[Solved] BatchEditCommand OldValues not set for GridTemplateColumn

Good afternoon,

I'm using a RadGrid with Batch Editing. The grid is populated using OnNeedDataSource.

<telerik:RadGrid ID="RadGridEntries" runat="server" RenderMode="Lightweight" AllowSorting="True" CellSpacing="-1" GridLines="Horizontal"
    OnNeedDataSource="RadGridEntries_NeedDataSource" AllowAutomaticUpdates="false"
    AllowAutomaticInserts="false" AllowAutomaticDeletes="false" OnBatchEditCommand="RadGridEntries_BatchEditCommand"
    OnPreRender="RadGridEntries_PreRender">
    <ClientSettings>
        <Scrolling AllowScroll="true" UseStaticHeaders="true" SaveScrollPosition="true" />
    </ClientSettings>
    <MasterTableView Name="Authorities" AutoGenerateColumns="false" DataKeyNames="Index_id"
        CommandItemDisplay="Top" EditMode="Batch" BatchEditingSettings-OpenEditingEvent="DblClick" HeaderStyle-HorizontalAlign="Center">
        <CommandItemSettings ShowRefreshButton="false" />
        <BatchEditingSettings EditType="Row" HighlightDeletedRows="true" />
        <Columns>
            <telerik:GridBoundColumn DataField="Index_id" UniqueName="Index_id" ReadOnly="true" Visible="false" Exportable="false" />
            <telerik:GridBoundColumn DataField="Authority" SortExpression="Authority" UniqueName="Authority"
                HeaderText="Authority" MaxLength="2">
				<ColumnValidationSettings EnableRequiredFieldValidation="true">
					<RequiredFieldValidator ForeColor="Red" Text="*Authority is required" Display="Dynamic">
					</RequiredFieldValidator>
				</ColumnValidationSettings>
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="Short_description" SortExpression="Short_description" UniqueName="Short_description"
                MaxLength="30" HeaderText="Short Description" ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="150px">
				<ColumnValidationSettings EnableRequiredFieldValidation="true">
					<RequiredFieldValidator ForeColor="Red" Text="*Short Description is required" Display="Dynamic">
					</RequiredFieldValidator>
				</ColumnValidationSettings>
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="Long_description" SortExpression="Long_description" UniqueName="Long_description"
                MaxLength="100" HeaderText="Long Description" ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="200px" />
            <telerik:GridTemplateColumn DataField="Percentage" SortExpression="Percentage" UniqueName="Percentage" HeaderText="Percentage">
                <ItemTemplate>
                    <%#DataBinder.Eval(Container.DataItem, "Percentage","{0} %")%>
                </ItemTemplate>
                <EditItemTemplate>
                    <span>
                        <telerik:RadNumericTextBox RenderMode="Lightweight" Width="75px" runat="server" ID="txtPercentage"
                            MaxValue="100" MinValue="-100">
                            <NumberFormat DecimalDigits="3" NegativePattern="-n %" PositivePattern="n %" />
                        </telerik:RadNumericTextBox>
                        <span style="color: Red">
                            <asp:RequiredFieldValidator ID="rvPercentage"
                                ControlToValidate="txtPercentage" ErrorMessage="*Percentage is required" runat="server" Display="Dynamic">
                            </asp:RequiredFieldValidator>
                        </span>
                    </span>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridCheckBoxColumn DataField="IsPriceList" DataType="System.Boolean" SortExpression="IsPriceList"
                StringFalseValue="0" StringTrueValue="1" HeaderText="Price List" />
            <telerik:GridBoundColumn DataField="Date_amended" SortExpression="Date_amended" HeaderText="Date Amended" ReadOnly="true" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

In RadGridEntries_BatchEditCommand I'm capturing the old and new values:

Hashtable newValues = command.NewValues;
Hashtable oldValues = command.OldValues;

But the Percentage template column is missing from OldValues:

The Percentage column is stored as a decimal(6,3). I'm trying to display the value with the 3 d.p and a % sign. It's not stored as a percentage i.e. if the value is stored as 10.505 then it is displayed as 10.505 - I'm not storing it divided by 100.

I'm using the Command Item buttons to Save and Insert.

What can I do to make sure that the Percentage Old Value is stored so that I can compare it to the New Value?

Kind regards,

Richard

Error exporting Excel sheet - Telerik.Windows.Documents.Spreadsheet

I just updated to ASP>NET AJAX 2024 Q4 and I get an error in the following code...

string fileName = "SampleFile.xlsx"; 
 
IWorkbookFormatProvider formatProvider = new XlsxFormatProvider(); 
 
using (Stream output = new FileStream(fileName, FileMode.Create)) 
{ 
    formatProvider.Export(workbook, output); 
}

'formatProvider.Export(workbook, output);' is looking for an additional parameter now 'TimeSpan? timeout'.

I took a guess and entered null and it seems to work.

What are the options for this new parameter?

RadEditor forgets position when switching between Design tab and HTML tab

When you switch between the Design tab and the HTML tab in the RadEditor, it does not remember your position in the text/content.

It seems like this is a bug, but I am wondering if there is any way to tell the RadEditor to remember the position when switching between those two tabs.

If you have a large amount of content with many HTML tags it becomes quite difficult to find the exact position you were in on the other tab.

                        </div>
                        </AdvancedEditTemplate>

I want the close button to revert to the weekview from the edit form. I can get the form to close but it's then blank. How do I show the radscheduler weekview view again on close. here is my closeEditForm javascript function

        function closeEditForm() {
            var scheduler = $find("<%= RadScheduler1.ClientID %>");
            scheduler.hideAdvancedForm();
            // Switch the view to Month View
            scheduler.set_selectedView(Telerik.Web.UI.SchedulerViewType.MonthView);
            scheduler.navigateToDate(new Date()); // Optional: Navigate to today's date 
            return false;
        }

thanks!!

reorder column

Hello,

I have two projects with very similar code and I can identify the properties that concern the reordering of columns on the client:

<ClientSettings AllowColumnsReorder="True" ReorderColumnsOnClient="True" EnableRowHoverStyle="true">

The difference between the projects is that one uses a masterpage.

Any suggestions?

The style sheet '~/Scripts/app.js' is not located in any of the 'Style Sheet' folders designated in the web.config.

We recently migrated our website over from a 2012 server to a 2022 server. Upon migration we're now receiving the following error:

Telerik.Web.UI.InsecureExternalStyleSheetException: The style sheet '~/Scripts/app.js' is not located in any of the 'Style Sheet' folders designated in the web.config.
Telerik.Web.UI.InsecureExternalStyleSheetException: Telerik.Web.UI.InsecureExternalStyleSheetException: The style sheet '~/Scripts/app.js' is not located in any of the 'Style Sheet' folders designated in the web.config.
  at Telerik.Web.UI.ExternalScriptHelper.ResolveSecurePath(String scriptRelativePath)

We then found this link: Telerik Forums Post

Following the instructions, we now have the following in our web.config file in <appSettings>:

<add key="Telerik.Web.UI.StyleSheetFolders" value="~/Scripts/; ~/styles/; ~/ReportViewer/js/; ~/kendo/js/;" />

We added multiple value's for the multiple different files that were being placed in the error messages.

We also ensured that our Master files for our different types of pages have been updated to match:

        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <Scripts>
                <telerik:RadScriptReference Path="~/Scripts/app.js" />
            </Scripts>
        </telerik:RadScriptManager>
        <telerik:RadStyleSheetManager runat="server" ID="RadStyleSheetManager1">
            <StyleSheets>
                <telerik:StyleSheetReference Path="~/Scripts/app.js" />
            </StyleSheets>
        </telerik:RadStyleSheetManager>

The errors are still being thrown. The pages work fine, but we don't want to be continuously being given these errors over and over again in Stackify.
