Hello together,
I have previously a long peace of code to make a listview bound to a Datasource with all calendar weeks in a range. On Click on first level a listview was loaded under the clicked week with all dates in this week. The color of each week or day was based on the 'Farbe'. A calculated property based on plan and reality.
If the day was completely set to 0 plan, it was disabled, so it could'nt be cklicked anymore.
I now wanted to achieve the same, maybe simplier with a PanelBar. But I have to problem, I don't get the color and disable to work.
I have seta hierarchical dataTemplate as Itemtemplate and of course set the Itemsource in Code behind.
The Problem is, if I set the color of a Stackpanel or something else in the Template the color not affects the background of the expander and everything else.
I tried to set a PanelBarItem as Template but there I have a visual and clickable second object in my normal Item, plus the background not affects anything.
I then a project where someone set ItemCOntainerStyle and ItemStyle, but if I do this my whole PanelBar is empty.
Here is my old listview:

Hi,
I have a program that imitates a physical sheet of paper, with an area that the user can input information. For the input area I'm using a RichTextBox, so the user can paste images, format etc. However, as the page is to be printed on a single piece of paper I want to limit the amount the user can enter. I've disabled the scrollbars so the user cannot scroll up and down, but they can still keep typing as if the document was infinite and the text just disappears. Is there any way to limit the input to only the visible area?

Hi
I am trying to find a solution for changing the color of RadGridView based on the value. In "CellStyleSelector" example I have to define what the style is but in my case the background color can be one of many colors .Cell Background becomes darker shades of Red if value increase , darker shades of green when value goes below 0 and vice versa. I am unable to figure out a way to do it.

Hi,
I have a dashboard with 3 RadCartesianCharts (2 bar charts, 1 line chart) all based on date values for category bindings and numeric values for value bindings.
Both the date values and the value values can vary considerably depending on filters set, so I set up value converters to dynamically adjust the axis labels and tooltips accordingly.
I was successful with all the horizontal axis and tooltips, but not with the y-axis values.
My goal is to adjust the y-axis values based on the size of the values, i.e. thousands vs millions vs billions. I use the following code to properly format the tooltips:
double measureValue = double.Parse(value.ToString());
if (measureValue > 999999999 || measureValue < -999999999)
{
formatString = "0,,,.###B";
}
else if (measureValue > 999999 || measureValue < -999999)
{
formatString = "0,,.##M";
}

Our customer is using our application (using RadMap) with a custom tiled data source to a remote map data source across a very slow network. Can you tell me:
1. What timeout is used for web requests to the map data source? (I believe the default timeout for WebRequest is 100 seconds)
2. Is it possible to change the timeout on the web requests for tiles?
3. What happens if a tile request times-out? Our customer suspects that the Telerik code is caching the timed-out tile response - is that true?
We are currently using Telerik v2019.1.116.45
Thanks

Hi together,
I have previously used the following lines to get the MaskedTextInput to wrapp the text.
I have no installed the last update (R3) and now it says: "The object reference is not declared onto a object instance."
The code still works but in the designer it marks it as wrong and doesn't update the preview anymore.
If I let the BasedOn apart it shows everything as it should bot the code not works anymore as it should. So the MaskedInput is empty and I can't click it anymore.
Without Wrapping the too long lines, well, are too long.
<telerik:RadMaskedTextInput.TextBoxStyle>
<Style TargetType="maskedInput:PreviewInputTextBox" BasedOn="{StaticResource MaskedInputTextBoxStyle}">
<Setter Property="TextWrapping" Value="Wrap" />
<Setter Property="AcceptsReturn" Value="True" />
</Style>
</telerik:RadMaskedTextInput.TextBoxStyle>
Greetings,

Hey,
I am trying to create a Telerik Data Grid (RadGridView) which styles each line dynamically based on some data triggers. I am using VS2019, .NET 4.6 WPF with Telerik 2019.2 NOXAML.
As I did not know how I searched the web (including this forum) and identified a basic solution. Using
<telerik:RadGridView.RowStyle>
<Style TargetType="telerik:GridViewRow">
<Setter Property="Background" Value="Red"/>
<Setter Property="Foreground" Value="White"/>
</Style>
</telerik:RadGridView.RowStyle>
I should be able to style every row red/white (for starters ...). This is from the example here (https://docs.telerik.com/devtools/wpf/controls/radgridview/styles-and-templates/styling-a-row) which is not really good because it does not tell me HOW to define it exactly on my grid. However I also found an example from the forum from 2010 (https://www.telerik.com/forums/setting-radgridview-row-background-color-based-on-the-value-of-a-column-in-the-row) which uses the styling as you see above. The example works however my grid simply shows "nothing" as soon as I use the style definition.
This is my grid which I simplified for you:
App.xml:
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8Touch;component/Themes/System.Windows.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8Touch;component/Themes/Telerik.Windows.Controls.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8Touch;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8Touch;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
Grid.xml:
<telerik:RadGridView ItemsSource="{Binding MyObservableList}" AutoGenerateColumns="False" RowIndicatorVisibility="Collapsed">
<telerik:RadGridView.RowStyle>
<Style TargetType="telerik:GridViewRow">
<Setter Property="Background" Value="Red"/>
<Setter Property="Foreground" Value="White"/>
</Style>
</telerik:RadGridView.RowStyle>
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn DataMemberBinding="{Binding idx}" Header="ID" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Description}" Header="Description" />
</telerik:RadGridView.Columns>
</telerik:RadGridView>
