Team,
    We are upgrading Telerik version from 2013 to latest version. 
    We are facing issues, while loading the value in drop down list in our application. We need your help to sort out that problem. 
But in the older version, its working fine.

This is impacting our upgrading project and move forward.
Please arrange the Team meeting to explain the issue and get the solution as priority.


Regards,
Nagaraju

I started receiving the following error message yesterday when trying to create a new RadForm using UI for WinForms in VS2022.  Any idea as to how to resolve this?

 

Error occurred while running wizard.

Hi ,

We are using RadRibbonBar in our application and have a requirement to add a custom banner(RadLabel) in between the RadRibbonBar title and the Tab strip as per the attached mockup screen shot. 

 

 

Tried some approaches to achieve this , but it was not successful. Can you please let us know how we can achieve this requirement?.

 

Thanks.

Hi,

is there a way to show a checkbox cell also when the user add a new row in a Virtual Grid?

The screenshot are taken from your code example, I only changed AllowAddNewRow to true.

 

Also, is there a way to set default values like the DefaultValueNeeded event of RadGridView?

 

Thank you!

I have data from a table (child) that may or may not contain values from another table (parent).  When I use the data in the pivot grid, I only see the party field values that exist in my child table, I want to be able to see all the values from the parent table

Example

                  Status      ACTIVE          INACTIVE         DISABLED       CANCELED

Positions

FIRST BASE                    1                           0                           0                    0
SECOND BASE               2                           1                            0                    0
SHORT STOP                 0                           0                           0                    0
THIRD BASE                  10                          10                         13                    12

 

Is this at all possible, by just feeding the data to the DataSource of the pivot grid?

 

Thanks

Is there the ability to set the default STEP for a field that has not been used as an aggregate but is in the list for the user to select? We have an AGE field, and when the user drags it to either the ROW or COLUMN, the default STEP is 100. We need it to default to 10. Can we do this programmatically?

 

TIA.

Hi.

I am playing around with a trial version of the WinForms suite. There are a couple of issues I am seeing from the start and haven't been able to find a solution, so I was hoping posting here might lead me in the correct direction.

 

First: Telerik UI for Winforms > Convert to Telerik Controls crashes Visual Studio 2022 (.NET 8)

I have a simple solution with one Form (not the Telerik version). I also have one RadGridView and one Windows DataGridView.

Doesn't matter what I try in the conversion wizard, VS2022 crashes. I tried selecting a subset of files to convert (the list of files never displays), tried selecting only DataGridView and tried selecting all control types. All result in VS crashing with no conversion having taken place.

I searched the Telerik Knowledge Base and the best I could find seems to indicate VS2019 is a requirement. And if you suffer from crashes, that solution only goes back to VS2017. I downloaded the converter and I can only select VS2017.

https://docs.telerik.com/devtools/winforms/winforms-converter/requirements

https://docs.telerik.com/devtools/winforms/knowledge-base/converter-exception

I tried attaching the ZIP file but it is 33MB and that is too large. The solution only has one form and two grids. With very basic hard-coded data to load (which I took from a Telerik tutorial).

 

Second: Adding a RadGridView to our existing .NET 8 WinForms project results in VS2022 freezing when I try to rebuild the solution.

I can't include code for this one. What I did was add a NuGet package to: Include="UI.for.WinForms.AllControls.Net80.Trial" Version="2024.2.514"...

I dragged a RadGridiew onto an existing Form that had a DataGridView. I then copied whatever loading I do for the DataGridView and bind the same List (around 100 rows) to both grids.

If I try to rebuild the solution, once it gets to the project containing the RadGridView VS2022 will freeze.

However if I run the solution, I see the grid loaded an populated

 

Thanks for any insights.

Is it possible to create a new Radform when using a vb.net and .net 8 project?  When I attempt to create a new form, there are only .net framework templates shown

Hi 

I have a RadGridView and after updating a cell value I save the scroll (horizontal and vertical) values to set the same position after a refresh.

The problem: when I update a cell, after setting the same values for the horizontal and vertical scrolls, the current cell is placed to the right corner of the grid (image 2). Even if the scroll values are set correctly.

Img1: before changing a cell value

Img2: when the value has changed and the scroll values are set as they were. 

 

Thanks in advanced
