow in GridPesonal.Rows)
     {
         CheckBox chkdelete = (CheckBox)gvrow.FindControl("SavabegSelect");
          if (chkdelete.Checked)
          {
              GridPesonal.DeleteRow(gvrow.RowIndex);
          }

   } 
 }

执行上述代码时，此错误显示为

The GridView 'GridPesonal' fired event RowDeleting which wasn't handled.

Answer 1

您是否在Delete上使用了命令名BtnDelete 从Delete Button删除它将起作用。

Answer 2

如果你喜欢这个

<asp:GridView ID="gvRoute" DataKeyNames="Route" runat="server" AutoGenerateColumns="false"
                           AllowPaging="true" Width="30%" 
                          onrowdeleting="gvRoute_RowDeleting">

删除onrowdeleting="gvRoute_RowDeleting

或

的事件

protected void gvRoute_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {
          \\
         }

或使用"CommandName"属性"Delete"

或使用OnClick

<asp:GridView ClientIDMode="Static" ID="GridPesonal" runat="server" AutoGenerateColumns="False" Class="GrdSty" Width="100%" DataKeyNames="RowNumber" OnClick="BtnDelete">

在没有保存在DB中的RowDeleting的按钮单击中删除GridView Rows
