Hi i have a tab strip & a number of page views associated with it.

what i've also got is some .net buttons which allow the user to also navigate through the tabs if they wish, like a next and previous.

I'd like to disable the previous button when the user is on the first tab and disable the next button when they're on the last tab.

hopefully that makes sense, i want to do this without having to do a postback which i'm sure is possible.

I suppose it would be some code that goes into the buttons Enabled attribute, something like Enabled=' if currenttab = firsttab then false else true' in the example of the 'previous' button.

Many thanks

Alan

webform radwindow refused to connect

The minimum code. Why radwindow can show, let's say "bing.com", "www.wikipedia.org", but refused to show "google.com" and even "telerik.com". Even telerik demo gives "www.google.com refused to connect", or "www.telerik.com refused to connect"

Scheduler - Bypass popup when right clicking to add a new Appointment

When right clicking on a scheduler's day, for instance, I can click on "New Appointment", and the popup box with "Options", "Cancel", etc. shows up to specify the Subject and/or options. Is there a way I can just click "New Appointment" and bypass that popup, and just create the new appointment? The box below is what I want to completely bypass. Any help is appreciated.

Gantt Resource Percentage Bug

Edit: Looks like I posted this in wrong place. Now posted in feedback and bugs.

When assigning multiple resources and percentages, the first item in list always goes back to 100%.

It saves back to UI correctly but as soon as you leave or refresh page it goes back to 100% on first item and that's what's saved in database.

The online demo has the same code but demo doesn't save at all.

See attached screen shots.

radGrid with image...click show full image

I have a bound grid that contains an image. Since the image is about the size of a thumbnail...I want to give the user the ability to click the image and have it displayed in full. I figured a good way to do this would be to use a RadLightBox. Am I barking down the right path? Is there a better way?

RadGrid Batch Update with checkbox template column

I followed the documentation example for using a check box column(see link below). The issue I'm having is when the BatchEditCommand event fires after the clicking the "Save Changes" item command button, the BatchEditCommand object is always empty so I cannot get the Hash table values to update the record without without using the Open-Edit click event.

Also, can someone provide a sample of using this method with a RadSwitch instead of a checkbox?

Thanks in advance for any help.

Do not export ColumnGroups to Excel

Hello,

I would like not to export a ColumnGroups to Excel, if I simply make the columns that are part of the column group invisible it presents an error.

I really wish I didn't have ColumnGroups, as it doesn't make sense in my spreadsheet.

Thank you very much in advance

Filter data with double quotes

Hi!

I have issue with filter radGrid, when data in filter field contains double quotes ("). For example: <"Telerik" company>. In this case there is no filter action, and filter field cleaning after pressing on filter button.
This issue exist in online filter demo: http://demos.telerik.com/aspnet-ajax/Grid/Examples/GeneralFeatures/Filtering/DefaultCS.aspx
Try type in filter field some text with double quote and apply filter action. No filter will be apply and filter field will be clear.
There is workaround or fix for this issue?
Thank you.

P.S. Sorry for my English.

Injection vulnerability in RadButton

Our company is using HCL AppScan to expose possible security vulnerabilities. Recently, the scans have started returning issues of high severity related to Blind LDAP Injection because the parameters of the hidden ClientState for RadButtons, such as buttonAbort_ClientState, can be appended to affect the response.

The test uses the following logic:
Four requests are sent.
The last is logically equal to the originalThe next-to-last is different. Any others are for control purposes.A comparison of the last two responses with the first (the last is similar to it, and the next-to-last is different) indicates that the application is vulnerable.

These are not LDAP issues since LDAP is not implemented on the server but our security team in concerned this is a vulnerability because the parameter can be appended without sanitization.

Is there legitimate reason for concern? If so do you have any suggestions for remediation. We are using version 2023.1.323.45.

Regards, Joel
