Hi,

I am using RadScheduleView for WPF. While trying to schedule appointments in the appointment dialog, I would like to get the date displayed as  12 Apr 2020 in date picker . However after setting Display format as Long, it gets displayed as 12 April 2010. I require month to be displayed in 3 letter format and should work in every region. Please suggest. If I set custom format, will it work correct depending on the region.?

Thanks,

Divya

Hi to all,

I configured a Listbox with single Group, but if I change a GroupStyle, Group item not longer appears.

my XAML/C# code is this, and I attached a screenshots (where I put a red rectangle, it not shows my value), where I wrong?

Hi, good morning

I'm trying to change the theme to a RadOpenFileDialog, but I can't do it,

I've used these directions:

 Telerik.WinControls.UI.RadOpenFileDialog opfDialog = new Telerik.WinControls.UI.RadOpenFileDialog();
 opfDialog.OpenFileDialogForm.StartPosition = FormStartPosition.CenterScreen;
 opfDialog.OpenFileDialogForm.ThemeName = "Fluent";

StartPosition if it works, but ThemeName doesn't.

Could you help me?

Hi

currently i'm trying to integrate Intellisense support to rad richtextbox. i was able to display word list when press Ctrl+Space. but could not replace the word. is there any one who try such a thing. i have attached a screen shot which was develop using visual studio richtextbox. can not use that code for RadRichTextBox.

Hi I need to scale an image so that it fills all the empty space in a page. For this I am trying to find the remaining height of the page after some elements are inserted in it. I am using the following code:

The problem is that position.Location.Y does't return a value in pixels. For example when my page is filed with text it returns 173.8107 but the height of the page is 1056. 

How to get position of last element in RadDocument in pixels?

I have a CartesianCustomAnnotation on my chart that  draws an ellipse.  The ellipse must cover the same amount of chart coordinates (millimeters) in X and Y.  Since ellipse height and width are pixels, I had to bind them with a MultiConverter that uses the chart's ConvertDataToPoint function to convert to pixels   It generally works well.

But if I change Vertical/Horizontal axes Minimum/Maximum values in code-behind (to achieve Equal-Scale effect I asked you about), even though my binding gets invoked and calls ConvertDataToPoint agin, the pixel values returned do NOT reflect the chart new layout.  I'll get values representing the old axis min/max values and they'll look terrible with the new scaling

But then, if I do anything at all to force another update of the binding, suddenly, the values returned will look great again.  Even if the change does not alter the underlying values in any meaningful way.

It's almost as the chart's layout code needs for a UI update happen on the control before ConvertDataToPoint will start returning numbers appropriate to the new axes min/max values.

Is there any truth to do this?  If I change an axis max/min, do I need to do something (force some layout/update or something) before calling ConvertDataToPoint?    Or is there some chart/axis property I should be binding to instead of what I'm using (see below)

Note that I've dumped the numbers going into and out of the converter.  They're identical inputs, but completely different outputs from ConvertDataToPoint from when I first change the properties vs when I force a manual update.

Here is the converter

Here is the the  ContentTemplate where bind the ellipse height and width as I describe.  I've only shown the relevant part of the annotation style

I've attached 3 images to show you what I see.  

1. The first attachment ("Correct-Normal-Scale.png") shows the chart as initially loaded.  The Ellipse is skewed horizontally because the chart axes are not equal scale.   But I'm using one size for both X and Y

Here is what my converter dumps for this.  The ellipse is correctly much wider than tall

    length 2.18513189968 => xWidth 516.7183886108953
    length 2.18513189968 => yHeight 48.07290179295998


2. The second attachment ("Incorrect-Equal-Scale.png") shows how it looks right after I check my "Equal Scale" checkbox at the bottom.  This causes me to manually set the axes min/max values (notice how they've changed).   Even though the X axis has changed dramatically, the ellipse remains skewed horizontally.  It should be a circle.

Here is what my converter dumps for this change.  Note that X hasn't changed much.  Y has not changed at all

    length 2.18513189968 => xWidth 503.74066305424367
    length 2.18513189968 => yHeight 48.07290179295998

3. Finally, I manually move the blue region just a tiny bit. This causes the binding to be reevaluated.   The 3rd Attachment ("Correct-Equal-Scale.png") shows how it looks right after.   Notice how the ellipse is now a perfect circle as it should have been. 

Here is what my converter dumps.  Notice how almost exactly the same input length value now produces identical width and height pixel values.

length 2.184046088752083 => xWidth 61.02891091119042
length 2.184046088752083 => yHeight 61.15329048505832

What I'd like to do is to be able to set it so the amount of text displayed in the columns is fixed and when the grid is resized the size of the font changes to keep the text displayed in each row fixed while having the number of rows shown vary as needed.

Using your Binding to 1 Million records Sample to show what I want, I took a screenshot stretched the grid by 50% in height and width to simulate text enlarging
as the window was widened, and then cropped out 5.5 of the 17 rows of data so that the number of rows visible was reduced because the height wasn't changed.

I am doing something very simple. I am trying to apply a simple style to a DateTimePicker.  Basically, if I use the line 

CalendarStyle="{StaticResource calendarStyle}", the drop down calendar doesn't show up. If I remove the line, the calendar works as expected. I'm using runtime version v4.0.30319, description is Progress® Telerik® UI for WPF. Here is the xaml:

<Window x:Class="RadDatePicker.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
  xmlns:local="clr-namespace:RadDatePicker"
        Title="MainWindow" Height="350" Width="935">
    <Window.Resources>
        <Style x:Key="calendarStyle" TargetType="telerik:RadCalendar">
            <Setter Property="AreWeekNumbersVisible" Value="True" />
        </Style>
    </Window.Resources>
    <Grid Height="207">
        <Border CornerRadius="6" >
            <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
                <telerik:RadDatePicker x:Name="datePicker"
                   InputMode="DatePicker"
                   DisplayFormat="Short"
                   DateTimeWatermarkContent="Enter date"
                   DateSelectionMode="Day"
                   CalendarStyle="{StaticResource calendarStyle}" />
            </StackPanel>
        </Border>
    </Grid>
</Window>

Hi, 

     I'm develpoing a WPF application using GridView. In my scenario, some cells need to be merged Vertically, some cells while, need to be merged Horizontally. But the MergedCellsDirection property can not be set to two orientations at one time. Is any suggestions or mechanism for this problem?

     best regards
