I am using a RadGrid and when the grid populates I would like to use alternate row colour depending on the values of the Works Order number if the previous value is the same as the current row value. For example, I have the following rows below. I would like the row colour with WO 11222 to be "rgRow" and the WO with 45874 to be row colour "rgAltRow" then back to rgRow  for the next WO. So I basically want the alternate row colour to work on change of WO number.

Is there a way to achieve this please?

WO      Qty   Part

11222     3     XYZ

11222     4     XYZ

45874    1     UYH

45874   3     UYH

Hi,

I was very pleased to see the addition of the RadSignature-control to the Telerik UI for ASP-NET AJAX suite, however there are some functionalities, which we would require to properly make use of this control.

1. If one wants to read the resulting signature server-side (after a button-click / form submission), one kind of has to work with a lot of javascript and hidden input fields to transfer the base64-encoded png towards the server. It would be way nicer, if you could provide the content of the signature as a server-side property of the RadSignature-control (during post-back).
2. Relating to 1.: I've managed to use the client-event OnChange to write a hidden field each time the signature changes, but there's no event to hook in case of a reset; therefore I cannot detect resets to reset the value of the hidden field. (And let's just say, it's infeasible to us to read the signature-content on form submission because of dynamically generated controls.) Thus I cannot use the built-in reset button, but I would have to implement it myself to be able to reset the hidden field and the signature-control at the same time (using the js-method "reset" of the kendo widget).
   
3. If one opens a dialog/window containing a RadSignature-control and resizes the dialog (e.g. make it twice as large) then the position of the cursor on the canvas does not match the position of the strokes anymore. Painting in the top-left corner is sort of okay/close, but the further one moves the cursor towards the bottom-right, the bigger the offset will be.
4. It would be great, if the control would provide functionality to validate for mandatory user input. I.e. I (as a developer) don't want to have to memorize/manage a variable focusedSignatureDefaultContent (c.f. docs for RadSignature) for each RadSignature-control I want to put on a page. Best case, the RadSignature control manages this data for me and I can either read a boolean to determine if its contents have changed (client- and especially server-side).

And some other bugs, I've stumbled upon (- which are not as relevant to us):

• If you paint a stroke on the canvas, then "maximize" the RadSignature-control (effectively zooming in on the control) and then paint a second stroke, you'll see that those strokes will have a different line width; the second one being bigger.
• If you repeatedly maximize/minimize the RadSignature control and draw a stroke each time on the bottom of the canvas, then the resulting image will get distorted.

If you need any further information on any of those topics, feel free to ask.

Kind regards,
Matthias

RadNotification seemingly does not have focus trap

Am i missing something?

How to show the filter check list item for a datetime column as like excel. Like the Attached image below.

I saw this post: Hide XAxis Labels in UI for ASP.NET AJAX | Telerik Forums

And I would like to use the OnBeforeLayout server event for my project. But I couldn't find it in documentation. Where is this event now? Did telerik team rename it or just remove it?

Could someone tell me?

Thanks.

Why am I getting "RadGrid1 is not declared" ?

I want to use the Radeditor to edit HTML data.  However, I have a special image editor that I want to execute when the user double clicks on certain images in the document.  Is this possible with Radeditor?  Can I execute Javascript in the editor?

Dear Telerik Team,

We have purchased Telerik UI for ASP.NET AJAX UI 2010.1519. Now we are facing vulnerable issues as it is using jQuery 1.4.2.

One of the Telerik doc tells that

When Telerik upgraded jQuery version to 3.3.1, it faces incompatibilities with the MS AJAX framework and its __doPostBack() method. Due to which, Telerik downgraded jQuery version Telerik UI for ASP.NET AJAX R1 2019 - present are using a modified jQuery version 1.12.4 that includes security vulnerability backport fixes.

Is there a fix to overcome this issue other than upgrading the Telerik version to 2019 or greater?

I would like to add a hyper link to the node of an Org Chart, and I tried to add like:

But it won't work. The hyperlink is not even clickable. Can anyone tell me how to add hyperlink to OrgChart?

As described in the titel, could someone give me some suggestions? Much appreciated.
