我使用的是一个简单的gridview,如下所示:
<asp:GridView ID="grdViewData" runat="server" Width="98%" DataKeyNames="RecordID" OnSelectedIndexChanged="grdViewData_SelectedIndexChanged"
onrowcommand="grdViewData_RowCommand">
<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<Columns>
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="lnkEdit" runat="server"
CausesValidation="False" CommandName="Select" OnClientClick="window.scroll(0,0)"
Text="Edit"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="lnkDelete" runat="server"
CausesValidation="False" CommandName="Delete"
OnClientClick="return confirm('Do you want to delete this record?');" Text="Delete" CommandArgument="<%# Container.DataItemIndex %>"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns> </asp:GridView>
为了更新gridview中的记录,我使用gridview_SelectedIndexChanged方法,其中至于删除记录,我使用gridview_RowCommand(如果e.CommandName ==&#34;删除&#34;)方法如下:
protected void grdViewData_SelectedIndexChanged(object sender, EventArgs e)
{
// Code Working properly Controls on page also getting updated
}
protected void grdViewData_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
// Code to Delete Record (Working Properly, Record being deleted.)
// Here Onwards code not working
Message.Text = "Data Deleted Successfully..";
ErrorMessage.Text = "";
}
}
如果更新记录,更新后我有一些代码来更新页面上正常工作的控件,但是如果删除记录,则会删除记录,但页面上的控件不会更新。附加调试器显示代码执行完美,但控件未更新。
我一直在谷歌搜索一天,真的需要知道原因而不是替代。
