Hello,

I've been searching a lot for the right solution.

I have an old web application, witch uses Telerik RadComboBoxes in a updatepanel. The items in the combo are check boxes and every time I check one item I call a server side methode to update the data. My problem is that I need to keep the dropp dow list opened and I'm not able to acheave that, I tried with cancel the client event of closing, blur, click, but if I do so the server side methode is not called; another solution was to call a javascript method from the server side method, but I get null on the sender ; I've also trided to call a server side methode from the javascript method in the user control but it's not good beacause the method needs to be static and it's not a good solution for me beacause I have to change a lot in this old project.

I have attached a project with 2 comboBox has an exemple with the problem. If anyone has a solution for me I am all ears.

thank you for you time and help !

 

Hi, we are trying to migrate our web application which uses telerik UI web form controls (ex: radlistbox,RadComboBox,Radbutton, telerik ajaxcontrols) from .net framework 4.5.2 to .net 5.

1. Could you please confirm if we can make use of existing telerik dlls in .net core?

2. If not, please let us the alternate way to replace the telerik controls in .net5 with existing license.

We are currently using .net framework with web forms for some of our applications which will probably stay that way in the near future.  But for newer projects, we are going to try and start using .net core technologies. We are a two developer shop and I was wondering if we wanted to leverage telerik tools, would I need both the asp.net ajax AND the .core libraries?  And then two licenses for each for the two developers?  Or is there a bundle for the two technologies so I would only need one license per developer.

Hi, 

Whenever I add any function to the radgrid such as checkbox column then that grid stops working like the filter function in that grid stops working plus the page next and previous function also stop working. What would be the problem? Can anyone help me fix this issue?

Hello all,
i want to add column dynalically to the RadGridView with setting width programatically.
Using below code i am not able set the width of column width inside RadGridView in wpf application.

RadgridView in telerik does not pick the column column specified in the code instead it opens proportionaloity to grid size.

Can you please help regarding how to set the column width programatically.

GridViewDataColumn col = new GridViewDataColumn();

                col.Header = "Order Number";
            col.UniqueName = "TRP";
           
            col.Width = 20 ;

OpenProcsGridView.Columns.Add(col);

the code above does not set the columnwidth and radgrid view open the column width proportionality to grid size .
can we customize the column width acc to user wants

            

GridViewDataColumn col = new GridViewDataColumn();

                col.Header = "Order Number";
            col.UniqueName = "TRP";
           
            col.Width = 20;

OpenProcsGridView.Columns.Add(col);

it does not set the col width to 20 and automatically open the radgridview with default size/header text size\proportiaonally to grid size.

Can you please help that how to set a column width in a customeized way.

            

Hello

I have an account for Telerik UI through my company and I've been going through the Telerik UI for ASP.NET MVC.  I have no issue logging in to my course, but the problem is, a few moments after going through a video, I suddenly get a 403 error and I have to navigate back to keep watching.

Is there something I can do to stop this from happening?

Thanks.
