Hi All,

I am developing a tool for Autodesk Revit using the pyrevit extension and IronPython. For this, I have implemented a custom control called IntegerUpDown, which I need to use in my tool. I tested the control in Visual Studio, and it works well. However, I am struggling to use my control in pyrevit by referencing it's name space in my main xaml file, considering the structure of my project attached below:

Please check my references:

IntegerUpDown.xaml :

<UserControl 
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             MinWidth="50">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="Auto"/>
        </Grid.ColumnDefinitions>

        <Grid Grid.Column="0">
            <TextBox x:Name="NumericText" Grid.Column="0"
                     Text="0"

Validation of RadWatermarkTextBox - Tooltip DisplayMode doesn't work

Hello. Please give an idea to start with ...

I have RadWatermarkTextBox. And I've added INotifyDataErrorInfo to my VM implementation.

When DisplayMode is Static - I can see validation errors. But When it's Tooltip telerik:ValidationErrorTemplateHelper.DisplayMode="ToolTip"
I can't see.

By the way. if I use static mode I also don't see red bottom border line. And red arrow at top right corner, my error text is just a black font without read rectangle around and etc.

Looks like missing styles. But I can't understand which one. I imported xaml files for Win11 style. I see that there is a definition for RadWatermarkTextBox Validation Styles.

CellValidating ErrorMessage does not show or is invisible.

In my `telerik:RadGridView`, I have configured a `CellValidating="RadGridView_CellValidating"` callback. It successfully catches a validation error, which then invokes this code:

e.IsValid = false;
e.ErrorMessage = "Enter a valid URL with 'https://' or 'http://'";

The cell does properly receive a red border, and what looks like a tool-tip notation in the top right corner. However, unfortunately, I am unable to see the tool-tip, regardless if I hover or click on the tool-tip. What are perhaps the top three to five reasons this might be happening?

It is specifically the "Documentation" column above, which is a `GridViewHyperlinkColumn`, which is failing validation...with no tool-tip showing. To be clear, actually none of the columns have a working or "showable" tool-tip. Even so, here is the code specifically for my "Documentation" column:

    <telerik:GridViewHyperlinkColumn
        IsReadOnly="{Binding IsEditModeWithPermissions, Converter={StaticResource InverseBooleanConverter}}"
        CellStyle="{StaticResource GridViewCellStyleStretch}" IsCustomSortingEnabled="False"
        ValidatesOnDataErrors="InViewMode"
        UniqueName="Documentation"
        MinWidth="80" MaxWidth="350" Width="150"
        DataMemberBinding="{Binding Documentation}"
        Name="DocumentationColumn" Header="Documentation">
        <telerik:GridViewHyperlinkColumn.CellTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding DocumentationFormatted, StringFormat='{}{0}'}"/>
            </DataTemplate>
        </telerik:GridViewHyperlinkColumn.CellTemplate>
        <telerik:GridViewHyperlinkColumn.CellEditTemplate>
            <DataTemplate>
                <telerik:RadComboBox x:Name="DocumentationBox"
                    Text="{Binding Documentation, Mode=TwoWay}" KeyDown="RadComboBox_PreviewKeyDown"
                    IsTextSearchEnabled="True" TextSearchMode="StartsWith" OpenDropDownOnFocus="True"
                    StaysOpenOnEdit="False" Loaded="RadComboBox_Loaded" IsEditable="True" >
                    <telerik:RadComboBox.Resources>
                        <Style TargetType="TextBox">
                            <Setter Property="MaxLength" Value="{Binding DocumentationColumnWidth}" />
                        </Style>
                    </telerik:RadComboBox.Resources>
                </telerik:RadComboBox>
            </DataTemplate>
        </telerik:GridViewHyperlinkColumn.CellEditTemplate>
    </telerik:GridViewHyperlinkColumn>

And here is the RadGridView initial declaration:

    <telerik:RadGridView Grid.Row="1"
        CellValidating="RadGridView_CellValidating"
        BorderThickness="{Binding GridBorderThickness}"

        PreparingCellForEdit="uxGrid_PreparingCellForEdit" Deleted="UxGrid_OnDeleted"

        KeyDown="GridKeyDown"

[Solved] Why do ToolTips not honor the Theme?

I customized my WPF app's Windows8Touch theme with a compete palette of colors -- that is I set up the Windows8TouchPalette at startup before the main windows shows. In my palette, the background is dark and the foreground is light.

I've had it this way for years and it works quite well. But the whenever I set the RadToolTipService.ToolTipContent property on any control using just a string, I get a white background fpr tje text. So I am forced to specifically create a full UI for it or use the ToolTipContentTemplate. It looks like the default settings for that do not honor my colors

Is there some Telerik-specific control type that I can set a default style for that will fix this issue? Kinda like how I can style `RadAlert` or `RadPrompt` for those dialogs?

(Note that I am using the binaries with XAML in them so I use the StyleManager to theme things, if that matters. Where I feel the need I copy the Telerik styles out of your XAML files for my theme and customize them. )

telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True" that works on the RadListBox?

Is there a

telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True" that works on the RadListBox (not only the RadComboBox)?

So a :ComboBoxToolTipHelper.ShowToolTipOnTrimmedText that works on the RadListBox?

Or another way of achieving it on the RadListBox?

Background:

I tried with a behavior on the row data template but it conflicts with the drag and drop by causing exceptions during the drag and drop (but that would incur another question thread). I am just writing this to say i tried this avenue.

Right now my RadLitBox looks as follows:

<telerik:RadListBox x:Name="RLB_Source"
VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
ItemsSource="{Binding SourceSplitList, Mode=TwoWay}"
SelectionMode="Multiple"
telerik:ListBoxSelectedItemsBehavior.SelectedItemsSource="{Binding SelectedSourceItems}"
DisplayMemberPath="Name"
AllowDrop="True"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
ScrollViewer.VerticalScrollBarVisibility="Visible"
Style="{StaticResource RadListBoxStyle}"
telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True"
ToolTipService.ToolTip="{Binding Text, RelativeSource={RelativeSource Self}}"
>

Because of the lines:

telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True"
ToolTipService.ToolTip="{Binding Text, RelativeSource={RelativeSource Self}}"

There is a tool tip showing the text of every RadListBox row - and not only where the text is trimmed.

How is the text trimmed? Short answer: i have a telerik:RadListBoxItem style template where text trimming is set as below:

Here is the entire control template:

</ControlTemplate>

Trimming is set on the TextBlock that appears (implicitly by Telerik) in the Contentpresenter.

The whole styling is below if relevant for answering the question:

My RadListBox has this style:

In the the above style there is an ItemContainerStyle. Here it goes:

RadCartesianChart ScatterPointseries: Tooltip only showing in XamlRenderOptions mode

Hi, trying to speed up the points-plot (around 1000-5000 points)

I can so far conclude that we can only get a tooltip for XamlRenderOptions DefaultVisualsRenderMode="Separate" otw, no tooltip is visible.

I have tried a few options (see below) - but maybe the behavior changes once I change the render mode ?

- XamlRenderOptions DefaultVisualsRenderMode="Batch" -> no tooltip
- (geometrytype not supported by scatterpointseries)
- BitmapRenderOptions -> no tooltip
- Direct2DRenderOptions -> not tooltip

tooltip reactivate

Hi,

I observed that when the tooltip disappears, I need to move out of control before I can see the tooltip again (also in your sample with England map you can see this effect). It is reasonable, but I have a control that display a histogram plot. I could move the mouse over different bar and I would like that the tooltip could show again.
Is there a way to reactivate tooltip without exit from control?

Thank you

Luigi
