what is i have to do

Thanks in advance

Hi

I want to display report using radtreeview controls. Can somebody help me regarding that i am new to radtreeview control. Currently I am using radgridview to display report.

Thanks 

I have a PropertyGrid with 2 types of editors ; SpinEditor and DropDownListEditor. After the user changes a value in a SpinEditor, it triggers the event PropertyValueChange. However, after the user selects a new value in the DropDownListEditor, it does not trigger the PropertyValueChange. The ValueChanged event is fired but the new data is not saved in the item at this point. 

How can I make it trigger the PropertyValueChange event after the user changes the value in the DropDownList?

Thanks!

Very simple problem. 

How to get a CLB with only one item ever checked? There's a simple property to allow only single-select, but not one for 'only allow one box to be checked at a time'

How to do this, from inside the 'ItemCheckedChanged' event handler, without causing a stack overflow, as the previously cheked items are un-checked?

I feel this must be really easy - am I just missing something?

Hi,

I'm looking for a way to forbid resizing a task but allow users to move them to another time.

If found issues about blocking events (https://www.telerik.com/forums/how-to-disable-edit-add-new-delete-items), but it implies to "cancelstart" on the dragDropService.

I can't find an event that gives me enough information to choose between "allow" and "cancel" modification if its "move" or "resize"

ps: I had to remove packages of the solution so it respects the 20MB limit, hope that won't cause any trouble.

Thanks for your time and help.

Simon.

hi 

what bottom border text box control not show after enable Embedded Label

I would be great if the RadProgresBar control was a bit more tolerant of values whih are > max value.

OK, so this is a programming errot, but the error message the user sees is a bit extreme - a .NET error.

Perhaps the Telelrik framework might just ignore these values which are > max value , and just set to 'max value'.

I've made the change to the App.config file to set to use the 'Fluent' Theme for all forms everywhere in the application:

 <add key="TelerikWinFormsThemeName" value="Fluent" />

..which looks perfect in the Designer, but the runtime is still using some other theme.

 Designer

 Runtime

The form does not specify a Theme, so I thought it would use the 'Fluent' theme which I specified.

Do I need to do something else to make the runtime form use the right theme? I'm confused....

I'm experimenting thia for almost one week. I almost read every post in forum and also other sources. problem is simle. I want to flash a grid cell when value changes. It works them column and row count is small but when grid is in fullscreen form with 20 columns and lets say 100 rows, cells sometimes blink, sometimes not. I noticed that when you decrease blink time it doenst work. when you go up to 150 ms and up it works. this tells me it has something todo with refresh rate or something. same problem exists with other solution approaches in forum.

Can I kindly ask you yo provide a working a flashing cell sample. I really tried to use every event, every suggestion in this forum.... and also its not first time I face the problem. Last year I had again and at the end I gave up and didnt use flashing function in my project. But this time I reaaly need this.

And also I should mention that this is a very common practice nowadays, so radgrid should able to handle that.

best.

' at the form load event..
