  • 0

I am trying to hide a TD named ImportnatInfo in a table when the gridview is empty. This gridview has one column from a table in a database to show. When this gridview is empty I want to hide the TD.

The following is the asp code:

<td runat ="server" ID="ImportnatInfo" 
                style="width: inherit; border: 5px double #585858; padding-left: 5px; padding-right: 5px;
                height: inherit; background: #FFFFFF; background-position: center; border-radius: 25px;" 
                enableviewstate="True" visible="False">
                <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BorderStyle="None"
                    DataSourceID="ImportantSqlDataSource">
                    <Columns>
                        <asp:BoundField DataField="Importatnat_Info" SortExpression="Importatnat_Info">
                            <ControlStyle BorderStyle="None" Height="10px" />
                            <FooterStyle BorderStyle="None" Height="10px" />
                            <HeaderStyle BorderStyle="None" Height="10px" />
                            <ItemStyle BorderStyle="None" Height="10px" HorizontalAlign="Center" VerticalAlign="Middle" />
                        </asp:BoundField>
                    </Columns>
                </asp:GridView>
                <asp:SqlDataSource ID="ImportantSqlDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:AgainConnectionString %>"
                    SelectCommand="SELECT [Importatnat_Info] FROM [StationInfoTable] WHERE ([StationNo] = @StationNo)">
                    <SelectParameters>
                        <asp:ControlParameter ControlID="ddlStationNames" Name="StationNo" PropertyName="SelectedValue"
                            Type="Int32" />
                    </SelectParameters>
                </asp:SqlDataSource>
                <br />
            </td>

And the VB.net code is the following:

If GridView1.Rows.Count = 0 Then
        ImportnatInfo.Visible = False
    Else
        ImportnatInfo.Visible = True
    End If

I have dropdownlist and i choose something everytime so if there is nothing in the grid to view, i want the whole TD to be invisible. the TD that im trying to hide when it is empty, the thing the TD is always visible because when there is nothing in the gridView Vb add   so it won’t be empty. so i thought i should use the datasource and still not sure what to do. Any idea how to do that?

            GridView1.DataBind()
    ImportnatInfo.Visible = True
    If GridView1.Rows.Count >= 1 Then
        If GridView1.Rows(0).Cells.Count >= 1 Then
            If GridView1.Rows(0).Cells(0).Text.Trim() = "&nbsp;" Then
                ImportnatInfo.Visible = False
            Else
                ImportnatInfo.Visible = True
            End If
        End If
    Else
        ImportnatInfo.Visible = False
    End If

    Yours is working good but you just need to add Else to show the TD after you check it is not
