我正在尝试更新 gridview，以便一旦从中删除了一行，它就会刷新并且不再自动显示该行。然而，这似乎不起作用。
到目前为止我已经尝试过:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional" >
<ContentTemplate>
<asp:GridView ID="BookingsGridView" runat="server" AutoGenerateColumns="False"
BorderColor="ForestGreen" BorderStyle="Ridge" BorderWidth="10px"
CellPadding="4" ForeColor="#333333" GridLines="None"
onrowdatabound="dgTest_RowDataBound" OnSelectedIndexChanged="Cancel_Booking">
<AlternatingRowStyle BackColor="White" />
<Columns>
<asp:CommandField ShowSelectButton="true" SelectImageUrl="~/Images/Icons/Cross.png" SelectText="Cancel"/>
<asp:BoundField DataField="Book_id" HeaderText="Book_id"/>
<asp:BoundField DataField="Username" HeaderText="Username" />
<asp:BoundField DataField="Client" HeaderText="Client" />
<asp:BoundField DataField="Description" HeaderText="Description" />
<asp:BoundField DataField="BookingDate" HeaderText="BookingDate" />
<asp:BoundField DataField="Duration" HeaderText="Duration" />
<asp:BoundField DataField="Location" HeaderText="Location" />
<asp:BoundField DataField="Payment" HeaderText="Payment" />
</Columns>
<EditRowStyle BackColor="#7C6F57" />
<FooterStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#546E96" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#666666" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#E3EAEB" />
<SelectedRowStyle BackColor="#C5BBAF" Font-Bold="True" ForeColor="#333333"/>
<SortedAscendingCellStyle BackColor="#F8FAFA" />
<SortedAscendingHeaderStyle BackColor="#246B61" />
<SortedDescendingCellStyle BackColor="#D4DFE1" />
<SortedDescendingHeaderStyle BackColor="#15524A" />
<SelectedRowStyle CssClass="SelectedRowStyle" />
</asp:GridView>
<br />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="BookingsGridView" />
</Triggers>
</asp:UpdatePanel>
然后我打电话
UpdatePanel1.Update();
删除行成功
为什么这不起作用？
请您参考如下方法:
如果您有将数据从数据库绑定(bind)到 datagridview 的 Read 方法，只需在您的 delete 方法上再次绑定(bind)它。
像这样:
private void Read()
{
///binding stuff datagridview.datasource = datasource;
}
private void Delete()
{
//Your delete stuff
//call
Read(); // this will refresh your grid after deleting a record.
}
最好的问候
