Question

虽然我在删除事件中删除了一行，但我希望从GridView获得brandid。

我该怎么做？

<asp:GridView ID="GridView1" OnRowDeleted="GridView1_RowDeleted" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="Id" DataSourceID="SqlDataSource1">
    <Columns>
        <asp:CommandField ShowEditButton="True" ShowSelectButton="True" ShowDeleteButton="True" />
        <asp:BoundField DataField="brandname" HeaderText="brandname" SortExpression="brandname" />
        <asp:BoundField DataField="info" HeaderText="info" SortExpression="info" />
        <asp:ButtonField DataTextField="brandname" HeaderText="brandname" ButtonType="Button"/>
        <asp:BoundField DataField="Id" HeaderText="brandid" ReadOnly="True" SortExpression="Id" />
    </Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConflictDetection="CompareAllValues" ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" DeleteCommand="DELETE FROM [brand_tbl] WHERE [Id] = @original_Id AND (([brandname] = @original_brandname) OR ([brandname] IS NULL AND @original_brandname IS NULL)) AND (([info] = @original_info) OR ([info] IS NULL AND @original_info IS NULL))" InsertCommand="INSERT INTO [brand_tbl] ([brandname], [info]) VALUES (@brandname, @info)" OldValuesParameterFormatString="original_{0}" SelectCommand="SELECT * FROM [brand_tbl]" UpdateCommand="UPDATE [brand_tbl] SET [brandname] = @brandname, [info] = @info WHERE [Id] = @original_Id AND (([brandname] = @original_brandname) OR ([brandname] IS NULL AND @original_brandname IS NULL)) AND (([info] = @original_info) OR ([info] IS NULL AND @original_info IS NULL))">
    <DeleteParameters>
        <asp:Parameter Name="original_Id" Type="Int32" />
        <asp:Parameter Name="original_brandname" Type="String" />
        <asp:Parameter Name="original_info" Type="String" />
    </DeleteParameters>
    <InsertParameters>
        <asp:Parameter Name="brandname" Type="String" />
        <asp:Parameter Name="info" Type="String" />
    </InsertParameters>
    <UpdateParameters>
        <asp:Parameter Name="brandname" Type="String" />
        <asp:Parameter Name="info" Type="String" />
        <asp:Parameter Name="original_Id" Type="Int32" />
        <asp:Parameter Name="original_brandname" Type="String" />
        <asp:Parameter Name="original_info" Type="String" />
    </UpdateParameters>
</asp:SqlDataSource>

Answer 1

在您的RowDeleted事件中，您只需抓取e.Keys["Id"].ToString()即可获得品牌ID的值。这是有效的，因为你已经定义了＆＃34; Id＆＃34;作为GridView的datakeynames值。

protected void GridView1_RowDeleted (Object sender, GridViewDeletedEventArgs e)
{
    string brandId = e.Keys["Id"].ToString();
}

请将此检查到您的代码中

<强>即rowindex显示为已删除事件中行的ID

如何在gridview中获取已删除的行ID？
