I'm experiencing weird behavior when trying to remove a row using v2023.3.1114. I created a test form in my main app and launch it like this:

Form1 form = new();

form.ShowDialog();

The form populates a grid  by setting the DataSource to a collection of POCOs.

The grid has a a hyperlink column. When the user clicks the column, the goal is to have the clicked row disappear. I'm implementing it like this:

private void gvTaskNotifyType_HyperlinkOpening(object sender, HyperlinkOpeningEventArgs e)

Problem is when the RemoveAt() method is called it throws a Object reference not set to an instance of an object . It may happen the first time or more often the 3rd. It also happens if I use Remove() and pass in a reference to the row object and also if I try to set the IsVisible property to false. The really strange part is that the error doesn't enter the catch handler. Rather, its stops on the form.ShowDialog(); line and breaks there.

Any ideas?

Hello!

I was trying to upgrade several programs to have the font connected to the program size ("dynamic" font). I wasn't able to do it in a simple way because i kept finding problems and i assumed it was some minor telerik object bugs. But then i found out that some of the bugs weren't simple to fix because the fix would impact the program performance. So i created a program from scratch to see if the problem was in my program (i could be doing something wrong since it hd a lot of code) but i came to the conclusion that this problem is actually because of the theme and not mine or the programs fault.

When i use a radgridview and change the font to a higher size (ex: 27) some of the text in the grid won't change if i'm using the theme 'TelerikMetroBlue'. But if i use the default theme 'Office2010Blue' the object works great.

Please check the attached images.

Note: I'm only using a radgridview in this example but the problem was also detected in other objects, like radlistview and radganttview.

Hi Telerik,

I'm using C# and and RadPageView NavigationBar component for my WinForms application.

I think I'll give a background story first.

I implement a RadPageView with NavigationBar, and also implement a search bar between the hamburger menu and the RadPageView items

The item's is populated from a class

The "search menu" is used to filter the displayed menu 

And when I clear the search menu's filter, the RadPageViewItems is re-loaded with the previous class data. But, it takes a long time due to a lot of records (FYI, i have ~1000 menus that equivalent to ~1000 RadPageViewItems)

Is it possible to improve the load speed? Like, maybe, any mechanism that stores the fully loaded menu as a local-storage in RadPageView's function/module that I should call when the search menu is cleared after it has been filled?

Thanks in advance!

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.
