[Solved] After upgrade cells return   values

[Janez Kalan]

Hi there,

I hope someone can help me. I have a problem with RadGrid after I install latest Telerik ASP.NET AJAX controls Q1 2013. The code now return   values when I select a row. Before the upgrade everything works perfectly.

The code :

ASPX

<telerik:RadGrid ID="ChangeProjectGrid" runat="server" AllowFilteringByColumn="True"
            AllowSorting="True" Font-Bold="False" Font-Italic="False" Font-Overline="False"
            Font-Size="XX-Small" Font-Strikeout="False" Font-Underline="False" GridLines="None"
            EnableLinqExpressions="False" AutoGenerateColumns="False">
            <ClientSettings AllowColumnsReorder="True" EnablePostBackOnRowClick="True" ReorderColumnsOnClient="True"
                EnableRowHoverStyle="True">
                <Scrolling AllowScroll="True" />
            </ClientSettings>
            <MasterTableView AllowMultiColumnSorting="True">
                <CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>
                <RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">
                    <HeaderStyle Width="20px"></HeaderStyle>
                </RowIndicatorColumn>
                <ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">
                    <HeaderStyle Width="20px"></HeaderStyle>
                </ExpandCollapseColumn>
                <Columns>
                   <telerik:GridBoundColumn DataField="IDProject" FilterControlAltText="Filter IDProject column"
                        UniqueName="IDProject" Visible="False">
                    </telerik:GridBoundColumn>
                       <telerik:GridCheckBoxColumn UniqueName="Active" AllowFiltering="true" AllowSorting="true"
                        DataField="Active" DataType="System.Boolean" HeaderText="Is Active" HeaderStyle-Wrap="false">
                    </telerik:GridCheckBoxColumn>
                    <telerik:GridBoundColumn DataField="ProjectAcronym" FilterControlAltText="Filter ProjectAcronym column"
                        HeaderText="Project Acronym" UniqueName="ProjectAcronym" ReadOnly="True">
                        <HeaderStyle Font-Bold="False" Font-Italic="False" Font-Overline="False" Font-Strikeout="False"
                            Font-Underline="False" Wrap="False" />
                        <ItemStyle Font-Bold="False" Font-Italic="False" Font-Overline="False" Font-Strikeout="False"
                            Font-Underline="False" Wrap="False" />
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn DataField="ProjectTitle" FilterControlAltText="Filter ProjectTitle column"
                        HeaderText="Project Title" UniqueName="ProjectTitle" ReadOnly="True">
                        <HeaderStyle Font-Bold="False" Font-Italic="False" Font-Overline="False" Font-Strikeout="False"
                            Font-Underline="False" Wrap="False" />
                    </telerik:GridBoundColumn>
                          </Columns>
                <EditFormSettings>
                    <EditColumn FilterControlAltText="Filter EditCommandColumn column">
                    </EditColumn>
                </EditFormSettings>
            </MasterTableView>
            <FilterMenu EnableImageSprites="False">
            </FilterMenu>
            <HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">
            </HeaderContextMenu>
        </telerik:RadGrid>

Code behind

Protected Sub ChangeProjectGrid_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles ChangeProjectGrid.ItemCommand

       If TypeOf e.Item Is GridDataItem Then

            Try
                Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)
                Dim ts As EfamtPlus.TrenutnaSeja

                Dim str As String = dataItem("IDProject").Text
               ' code returns empty (& nbsp;) value - on the old telerik controls returns numeric value
            Catch ex As ThreadAbortException
                ' ne naredi nič

            Catch ex As Exception
                PublishException(ex)
                Response.Redirect(NapakaUrl, RedirectParameter)

            Finally
                ClientScript.RegisterStartupScript(Page.GetType(), "closeWindow", "<script type='text/javascript'>RefreshParentPageAndClose()</script>")
            End Try

        End If
    End Sub

I tried to find similar problem on this forum, goole it, but just coudnt find any so if someone could help me i would be very grateful.

Thanks all in the advance.

Hi,

Yes, this is a breaking change introduced in Q1 2013. This modification was done for performance optimization of RadGrid. You could check this sticky thread for more information on the matter and possible work-arounds.
