我遇到Gridview删除无法正常工作的问题。它似乎与DeleteCommand和DeleteParameters有关。例如,如果我向DeleteCommand提供静态值,而不是使用DeleteParameter,则gridview会删除具有静态指定值的记录。代码如下。
<asp:GridView ID="testGridView" runat="server" AllowSorting="True"
AutoGenerateColumns="False" DataKeyNames="Test_ID"
DataSourceID="dsourceTest">
<Columns>
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
<asp:BoundField DataField="Test_ID" HeaderText="Test_ID"
InsertVisible="False" ReadOnly="True" SortExpression="Test_ID" />
...MORE COLUMNS HERE...
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="dsourceTest" runat="server"
ConflictDetection="CompareAllValues"
ConnectionString="<%$ ConnectionStrings:TestConnectionString %>"
SelectCommand="SELECT Test_ID, C2, C3, C4, C5, C6, COALESCE(C7, '') AS C7, C8 FROM TestTable1"
DeleteCommand="DELETE FROM [TestTable1] WHERE [Test_ID] = @Test_ID">
<DeleteParameters>
<asp:Parameter Name="Test_ID" Type="Int32" />
</DeleteParameters>
</asp:SqlDataSource>
因此,使用上面的DeleteCommand,删除将不起作用。但是,如果我将其更改为DeleteCommand="DELETE FROM [TestTable1] WHERE [Test_ID] = 27"
,并且我在Gridview中点击了一个删除按钮,它将删除Test_ID为27的记录。
答案 0 :(得分:0)
我弄清楚了......我必须将DeleteCommand更改为DeleteCommand="DELETE FROM [ClientService_AP] WHERE [Action_Plan_ID] = @original_Test_ID"
,因为我在SqlDataSource中也有语句OldValuesParameterFormatString="original_{0}"
。
