Hi,

I want to extend the RadGridView control, so I do "public class TkGrid : Telerik.WinControls.UI.RadGridView {}"

How do I apply a theme to TkGrid control ? I set "ThemeResolutionService.ApplicationThemeName = "FluentDark" but this doesn't work.

I attached a small project where I have one TkGrid and one RadGridView. On top of form there is a dropdown from where you can change the theme

When I do this, TkGrid is not displayed with the new theme (this works for RadGridView)

p.s. I also added a custom Button, TkButton inherited from RadButton. When I change the theme, the look of TkButton is changed, so this is ok

Hi,

I want to add a MultiComboBoxColumn to a GridView

is it possible to define the columns for this MultiComboBox at design time (in Property Builder editor of Grid) ?

Hello, I encountered a bug with PropertyGrid when an object property is null.

But it only happens when the object has a simple property, a simple list, and a complex list with a custom control.

I'm attaching a sample project.

To reproduce this bug, run the project and hit the sort button or enter any search strings.

By default, the ImagePrimitive in a ribbon button is auto sized. If you want to disable the AutoSize property of the image and specify a specific Size, the AutoSize property gets serialized in the designer, but the Size is not. This leads to missing image after reopening the designer.

After saving the changes and reopening the designer the image is missing since its Size property is not serialized:

Run the attached project and follow the steps in the gif file. As a result the following exception occurs:

System.IO.IOException: 'The process cannot access the file 't_0_0_1.png' because it is being used by another process.'

Code snippet for reproducing the problem:

    Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Me.SongsTableAdapter.Fill(Me.MusicCollectionDataSet.Songs)
        Me.ArtistsTableAdapter.Fill(Me.MusicCollectionDataSet.Artists)
        Me.AlbumsTableAdapter.Fill(Me.MusicCollectionDataSet.Albums)

        AddHandler Me.RadTreeView1.NodeDataBound, AddressOf RadTreeView1_NodeDataBound

        Me.RadTreeView1.DataSource = Me.ArtistsBindingSource
        Me.RadTreeView1.DisplayMember = "ArtistName"
        Me.RadTreeView1.ValueMember = "ArtistID"
        Me.RadTreeView1.RelationBindings.Add(New RelationBinding(Me.AlbumsBindingSource, "AlbumName", "ArtistID", "ArtistID", "AlbumID"))
        Me.RadTreeView1.RelationBindings.Add(New RelationBinding(Me.SongsBindingSource, "SongName", "AlbumID", "AlbumID", "SongID"))
        Me.RadTreeView1.CheckBoxes = True
        Me.RadTreeView1.AutoCheckChildNodes = True
        Me.RadTreeView1.TriStateMode = True
        Me.RadTreeView1.ExpandAll()
    End Sub

    Private Sub RadTreeView1_NodeDataBound(sender As Object, e As RadTreeViewEventArgs)
        If e.Node.Level = 0 Then
            e.Node.CheckType = CheckType.None
        Else
            e.Node.CheckType = CheckType.CheckBox
        End If
    End Sub

Workaround: instead of using the NodeDataBound  event, use the NodeFormatting event to hide the checkboxes for the desired nodes:

    Private Sub RadTreeView1_NodeFormatting(sender As Object, e As TreeNodeFormattingEventArgs)
        If e.Node.Level = 0 Then
            e.NodeElement.ToggleElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed
        Else
            e.NodeElement.ToggleElement.Visibility = Telerik.WinControls.ElementVisibility.Visible
        End If
    End Sub

dear sir ,

i have a problem keydown event does not fire in add new row ?

i want to move to the next cell when i hit Enter key after entering new value and when i reach the last cell of the add new row and type enter the new row will automatically added to the grid....

what's i have to do.....

please any suggest ? thx

I start a new, Winforms .Net Framework 4.7.2 project.
I add the radBarcode to the form, a sample QR code is shown.
I change the Symbology-property to DataMatrix, the sample picture of the barcode is cleared and no barcode is shown. This is also the case when I change the Symbology-property via the control smart menu/tags

And here comes the point: I always inserted my value for the barcode in the Text-property and not in the Value-property (my fault). After playing around and reading the docu I realised that I need to set the Value property. If I do this via smart menu/tag It works fine.

But why does the Value property get cleared by changing the Symbology-Property? If there could be any conflicts between different barcodes, wouldn't it be better to show some infobox, that the value is incompatible to the selected symbology?

Hi Dess,

No problem. Fully understood.

Please find the new questions attached below and kindly get back to the customer Mr Huang (conext.vincent@gmail.com).

Thanks,

Peter

Hi Peggy,

It sounds a bit too complicated for the pre sales engineer. Can you please kindly let me know the license holder email and I will issue a support ticket on his Telerik account so that the developing team can get involved.

Hi Peter,

我們在跟一個客戶討論續約問題，因為如果不續約，當下的版本是否可以一直沿用，因為這套軟體升級不會刪除舊檔案，導致很多問題出來。

因為客戶編輯好專案,也進行發行動作,但是安裝到電腦會發生錯誤,請問要在其他台電腦執行客戶的安裝該如何執行.

請回復技術問題.

軟體下進行模擬可以正常運行.

執行發行後的安裝檔

無法安裝.

附件有錯誤檔案.

Problem: I'd like to filter the properties to be displayed by their category names defined by the Category attribute. Based on the doc here (https://docs.telerik.com/devtools/winforms/controls/propertygrid/features/filtering), my understanding is to add a FilterDescriptor like this: New FilterDescriptor ("Category", FilterOperator.Contains, "some category name"). But it turned out to only filter by property name, not category name. Any misunderstanding or possible issue? Thank you for looking into this.

Reproduce:

1. Define a class like this:

    Private Class TestClass
        <Category("Cat1")> Public Property Property1 As Integer = 1
        <Category("Cat1")> Public Property Property2 As String = "Test 2"
        <Category("Cat2")> Public Property Property3 As String = "Test 3"
    End Class

2. Initialize a RadPropertyGrid in the Form.Load event:

        Dim testObj As New TestClass
        RadPropertyGrid1.EnableFiltering = True
        Dim filter As New FilterDescriptor("Category", FilterOperator.Contains, "2")
        RadPropertyGrid1.FilterDescriptors.Add(filter)
        RadPropertyGrid1.SelectedObject = testObj

3. The right property to be displayed should be Property3, but it turned out to be Property2

Example project: attached.

Thank you team!

The layout on a monitor with 100%:

After moving the form to a monitor with higher than 100% DPI scaling, e.g. 175% or greater:

Once you switch to the first page which contains exactly the same UserControl, the layout is not correct:

Follow the steps:

1.Create an application and add a RadRibbonForm with name RadRibbonForm1.

2. Create a new class with name RadRibbonForm1.Test.cs and make it partial. It should look like a form.

3. Double click the new class. It will open the designer and some code will be generated in the class which prevents the application from building. The attached gif file with RadRibbonForm illustrates better the specific steps.

Hi,

I have a question regarding RadGridView. When I edit a cell in GridView and then click on a button (outside of gridview) immediately (i.e I don't click on another cell to exit edit mode), the Gridview is still edit mode. Please refer to the short video named "Without Using EndEdit()" to easily understand my point here.

In order to exit the edit mode, I try the following code:

    Private Sub CustomGridView_LostFocus(sender As Object, e As EventArgs) Handles Me.LostFocus
        Me.EndEdit()
    End Sub

With this code, the gridview does exit the edit mode when I click on another button. But there is a problem with this method is that afterwards, I cannot edit the cell anymore.  Please refer to the short video named "Using EndEdit()" to better understand the problem.

So my question here is, is there any way that I can exit edit mode when clicking on another button right after editing a cell?

Thank you for your help.

Best regards,

Tran

1. Create a custom property item

2. Enable grouping

3.Scroll up and down

4.NullReferenceException occurs

• I have one main form in which a radcommand bar is defined
• other forms inherits this form and replace the commandbarbuttons in the forms with the commandbar buttons in main form
• Successfully replaced the buttons, but the events are not firing after clicking the button.

main form contains  RadCommandbar with button 'cmdNew' and other form contains  RadCommandbar with  button 'cmdNewR'.

Replaced button cmdNewR by cmdNew using the following function

Protected Sub ReplaceRadCommandBarButtonItem(ByVal ctlOriginal As CommandBarButton, ByVal ctlNew As CommandBarButton)
            Dim owner As RadCommandBarItemsPanel = CType(ctlOriginal.Parent, RadCommandBarItemsPanel)
            Dim originalIndex As Integer = owner.Children.IndexOf(ctlOriginal)
            owner.Children.Remove(ctlOriginal)
            owner.Children.Insert(originalIndex, ctlNew)
End Sub

The cmdNewR button in command bar will replaced by cmdNew. but click event is not hitting

 Private Sub cmdNewR_Click(sender As Object, e As EventArgs) Handles cmdNewR.Click
            NewFileClicked()
        End Sub

Private Sub cmdNew_Click(sender As Object, e As EventArgs)
        NewFileClicked()

 End Sub

Hi Dess,

I have encountered some other issue here. text of the button is not displaying in this case.

I have set DrawText property as true, UseCompatibleTextRendering as true and TextImageRelation as true. still the text is not displaying only the image is showing. Could you please go thruogh the same project again

attaching the previous link https://feedback.telerik.com/winforms/1480197-event-not-firing-in-commandbar-button-in-radcommandbar-button

Thanks
