This is a pretty minor issue but the #FF808080 gray appears twice in the default color picker (once at the bottom of first column and once at top of 2nd column) which can lead to a little strangeness.

If you start the color picker with this color selected, it will show both boxes as selected.


The other strangeness I was able to duplicate in the WPF demos (R1 2022SP1) is if I have the 2nd column box gray selected and close the color picker, then when I reopen it the gray at the bottom of the 1st column will be selected.

So start with this:

Click gray at bottom of 1st column, then reopen the screen. The box at the top of the 2nd color will remain selected.

There is a little bit of strangeness too when you have that shade of gray selected and then you click down into one of the "standard colors", it appears to leave the selected border around the original gray color (but does correctly put the selected border around the standard color).


Am I misinterpreting this or is this a bug?

Hello everyone,

I read the most topics with a similiar problem but nothing had worked for me.

I use WPF with MVVM and have a RadGridView. The binding from my Xaml code is with a button and a CommandParameter that passes the RadGridView to my method.

The Code looks like this

private void LoadData(object obj)
{
    RadGridView rad = obj as RadGridView;
    
    GridViewDataColumn col = new GridViewDataColumn();
    col.DataMemberBinding = new System.Windows.Data.Binding("Name");
    col.Header = "Name";

    rad.Columns.Add(col);

    //How to add now a new row to this?
}

How can I add now a new Raw with code? Something like rad.Rows.Add() does not exist.

Hope anybody can help me :-)

Hi Team

We are facing frequent more bottom margin issue in RadTreeView with TreeVirtualizationMode="Hierarchical".

There is two level of grouping like parent, child and grandchild. With Hierarchical mode it is happening frequently. But with Recyling and Standard mode it is not happening but the performace is not good. So it is not helping right now.

Tried to adjuest the padding, margins of TreeViewPanel. Nothing helpped. And the number of grand child count is dynamic so cannot assign Height as well.

Need some suggestion. Thanks in advance!

Eg.

Parent A (Expander)

     Child A (Expander)

          Grandchild A (Content)

          Grandchild B (Content)

-----------------------------

----More Blank Space----

------------------------------

Parent B (Expander)

Code

<telerik:RadTreeView x:Name="SearchResultTreeView"
                                     BorderThickness="0"
                                     PreviewKeyDown="SearchResultTreeView_PreviewKeyDown"
                                     telerik:RadTreeViewItem.Selected="SearchResultTreeView_Selected"
                                     ScrollViewer.HorizontalScrollBarVisibility="Disabled"
                                     IsVirtualizing="True" 
                                     telerik:TreeViewPanel.TreeVirtualizationMode="Hierarchical"
                                     PreviewMouseLeftButtonDown="SearchResultTreeView_PreviewMouseLeftButtonDown" 
                                     Margin="0,-1,-1,0" ItemsSource="{Binding MyDummyCollectionView}"
                                     Background="{x:Null}" 
                                     BorderBrush="{x:Null}">

Hello,

I am using the CardView-Control. Is there an event when the user expands/collapses a card?

Hello,

I'm using a custom SettingsPane based on the one you developped (Telerik\UI for WPF R2 2017\Themes.Implicit\WPF40\Windows7\Themes). This pane is used to customize all of the shapes (basic RadShapes and custom shapes) in a RadDiagram.

In this pane, there is a tab (it content is a UserControl) which allows the user to add values (from a RadGridView) to a serie in a RadChart (ScatterChart). The RadGridView allows the copy/paste functionnality to paste some values from Excel (for example).

However, I have a strange behavior about the focus: if I open the pane and the dedicated tab, I go to Excel to copy the data, click on the RadGridView before paste the data, then the main window and the pane don't take the focus. On the contrary, if I copy the data before opening the pane and the tab, there aren't any problems with the focus, the pasting is correctly done.

When the problem occurs, we can see that the main window header is light grey, to indicate that it doesn't have the focus.

Do you know something about this behavior? Do you have any solution? 

Many thanks.

Valentin.

Hello,

I would like to know if there is a way to customize (or alter) the RadGridView-Row Indicator to function more like the row indicator in Excel that supports Selection of rows and Automatic Row Numeration?

Or perhaps any way to set a Custom Row Indicator in a Custom RadGridView?

thank you,

Patrick

I want to be able to restrict the user to entering only hex values in RadGridView rows.

Also, ideally the control creates a single space between hex values.

Any ideas?

Thank you in advance.

Example : 41 78 FF FD

<telerik:RadGridView
                    AutoGenerateColumns="False"
                    CanUserFreezeColumns="False"
                    CanUserResizeColumns="False"
                    CanUserSortColumns="True"
                    CanUserSortGroups="False"
                    GroupRenderMode="Flat"
                    IsReadOnly="True"
                    RowIndicatorVisibility="Collapsed"
                    ShouldCloseFilteringPopupOnKeyboardFocusChanged="True"
                    ShowColumnSortIndexes="True"
                    ItemsSource="{Binding Tasks}">
                    <telerik:RadGridView.Columns>
                        <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name" />
                        <telerik:GridViewDataColumn DataMemberBinding="{Binding Phone}" Header="Phone" />
                    </telerik:RadGridView.Columns>

  </telerik:RadGridView>

Hello,

I'm developing an application that is based on fluent theme but should not use the ripple effect.

Therefore I followed instuctions in Fluent Theme article and placed in resouces of my MainWindow.xaml

<Window.Resources>
        <Style TargetType="mat:FluentControl" >
            <Setter Property="IsRippleEnabled" Value="False" />
        </Style>
</Window.Resources>

Basically this is working fine. On controls like Buttons or NavigationView the effect disappears. Unfortunately I noticed, that in RadListBox the ripple effect is still active when mouse is over an item of the list.

I attached a small example. It contains just a listbox and a button. Fluent theme is set and ripple should be disabled. For button it works fine. Listbox items still showing the effect.

How can I disable the ripple effect also for listbox items?

Thanks and regards

Hi there,

I am looking for a way to programmatically deselect the current selected row by clicking on it. I do not wish to use the ToggleRowDetailsColumn. 

Here is the logic I wish to implement:

if (clickedItem == this.gridView.SelectedItem)
{
    this.gridView.SelectedItems.Clear();
}
else
{
    this.gridView.SelectedItem = clickedItem;
}

Thanks
