Question

当我从网格视图中删除一行时，我收到以下错误。 “指定的参数超出了有效值的范围。参数名称：值”。以下是堆栈跟踪：

请建议我。

没有。我没有手动设置任何索引。我的代码示例如下： “＆GT; '＆gt;

            </Columns>
        </asp:GridView>
        <asp:SqlDataSource ID="srcData" runat="server" ConnectionString="<%$ ConnectionStrings:GermanyCockpitDB %>"
            SelectCommand="SP_BPGetData" SelectCommandType="StoredProcedure"
            OnSelecting="srcBP_Selecting" DeleteCommand="SP_BPDeleteRecord"
            DeleteCommandType="StoredProcedure" OnDeleting="srcData_deleting">
            <SelectParameters>
                <asp:Parameter Name="Manager" Type="String" />
                <asp:Parameter Name="Period1" Type="String" />
                <asp:Parameter Name="Period2" Type="String" />
                <asp:Parameter Name="Period3" Type="String" />
                <asp:Parameter Name="Period4" Type="String" />
            </SelectParameters>
            <DeleteParameters>
                <asp:Parameter Name="ManagerName" Type="String" />
                <asp:Parameter Name="Name" Type="String" />
                <asp:Parameter Name="AName" Type="String" />
            </DeleteParameters>
        </asp:SqlDataSource><br /><br />  protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        gvData.DataSourceID = "srcData";
        gvData.DataBind();
    }

}protected void srcData_deleting(object sender, SqlDataSourceCommandEventArgs e)
{
    e.Command.Parameters["@ManagerName"].Value = "Sample";
}

protected void srcBP_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
    e.Command.Parameters["@ReportsToManager"].Value = "Sample";
    e.Command.Parameters["@Period1"].Value = "0";
    e.Command.Parameters["@Period2"].Value = "1";
    e.Command.Parameters["@Period3"].Value = "2";
    e.Command.Parameters["@Period4"].Value = "3";
}

您似乎正在尝试将selectedindex设置为错误的索引。你是否在删除回调或页面加载（prender，...）中的某个地方手动设置它？

指定的参数超出了有效值的范围。参数名称：值
