Hi,

I have created a RadGridView with a couple of columns (one of them being GridViewSelectColumn). I have also created a GroupDescriptor with GroupHeaderTemplate and I would like to add a GridViewCheckBox to the GroupHeaderTemplate, so I can select all items in a particular group by one click, however, the GridViewCheckBox is not enabled. I tried different properties on the control, but none of them works for me. 

If I add just a CheckBox then it works, but it does not have the style I need and I would not like to reproduce the Style already present on GridViewSelectColumn.

Can you advise how to enable the GridViewCheckBox ?

Thanks

Hi,

I an using RadMaskedCurrencyInput control for taking number from input its work fine for using English Keyboard. The problem is when I change the system language to Japanese and enter number using NumPad , instead of new value replace with entered one, new value is concatenate with previous value. Like if 415 is already entered, I switch the Keyboard to Japanese  and select the previous entered value and type new number 325, Predication window is open and choose the number 325. After's electing value, our RadMaskedCurrencyInput  shows 325415 value instead of 325.
Please help me to resolve this.


Thanks in Advance.

Hi,

I use a RadGridView to display a collection of object. I use it for display only, no user input needed except for a button in the last column.

Why I use this control for such display and not a ListBox: a ListBox would require me to create an ItemTemplate but I need to keep constant columns width between my object properties so I can have a consistent alignment for all items. Also the columns should always be set to the largest control within it.

I remove most features that makes it look like a table: 

<telerik:RadGridView x:Name="radGridView"
                                 ItemsSource="{Binding Items}"
                                 ShowColumnHeaders="False" ShowGroupPanel="False"
                                 RowIndicatorVisibility="Collapsed"
                                 AlternateRowBackground="Transparent"
                                 AutoGenerateColumns="False"
                                 GridLinesVisibility="None"
                                 CanUserFreezeColumns="False" CanUserReorderColumns="False"
                                 CanUserSelectColumns="False">

I also set CanUserSelect="False" and  IsSynchronizedWithCurrentItem="False" but that didn't seem to work...

The last step would be to remove the selection and its display. I would like to remove the focus and color change when click on a row. I tried to set IsHitTestVisible = "False" but it prevent me to use my buttons in the last column.. 

                                

Any suggestions ?

Thank you for your help

An error occurred while running the wizard.

When I execute this code to open a window in the application, I see in the Diagnostic Tool that the window is cleaned

var dialog = new TestWindow();
dialog.Show();

<Window x:Class="BusinessModules.WfmModule.Views.TestWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        mc:Ignorable="d"
       Height="450" Width="800">
    <Grid/>
</Window>

public partial class TestWindow
{
    public TestWindow()
    {
        InitializeComponent();
    }
}

 

But if I change to RadWindow

 

<telerik:RadWindow x:Class="BusinessModules.WfmModule.Views.TestWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        mc:Ignorable="d"
       Height="450" Width="800">
    <Grid/>
</telerik:RadWindow>

I see that the window is not cleaned

This is after I opened it 18 times and of course closed all the windows

 

Would appreciate help

When you use a MentionContext on a RadRichTextBox and you are on the last line of the text box, it does not pop open a Mention Context Menu when using the Context Character.  You have to hit a return to expand the box, and then move up a line, and then use the mention Character. 

Am I missing something or was this done by design? 

Is there a way to trick it into thinking it isn't the last line? 

Can it be fixed to possibly open upward instead of downward?  Since my example is only one line, an upward solution wouldn't work for me either.

Hello,

 

I've updated my WPF project to 2022 R2 package, and after the update, all of the RadButtons became perfectly square, despite them having rounded corners.

Am I missing something? Is is because of the update? I did not change anything with the theme (and neither anything else).

Right now, my trackball information appears directly over the mouse point.  It obscures the trackball line and the point on the plot about which info is being shown.  Like this:





What I would like is some sort of "smart" placement that puts the tip on one side or the other -- or even above, based on how much room is available.  Here's a crude example I hacked up merely by hard-coding the margin to be 100 pixels offset

            <tk:RadCartesianChart.TrackBallInfoStyle> 
                <Style TargetType="{x:Type tk:TrackBallInfoControl}"> 
                    <Setter Property="Margin" Value="100 0 0 0"/>
                </Style> 
            </tk:RadCartesianChart.TrackBallInfoStyle> 
The result is better but obviously does nothing to account for the actual font size (which could make 100 pixels not enough or too much) or location of the mouse on the control.  If I'm on the far right side of my chart, I want this info tip to move to the left so I can still read all of it.



As you can see, I've customized the TrackBallInfoTemplate quite a bit.   Maybe this option already existed and I broke it/neglected to set it in my customizations?  I cannot see any properties on the control that might let me set it.

Does anything like this exist?  Or do I need a really complicated converter...?

how can I specify MultipleSelectionBoxTemplate which i can access properties of selected items ?

i have an employee class 

    public class Employee {
    public string Firstname {get;set;}
    public string Lastname {get;set;}
    }



I am using Telerik radCombobox in my wpf application to display list of employee 

              <telerik:RadComboBox x:Name="radComboBox"
                                     Width="200" 
                                     AllowMultipleSelection="True" 
                                     ItemsSource="{Binding Path=EmployeeList}"  
                                     >

                    <telerik:RadComboBox.ItemTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Path=Lastname}" />
                        </DataTemplate>
                    </telerik:RadComboBox.ItemTemplate>

note: this code simplified , i have to use ItemTemplate  because i set textblock style based on some condition 


this works fine for item template  but when i select an item the display text in combobox show  full name of Employee class (namespace + class name ) not the Lastname
i tried 

             <telerik:RadComboBox.MultipleSelectionBoxTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Path=Lastname}" />
                        </DataTemplate>
                    </telerik:RadComboBox.MultipleSelectionBoxTemplate>


i get no result , the combobox displayvalue of selected item is always empty.

i tried another solution 

                    <telerik:RadComboBox.MultipleSelectionBoxTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Path=SelectedItems,Converter={StaticResource SelectionToCustomStringCoverter}}" />
                        </DataTemplate>
                    </telerik:RadComboBox.MultipleSelectionBoxTemplate>

this neither work , the converter always execute at first selection 

this is really crazy spending 4 hours to figure out a simple thing , 
so my question is how can i specify MultipleSelectionBoxTemplate which i can access properties of selected items .
