Hello,

I am facing an issue when uploading to AWS S3, which is automatic renaming of the uploaded file

original file name is BD-september-2022-quarter.csv

and the new file name is : 03fb8435-90ea-4378-a602-925d37db8277_BD-september-2022-quarter.csv

i don't know why after upload the original filename is not being kept

 <telerik:RadCloudUpload ID="RadCloudUpload1" runat="server" RenderMode="Lightweight" MultipleFileSelection="Automatic" OnClientFileUploading="OnClientFileUploading" AllowedFileExtensions=".csv" ProviderType="Amazon" localization-SelectButtonText="Browse to Upload ..."  MaxFileSize="3145728"  OnFileUploaded="RadCloudUpload1_FileUploaded"/>

Thanks for your help

Save radgrid inside RadDataForm before generating a report (PDF)

Hello

I have a ASP.NET AJAX site which lets you generate bills. These have a header and lines.

It does have a button to generate a PDF report of this bill.

The form is a RadDataForm, always in edit mode, and inside of it, besides header fields, it's a RadGrid for the bill lines .

Until now, you have to first click the built in save button in the RadDataForm, then you can click on the generate PDF, otherwise the PDF is outdated (it doesn't save the modified header and lines). Now it's required that only clicking on the generate PDF button first save everything in the radDataForm, then it generates the PDF with updated values. I managed to save the header data before executing the PDF code but I can't figure out how to save the lines (RadGrid), because if I trigger it, then stops executing and the PDF report isn't generated at all.

The Save button has a client side Javascript event attached to save the RadGrid status.

 var grid1 = $telerik.findControl(document.documentElement, "RadGrid1");
var batchManager1 = grid1.get_batchEditingManager();
var hasChanges = batchManager1.hasChanges(grid1.get_masterTableView());
if (hasChanges) {
  batchManager1.saveTableChanges([grid1.get_masterTableView()]);
  ajaxPanel.ajaxRequest("saveChanges");

} else {
  var ajaxPanel = $telerik.findControl(document.documentElement, "RadAjaxPanel1");
  ajaxPanel.ajaxRequest("saveChanges");
}

If I add that same client side function in the generate PDF, it saves the RadGrid but it doesn't execute the generate PDF code (possibly due to the Postback preventing it to reach the server side function that generates the report and PDF)

I use the BatchEditCommand to manually get the updated, inserted or deleted rows and execute the SQL queries to do that. But I can't get the list of commands (the GridBatchEditingEventArgs e) without this event

Is there a way to save the radDataForm first (including the RadGrid) then generating the PDF file (it's a server side function)

Many thanks!

raddateinput event server-side

I have to change the value of a raddateinput server side.

On client side I have an Ajax function than show the age.

What I have to use on server-side and on client-side to fie event?

For example this doesn't works:

server side:

RdMyDateInput.SelectedDate = DateTime.Parse(MyStringDate);

client side:

<telerik:RadDateInput ID="RdNyDateInput" runat="server" ClientEvents-OnValueChanged="AgeCount" Culture="it-IT" MaxDate="2999-12-31" MinDate="1900-01-01" Skin="Silk">
                 <ClientEvents OnValueChanged ="AgeCount"></ClientEvents>
</telerik:RadDateInput>

the event fires only on web page, not by server side.

Thanks

RadEditor Hyperlink document manager Insert button event

Hi Telerik,

I want to trigger the Document manager insert button event when I inserting an attachments into the hyperlink manager when I open the document manager from the hyperlink manager.

I tried by adding the below code based on the documentation,

Added OnClientPasteHtml event for RadEditor

<telerik:RadEditor ID="reNotes" runat="server" Width="800" Height="300" Skin="Windows7" 
                                OnClientLoad="OnClientLoad" EnableResize="False" AutoResizeHeight="true" EditModes="Design"
                                OnClientCommandExecuting="OnClientCommandExecuting" OnClientPasteHtml="OnClientPasteHtml" >
                                <DocumentManager MaxUploadFileSize="20000000" SearchPatterns="*.*" />
                                <Content>                                     
                                
                                </Content>
                            </telerik:RadEditor>

Also added the corresponding function in the script

 function OnClientPasteHtml(sender, args) {
                    alert(10);
                    debugger;
                    var commandName = args.get_commandName();
                    var value = args.get_value();

                    if (commandName == "Paste") {
                        // The StripPathsFilter() method receives as a parameter an array of strings (devided by a white space) that will be stripped from the absolute links.
                        var domainName = "http://" + window.location.host; //returns the hostname and port number of the current URL
                        var filter = new Telerik.Web.UI.Editor.StripPathsFilter([domainName]); //strip the domain name from the absolute path

                        var contentElement = document.createElement("SPAN");
                        //contentElement.innerHTML = value;
                        var newElement = filter.getHtmlContent(contentElement);
                        alert(newElement.outerHTML);
                        //args.set_value(newElement.outerHTML);  //set the modified pasted content in the editor
                    }
                }

But the event not triggering when the insert button clicked.

Please note : I opened the document manager from the hyperlink manager popup.

Please see the screenshot

Is there any way to trigger the insert button event, So that I can access the current attachment url and replace the same with an encrypted url and also display the encrypted URL in the url field of the hyperlink manager.

Thanks & regards,

Editor

How can I restrict the types of files a user can select when using the GridAttachmentColumn in a RADGrid control?

Within a page, I have the following -

<telerik:RadGrid ...

<telerik:GridAttachmentColumn ... AllowedFileExtensions=".png,.gif,.jpg,.jpeg" ... />

</ telerik:RadGrid>

When editing an item within the grid, and clicking the 'Select' option on the grid's edit column related to the GridAttachmentColumn, I'm receiving this popup -

I want to restrict the files a user can select to upload through this dialog to those defined within the 'AllowedFileExtensions' property of the control, either from within the HTML, or in the code behind.

How can I go about doing that? If this is not the correct place to be asking this question, where on the forum should I be asking this question?

Thanks.

RadSpreadsheet Cannot paste, because the copy area and the paste area are not the same size and shape

I'd like to dynamically increase the grid size (add rows and or columns) when a user attempts to paste data that exceeds the default size.

Is there an event that I can capture that fires before the 'Cannot paste, because the copy area and the paste area are not the same size and shape' error occurs?

I've tried OnClientChanging and OnClientPaste but the error is thrown before either of these events fire.

[Solved] Maintaining RadGrid current page/row index after navigating away from Radgrid page.

I have a Radgrid on ASP.NET Form (RadControls for ASP.NET AJAX Q2 2012 SP2 with VS 2010) , which is bound to a Linq data source and set it to have 10 records per page , sorting, filtering is enabled. Also have a hyper a link column (Radgrid Mastertable Databound column) on the Radgrid, such that a user can click it & navigate to another external page (details.aspx) from the list. I am passing Master Table Primary Key that is Parent key of all rows in Detail Page. On the details page, they have "Back" button to return to the RadGrid page.

I am looking for sample code snippet on the Server/Client Side on how to specify the page/row index to set the RadGrid after data binding. The idea is to ensure the user navigates to the same Radgrid (Parent) page/row index they were originally on after exiting from details.aspx.

Thanks

It seems problem just occurs, when there are more then 3024 Markers on the map. Below this count there is now problem.

I allready changed the MaxJsonLength in the web.config. That changed nothing.
