Hello,

I have a RadGrid for which I have enabled exporting to Excel using the XSLX format. The export works very well except the export removes hyperlinks from the grid and replaces them with plain text. I have a requirement to include in the resulting XSLX file the hyperlink that appears in the grid in a GridHyperlinkColumn. I have tried altering the ExportOnlyData value in the grid's export settings, but that causes the data in the GridHyperlinkColumn to not appear at all. Here is a simplified grid. Thank you for your advice on whether XSLX exports can include hyperlinks.

I am trying to post an array from jQuery on an .aspx page to a method in the codebehind using Telerik AjaxManager. The problem I am having is converting the string to a list or even an array using C#. The string (after using Json.stringify in jQuery) looks like this:

string zoneString = "[[1,[["Ticket Core.AFE"],["Ticket Core.CompanyName"]]],[2,[["Ticket Core.CompanyCity"],["Ticket Core.CompanyState"]]]]"

I tried to deserialize like this:
List<ZoneInfo> zones = JsonConvert.DeserializeObject<List<ZoneInfo>>(zonesString);

But that produced an error.

Here is my client-side code:
var zones = [];

for (var i = 1; i <= zoneCount; i++)

{

var o = $.data(listBox, i.toString());

if(o != undefined){var items = [];var a = o._array;

//pull the key/value

for (x = 0; x < a.length; x++)

{

var item = a[x];

var value = item.get_value();

value items.push([value]);

}

zones.push([i, items]);

}}

jsonZones = JSON.stringify(zones);

var ajaxManager = $find("<%= ((RadAjaxManager)this.Page.Master.FindControl("RadAjaxManager1")).ClientID %>"); ajaxManager.ajaxRequest('CREATEREPORT|' + jsonZones + '|' + tid);

Here is my server-side code:
protected void AjaxMgr_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

string[] args = e.Argument.Split('|');

string sCommand = args[0];

switch (sCommand.ToUpper())

{

case "CREATEREPORT":string zonesString = args[1];

List<ZoneInfo> zones = JsonConvert.DeserializeObject<List<ZoneInfo>>(zonesString);

var template = args[2];

string[] zone = new string[zones.Count];break;

}

InitializeWizard();}

I am implementing a RadGrid with batch mode editing using clientside binding with a RadClientDataSource.   I am finding that calling .hasChanges() results in records flagged for Delete to not actually get deleted when .saveChanges() executes.

This is my setup: 

I created my own button for saving,  as such:

Which calls the following javascript function:

If I make changes to grid data and click the Save button the webservices for the insert, update, delete are being called.

HOWEVER, if I uncomment the "var isDirty...." line in the above .saveChanges() function that calls .hasChanges(),  then the Deletes will no longer save.   The web service for deletes simply does not get called. Inserts and update still work correctly.   If i comment out that line, then the deletes work again.

I found the same behaviour on a LiveDemo example that checks .hasChanges().

https://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/client-data-source-binding/defaultcs.aspx

Steps to reproduce:

- Make any change to the first record, such as modifying the Contact Name.

- On the second record, Click the "x" under the DELETE column to mark it for delete.

- Click any column heading to sort.  (This calls a UserAction event handler that calls .hasChanges())

- Choose to Cancel at the popup prompt.

- Click "Save changes".

- Monitor the browser console, you will find that webservice UpdateCustomers is called,  but DeleteCustomers is not.

Please confirm whether this is a bug and if there is a workaround.

It seems that Column names (title, start time, end time,..) are not translated via dictionary (RadGantt.resx)

Is there a way to change column names?

Hi,

Hello,

I have a styling problem when a dialog is shown in RadEditor (e.g. linkmanager). I have assigned my own skin.:

Skin, EmbeddedSkins and RenderMode are defined in web.config.

I have read some older posts like:

https://www.telerik.com/forums/css-skin-not-setting-for-radeditor-dialogs#D2y6DCqSQkiiOjw0-LqBhA
https://feedback.telerik.com/aspnet-ajax/1377496-adding-dialogscssfile-to-radeditor-changes-radeditor-class

But this doesn't change anything.

editordialog.css

I created the style with the theme builder tool on this site: https://themebuilder.telerik.com/aspnet-ajax

I tested with versions 2019.3.1023 and 2020.1.114

Maybe I missed something important. I hope you can help me.

I have a gallery of three RadMediaPlayer controls.  The sources are added in the code behind.  The mp4 files are sitting in a folder at the root of the app.  The videos play in debug mode, but when I publish and upload to the dev web server, the video players don't play.  They are just black boxes.  I'm using IE11 and Chrome.  In debug mode, the videos all play in both browsers, but after publishing none of them play in either browser.  I have confirmed that the video files are included in the deployed published content and that the folder's path is consistent.  What would cause them to not play after publishing?

This topic is a constant source of confusion for me. Often referenced web pages sometimes seem out of date or conflicting. It's not clear whether the information is accurate for a specific release or for all time. I was going to blog this but maybe it's better if we can create a single forum thread here to become the definitive statement for the web.config definition of Telerik.Web.UI.WebResource.axd.

Here's one excellent reference on the topic:
http://www.telerik.com/help/aspnet-ajax/radscriptmanager.html
Really I think this information applies to most or all controls, but if you're aware of any exceptions for Telerik controls, please post a response here.

For IIS6, consider the following <httpHandler> lines:

and

When Telerik.web.ui is set to Copy Local (not GAC), is it better to not specify the PublicKeyToken?
Is it OK if we do when the DLL isn't in the GAC?  I think so.
Does the PublicKeyToken ever change?  I don't think so.

For IIS7, consider the following <system.webServer><handlers> lines:

and

I don't think the answer to the above questions is different for IIS, but if they are, please let us know.

Given the above, if you're not using the GAC, you should probably never have to change these web.config entries for a given site after they are initially set. See below if you're using the GAC.

Regarding that preCondition runtimeVersion2.0 spec, I'm thinking it doesn't need to be there. The documentation for that attribute says: "Specify the runtimeVersionv2.0 value when the handler should respond only to requests in application pools that are configured to use .NET Framework version 2.0.". I think this is a hold-over from when people were transitioning from v1.1 to 2.0. These days all application pools should be configured for .NET2.  The question becomes: what happens with .NET 3.x or .NET 4? Is it better to add that attribute parameter for the future, or to leave it out for the future?

The help page referenced above provides this sample for IIS7 when Telerik.web.ui.dll is in the GAC:

For anyone not familiar with the syntax, the question might arise:
- Should the name attribute have underscores or periods?
I don't know. See this page for an example where underscores are used:
http://dotnetnotes.i-do-it.com/2009/05/17/CouldNotLoadFileOrAssemblyTelerikWebUI.aspx
I've seen that syntax elsewhere but I'm not sure if it's for web page formatting or if it's valid web.config formatting.

Note that for GAC references the assembly version is required, since the GAC can contain multiple assemblies for the same component but different versions.  The ASSEMBLY_VERSION must be the full version ID for your RadControls release.  For example:
Version=2009.3.1103.35
or
Version=2009.3.1314.35
In this case the PublicKeyToken is required.  More information on the topic is available here:
http://www.telerik.com/help/aspnet-ajax/web-resources-troubleshooting.html

What that means is that if you use the GAC to avoid having multiple copies of DLLs laying around, or to avoid having one application with DLLs for with 2009Q1 and another with 2009Q3, then you need to change web.config to use a specific version of RadControls whenever you upgrade your environment - that is, if you want a specific application to use the new version.

Why did I write this?  I was recently chasing down errors where FireBug is reporting 401 Unauthorized errors for WebResource.axd and Teleric.Web.UI.WebResource.axd. Fiddler2 reports no such errors.  Confused about this I started looking closely at my web.config and settings in my IIS6. I still haven't resolved those issues but I think I have a better understanding of what should be in web.config, so I thought I'd post a discussion on the topic here.  I hope this helps someone.

For anyone doing a search on this topic in the future, please correct any mis-information and provide links to solid resources on the topic. Again, it's important to ensure that someone can tell whether the information they see is only good for the current release, or if it applies to all releases.
