Question

我在aspxgridview上有详细问题。当所有详细信息行都展开并且我单击任何详细信息行时； PublicationClickCallback功能仅对最后一个细节网格有效。我会很感激能够帮助我实现目标。我提到了下面的表格和代码

致谢

我的桌子：

CREATE TABLE Table_1(
    T1_Id int IDENTITY(1,1) PRIMARY KEY ,
    T1_Title varchar(20) 
)

GO

CREATE TABLE Table_2(
    T1_Id int ,
    T2_Id int IDENTITY(1,1),
    T2_Title varchar(20) ,
    PRIMARY KEY (T1_Id ASC, T2_Id ASC) ,
    FOREIGN KEY(T1_Id) REFERENCES Table_1 (T1_Id) ON UPDATE CASCADE ON DELETE CASCADE
    )

GO

insert into Table_1 (T1_Title) values ('a'),('b'),('c')

insert into Table_2 (T1_Id,T2_Title) values (1,'a1'),(1,'a2'),(1,'a3')

insert into Table_2 (T1_Id,T2_Title) values (2,'b1'),(2,'b2'),(2,'b3')

insert into Table_2 (T1_Id,T2_Title) values (3,'c1'),(3,'c2'),(3,'c3')

我的html代码：

<script type="text/javascript">
    function PublicationClickCallback(values) {
        var dRow = values;
        var filterExpression = "T2_Title='" + dRow + "'";
        ASPxGridView2.ApplyFilter(filterExpression);
        isFiltered = true;
    }
</script>

                    s.GetRowValues(e.visibleIndex, 'T2_Title', PublicationClickCallback);
                }" />
                <Columns>
                    <dx:GridViewDataTextColumn FieldName="T1_Id" ReadOnly="True" VisibleIndex="0">

        <dx:GridViewDataTextColumn FieldName="T1_Id" ReadOnly="True" VisibleIndex="0">

        <asp:Parameter Name="T2_Id" Type="Int32" />
    </UpdateParameters>
</asp:SqlDataSource>

我的代码：

protected void ASPxGridView2_BeforePerformDataSelect(object sender, EventArgs e)
    {
        Session["T1_Id"] = (sender as ASPxGridView).GetMasterRowKeyValue().ToString();
    }

    protected void ASPxGridView1_DataBound(object sender, EventArgs e)
    {
        ((ASPxGridView)sender).DetailRows.ExpandAllRows();
    }

我如何使aspxgridview detailrow过滤器为真
