Hi, 

I want to change the Time Button Style of RadDateTimePicker, like mouseover or pressed style.

But i cannot find it in tempalte.

Hello.

Inside the gridview is a hierarchical gridview.

I created a button of the column cell template in the hierarchical grid view.

How to bind this button and how to receive parameters?

Upload a simple example image and source.

<telerik:RadGridView x:Name="xMain"  ItemsSource="{Binding Main}">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn Header="Name"  DataMemberBinding="{Binding Name}"/>
        <telerik:GridViewColumn Header="View" Width="80" HeaderTextAlignment="Center" TextAlignment="Center">
            <telerik:GridViewColumn.CellTemplate>
                <DataTemplate>
                    <telerik:RadButton	Content="MainButton"
										Command="{Binding DataContext.OnClickCommand, RelativeSource={RelativeSource FindAncestor,AncestorType=telerik:RadGridView}}"
										CommandParameter="{Binding}">
                    </telerik:RadButton>
                </DataTemplate>
            </telerik:GridViewColumn.CellTemplate>
        </telerik:GridViewColumn>

        <telerik:RadGridView.ChildTableDefinitions>
        <telerik:GridViewTableDefinition>
            <telerik:GridViewTableDefinition.Relation>
                <telerik:PropertyRelation ParentPropertyName="Subs" />
            </telerik:GridViewTableDefinition.Relation>
        </telerik:GridViewTableDefinition>
    </telerik:RadGridView.ChildTableDefinitions>

    <telerik:RadGridView.HierarchyChildTemplate>
        <DataTemplate>
                <telerik:RadGridView x:Name="xSubs" ItemsSource="{Binding Subs}">
                <telerik:RadGridView.Columns>
                    <telerik:GridViewDataColumn Header="Name"  DataMemberBinding="{Binding Name}"/>
                    <telerik:GridViewColumn Header="View" Width="80" HeaderTextAlignment="Center" TextAlignment="Center">
                        <telerik:GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <telerik:RadButton	Content="SubButton"
													Command="{Binding DataContext.OnClickCommand, RelativeSource={RelativeSource FindAncestor,AncestorType=telerik:RadGridView}}"
													CommandParameter="{Binding}">
                                </telerik:RadButton>
                            </DataTemplate>
                        </telerik:GridViewColumn.CellTemplate>
                    </telerik:GridViewColumn>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>
        </DataTemplate>
    </telerik:RadGridView.HierarchyChildTemplate>
</telerik:RadGridView>

It is bound to the same OnClickCommand and will receive an object to identify it.

(CommandParameter is the selecteditem that is bound to the GridView.)

MainButton working / SubButton not working

I also tried setting Mode=TemplatedParent of RelativeSource and other settings, but couldn't find a solution.

I am using radgridview on my project to display collection of data and I got an exception when I resize column. please find attachment for your reference. Application is also crashed so please help me out from this.

First jpeg : I got an exception whenever I tried to resize column

Second jpeg : I got an exception whenever I do mouse double click on radgridview row

Thanks & Regards

Hi,

I am using radribboncombobox to display toolbar.we want to display combobox like shown in image.

last item as default item i.e "manage filters"  in combobox and also other items are grouped as per category "shared" or "personal".

is it possible?

How to do it using template.?

I have a RadSplitContainer docking in an application and when I do the following it either returns DockedLeft or DockedBottom, however I can see that's not correct:

var docking = RadDocking.GetDockState(container)

If I ask for the width and height, I get fixed numbers, not the actual size of the container:

var width = container.ActualWidth;
var height = container.ActualHeight;

This question seems related to .Net, but as I am using Telerik UI WPF noXaml 2021 R2 assemblies. I have doubt that Telerik controls might causing this error.

I have published .Net 5 SCD x-86 wpf application on client machine which has win 7 OS. As client machines are outdated, therefore we provided them self contained deployment. 

Our application is importing Telerik UI for WPF noXaml 2021 R2 assemblies, and  using Font Glyph. FontResources.xaml is imported at application startup. Other than that application is using default fonts.

As following errors shows, application is unable to create font (may be font not found/ corrupted fonts), and I guess Telerik Font Glyph is using fonts which is not available in older OS like Win 7.

When I import html document to HtmlFormatProvider, I noticed empty line at beginning of each paragraph. When I exported same document as html document. I found empty paragraph is added, which causing extra spacing. Our challenge is to remove such extra spaces, so that all text in columns are same aligned. 

Following is actual document content

<body><p class="NormalWeb "><span class="s_B0779B8D">some text here</span></p><p class="Normal ">&nbsp;</p></body>

While following is generated html document (First para is not part of actual document. and same rendered in richtextbox editor. which adds extra space on top)

<p class="NormalWeb ">
	<span class="s_DED8E654"> </span>
</p>
<p class="NormalWeb ">
	<span class="s_BCF031D1">some text here</span>
</p>
<p class="Normal ">&nbsp;</p>

I am using following code to import html into editor

using (Stream input = new MemoryStream(Encoding.Default.GetBytes(html)))
{
	HtmlFormatProvider provider = new HtmlFormatProvider();
	provider.ImportSettings = new HtmlImportSettings
	{
		UseDefaultStylesheetForFontProperties = false,
		UseHtmlHeadingStyles = false
	};
	RadDocument document = provider.Import(input);
	editor.Document = document;

	editor.Document.StyleRepository["NormalWeb"].ParagraphProperties.SpacingBefore = 0;
	editor.Document.StyleRepository["NormalWeb"].ParagraphProperties.SpacingAfter = 0;
	editor.Document.StyleRepository["NormalWeb"].ParagraphProperties.AutomaticSpacingAfter = false;

}

For reference I am attaching actual html document, exported html document and rendering in user interface.
