Hello, 

I have a checkbox in a Telerik GridViewDataColumn with its IsChecked binding set to a data source that could be 1, 0, or Null.

When the value of the data element is 1, it displays a check.

When the value of the data element is 0, it displays an unchecked checkbox.

But when the value of the data element is Null, it displays an X. That's an issue.

How can I change the display to also show an unchecked checkbox when the value is Null? (It needs to look the same way that it looks when the data element value is 0)

Thank you!

I am pasting text which contains invalid characters (example utf8 hex FFFE). Html binding is not workin in this case. I reproduced binding issue in Telerik wpf demo. Where xaml binding is working fine, while html binding is empty.

For reference I am pasting following text into Richtext box editor. which is bound to HTML binder.

hello.

I used the scroll synchronization function in two gridviews through the linked example.
https://www.telerik.com/forums/scrolling-two-grids-f949e02b84ab

Since this is an old version, the ShowSearchPanel property does not exist.

If I put a SearchPanel in "PART_VerticalScrollBar", two objects appear.

When SearchPanel=true, the first is the VerticalScrollBar of SearchPanel, and the second is the VerticalScrollBar of the GridView.

When SearchPanel=false, only VerticalScrollBar of GridView is displayed.

How can I identify the "PART_VerticalScrollBar" of the GridView when the user uses the SearchPanel as a variable? I guess you shouldn't use "LastOrDefault".

Thanks.

Hi,

on the Telerik website the following documentation can be found about Column Groups:

(figure 5 is not included here since it was not necessary)

I don't want the RadGridView to duplicate the column group once the FrozenColumnSplitter has been moved to the first column.
In my case I only have one column group, and I don't want it duplicated if the Frozen Column splitter is moved:

Do you know how I can change this?
Thanks!

Hi,

I am currently working on a RadGridView component where I want the Frozen Columns Splitter to also cover the row for adding new rows to the grid, see picture:

I want the grid splitter to also cover the red part.

Could you advice me on how to accomplish that?

Thanks!

Hi,

We using the Telerik Map component for a production use. The used provider is OpenStreetMap.
A customer contacted us with an issue. He was using Sophos proxy/OpenVPN at his company but he is the only one in the company to have the problem.
No explicit rules are set on the Sophos admin console.
But the problem is not here, explainations:

I took remote control of his PC to see the problem. After a few tries, the tiles on the map were still displayed out of order like a jigsaw puzzle.
I installed Fiddler 4 to see what was going on and if it was a bad request or something else.
My big surprise was that by using Fiddler, the map problem disappeared! Reversely, when quitting the application, the map problem reappeared.

I guess using Fiddler allows the map to time out and allows the map to display correctly.
My customer using a racing machine. All its configuration can be seen in the attachment files.

Do you have a workaround for that?

Thanks in advance for your reply.

Best regards.

Fabien.

I've noticed in the Auto Complete Box if you type a selection (or paste) and then left mouse click off the control the Selected Item will not be populated.

If I type (or paste) a selection and hit the "tab" key it will select the item.

How can I select the item when the user left mouse clicks off the control?

I can easily duplicate this with the "Auto Complete Box | First Look" from the WPF Controls Example.

See the attached pics.

The first example I typed "Respect" into the autocomplete box for Best Music Hit.  I hit the Tab button and the data populated.

The second example I typed "Respect" into the autocomplete box for Best Music Hit.  I then left mouse clicked outside of that control and the data does not populate.

Please advise.

Hi,

I got from the user Location = {90, -12.516352000000095}

and when I try to create the Provider I get an exception that "'∞' is not a valid value for property 'Height'."

At any other point, everything works properly.

I would be happy if you could help me, 

Thanks.

Hi

I want to ask if there is any option to make QueryableEntityCoreCollectionView perform in backgroud with showing some loading icon on grid, cause it has slow performance for loading large DB table?

UI is not responding while loading. With pagging it is better, but we whould like to not use pagging. I was testing QueryableEntityCoreCollectionView on MVVM example: https://docs.telerik.com/devtools/wpf/controls/radentityframeworkcoredatasource/entityframeworkcore-mvvm-usage

Thanks
