 <asp:SqlDataSource ID="SqlDataSource1" runat="server"

        SelectCommand="SELECT ID,owner,PostedBy,Path,PostDate,status,
                    CASE status
                    WHEN '0'  THEN 'New'
                    WHEN '1'  THEN 'Listened'
                    WHEN '99' THEN 'Removed'
                    else ' unknown'
                    END as StatusName
                    FROM Tbl_wallpost
                    WHERE CONVERT (varchar(10), PostDate, 103) &gt;= @dateFrom AND CONVERT (varchar(10), PostDate, 103) &lt;= @dateTo" 
        UpdateCommand="UPDATE Tbl_wallpost SET status=@status WHERE ID=@ID"

        FilterExpression="owner='{0}'" EnableCaching="true">
                <FilterParameters>
                    <asp:ControlParameter Name="owner" ControlId="ownerNo" PropertyName="Text"/>

                </FilterParameters>
        <SelectParameters>
            <asp:ControlParameter ControlID="TextBox1" Name="dateFrom" PropertyName="Text" />
            <asp:ControlParameter ControlID="TextBox2" Name="dateTo" PropertyName="Text" />
        </SelectParameters>

我的问题是当我想写FilterExpression =“owner ='{0}'或者PostedBy ='{1}'”时，过滤器显示错误的结果？什么原因？我需要按所有者过滤数据并单独发布.PLz建议。

Answer 1

FilterExpression="owner='{0}' OR PostedBy='{1}'"

只要您有两个FilterParameters

，

就应该有效

<FilterParameters>
    <asp:ControlParameter Name="owner" ControlId="ownerNo" 
                   PropertyName="Text" ConvertEmptyStringToNull="true"/>
    <asp:ControlParameter Name="PostedBy" ControlId="PostedBy" 
                   PropertyName="Text" ConvertEmptyStringToNull="true"/>
</FilterParameters>
