I am working on a Windows Forms Application that load and print PDF document then unload that document  and load new one, but when i call unloadDocument() no new document was loaded :

                   RadPdfViewer rViewer = new RadPdfViewer();
                    rViewer.DocumentLoaded += RViewer_DocumentLoaded;
                    rViewer.LoadDocument(Filepath);
                    rViewer.LoadElementTree();
                    Application.DoEvents();
                    rViewer.PdfViewerElement.StopWaiting();
                    if (rViewer.IsLoaded)
                    { rViewer.UnloadDocument(); }

after unloadde the document i cannot load new PDF doccument?

Hi,

I want to hide some columns of the table I received from Excel on RadGridView.

Hi,

We are using Telerik UI WinForms in our project. Current built-in themes are not suitable for our project requirements. We need Visual Studio 2019 Theme for UI WinForms.

As mentioned in the Telerik blog, the latest R3 2019 release of Telerik UI for WPF and Telerik UI for Silverlight is having Visual Studio 2019 Theme.

When can we expect Visual Studio 2019 Theme for UI WinForms? 

Hi, I would like to use the conversion tool to convert a WinForms project to Telerik controls. Unfortunately the menu item is not showing up for me. See attached screenshot. 

The project to be converted does include a reference to System.Windows.Forms. I am using VS2019 with the latest Telerik Winforms release. 

Thanks,

-Lou

I would like to request 2 features/properties:

1. Disable going back to the days on year editing end (hacked here by the SelectFirstItem() override).
2. Enable inserting number of days that is currently more than the allowed days in the month by adding one month (hacked by the HandleKeyPressDay() override and MyDayLogic())
   • the date set is 15.09.2019, we start writing the date 31.12.2019. Currently you have to change the months first than the days
   • i guess this is a problem for formats with days first but it is a problem

 

public class MyMaskDateTimeProvider : MaskDateTimeProvider
{
public MyMaskDateTimeProvider(string mask, CultureInfo culture, RadMaskedEditBoxElement owner)
: base(mask, culture, owner)
{
this.AutoSelectNextPart = true;
}

public override void SelectFirstItem() { } //base.SelectFirstItem(); //we do not want to go back to the days after the year part

protected override void HandleKeyPressDay(MaskPart part, KeyPressEventArgs e)
{
if(!int.TryParse(e.KeyChar.ToString(), out int result))
return;
string str = part.value.ToString();
int num1 = 0;
int num2;
if(part.hasZero)
{
if(num1 < part.min
|| num1 > part.max)
{
num2 = result;
}
else
{
if(str.Length > 1)
str = str.Substring(1);
num2 = int.Parse(str + e.KeyChar);
}
}
else
{
if(str.Length > 1)
str = str.Substring(1);
num2 = int.Parse(str + e.KeyChar);
}

if(part.day)
{
MyDayLogic(part, num2, result);
}
else
{
part.value = num2 < part.min || num2 > part.max
? result
: num2;
}

part.hasZero = result == 0;
}

private void MyDayLogic(MaskPart part, int num2, int result)
{
//logic for not continuing when changing days and current set month has less days then days needed, when that happens add one month to the current
if((num2 < part.min)
|| (num2 > part.max))
{
if((num2 > part.min)
&& (num2 <= 31))
{
SelectNextEditableItem();
Up(this.List[this.SelectedItemIndex], this.MinDate, this.MaxDate);
SelectPrevEditableItem();
SelectNextEditableItem();
part.value = num2;
}
else
{
part.value = result;
}
}
else
{
part.value = num2;
}
}
}

Hi,

 

It would be cool if we had a Material Dark Theme,

More and more we see clients requesting this from our apps since Google has popularized the trend now.

 

Thanks

The bug can be reproduced like this:

- Launch the "Demo Application - Telerik UI for WinForms R1 2019 SP1" provided with the control suite.

- Choose "Explore all controls", "List control", "Settings"

- In the "Settings panel", set "Selection Mode" to "MultiSimple"

- In the "Themes" panel, choose "Office2013Light"

- click on the second item, then the third, then the fourth to select --> OK

- click on the second item to unselect it --> Not OK, the list isn't refreshed accordingly

- click on the third item to unselect it --> Not OK, the second item is properly unselected but the third one is still selected

The new series will be similar to the RadarColumnSeries which is already available. https://docs.telerik.com/devtools/aspnet-ajax/controls/htmlchart/chart-types/polar-chart

Implement interactive API Reference in the form of a class hierarchy diagram. Allow navigation to the base classes or implemented interfaces, as well as to any child members. Include the API documentation of each member/class, so that users can quickly navigate the API on the site. 

Add Office 2016 theme to the WinForms suite.

This would allow switching the focus between form field controls by using the Tab key.

Add grouping to the navigation view like attached

Dear,

 

would be greate a Dynamic Theme, when we could change all colors from the theme programatically, using a XML to store the custom specification.

 

Inclusive, all themes could be turned into a Dynamic theme.

 

Best regards,

 

Jeff

Dear,

 

I'd like suggest a theme based on CrystalDark with all lines removed, totally flat.

 

Best,

 

Jeff

When one performs a pan operation the axis minimum and maximum should be automatically adjusted. See https://www.okex.com/market?product=btt_usdt

Use attached to reproduce:

1. Click the button

2. Change the tab and go back to the diagram

Workaround:

Add the layout before showing the form

Currently, the DashStyle cannot be changed.
