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

Changing the preferred width of columns to percentages from the Table Properties dialog actually sets them in pixels.

Steps to reproduce:
1) Insert a table

2) select table column property and set preferred width to 20%

3) press "next column" button and set preferred width to 20% 

4) Go to previous columns 

Expected: Column width is set in percentage.

Actual: Some (or all) columns have width set in pixels.

Hello,

I have already used your ItemFormatting event in my code and implemented it the same way you have provided.

In my code, i have created 7-8 messages and fixed the first msg's timestamp to "6/6/2019 11:53:08 AM" and the remaining messages with timestamp of 2 minutes more than this time. Whenever the event is triggered i wrote a code which compares the timestamp of my message with this timestamp "6/6/2019 11:53:08 AM". Conditionally only the first message falls in this condition and i paint it red, which works well for first time (On load) and then when i scroll my chat, the event unnecessarily paints the remaining msgs too, which should not happen.

I am attaching my .cs file with designer please refer to it, and resolve this asap. Looking forward to your response.

Thanks.

Release R3 2019 (LIB 2019.2.729)

https://docs.telerik.com/devtools/winforms/controls/gridview/filtering/setting-filters-programmatically-(composite-descriptors)

When creating a composite filter descriptor with a value that contains an array of enums, it generates an expression with IN, and an exception is thrown when adding it to the FilterDescriptors on a RadGridView control.

 

Exception Message:

{"The expression contains undefined function call In()."}

 

The expression value is: ([RandomPropertyName] IN (1,3,9) OR [RandomPropertyName] = 10)

 

We have recently upgraded from 2015.2.728.40 (where this worked) to the Feb. 2019 version, then today upgraded to the May 2019 version. The issue remains.

 

The project includes the following Telerik references:

 

Telerik.WinControls

Telerik.WinControls.GridView

Telerik.WinControls.PdfViewer

Telerik.WinControls.RadDock

Telerik.WinControls.RadMarkupEditor

Telerik.WinControls.UI

Telerik.Windows.Documents.Core

Telerik.Windows.Documents.Fixed

Telerik.Windows.Zip

TelerikCommon

When the attribute is defined but no value is set to it, the format provider cannot import the content and throws NullReferenceException.

Release R2 2019 SP1 (LIB 2019.2.527)

ChildRowHeight can be set on the main table element of the control like this:

this.radGridView1.TableElement.ChildRowHeight = 750;

When the grid is in a hierarchy and a parent row is expanded, the inner child template will create a new table element and its ChildRowHeight is 205 which is the default value. It would be expected that the height of the inner table element is initially set as the height of the main table element of the control.

A possible workaround is to handle the ChildViewExpanded event of the grid this way:

private void RadGridView1_ChildViewExpanded(object sender, Telerik.WinControls.UI.ChildViewExpandedEventArgs e)
{
    GridTableElement tableElement = this.radGridView1.CurrentView as GridTableElement;
    if (tableElement != null && e.ParentRow.HierarchyLevel == 1)
    {
        tableElement.ChildRowHeight = 750;
        tableElement.InvalidateMeasure(true);
    }
}
