I'm a Progress OpenEdge developer and found issue with RadGridView using it in a ABL application. I have been able to reproduce the issue outside of the OpenEdge environment, and have attached a project file.

To see the issue, run the app, and scroll down really quickly with scrollbar thumb to the bottom.

You will then get:

System.NullReferenceException
  HResult=0x80004003
  Message=Object reference not set to an instance of an object.

The following notes will explain what we are doing, since it may not be typical.

Hi- When I add a Rad context menu to a RadToolbarForm, the toolbar vanishes from the designer after a build.  This is new behavior because I have other context menus that I had previously added to the form.  If I drag a RadContextMenu from the toolkit, or I copy/paste an existing context menu, the toolbar disappears after a build.  I am running the latest release (2024.1.130) and toolkit config (although this also happens when running the previous Telerik release)

I tried closing the designer before the build and the toolbar still disappears.  Doing a Clean before build has no effect.  This form is inherited from a simple RadToolbar form (no controls except the toolbar).  The toolbar is still listed in the list of controls for the form

Ha!  Just found out what's happening.  It's deleting the toolbar configuration code from the designer code.  Everything below is gone.  If I add it back in, then do anything with the new context menu, like rename it, it gets removed again

Here's my dev environment:

PerformClick method of RadButtonElement is sending next error:

System.InvalidCastException: 'Unable to cast object of type 'System.EventArgs' to type 'System.Windows.Forms.MouseEventArgs'.

Find my code below:

private void btnAddField_Click(object sender, EventArgs e)
{
    RadDiagramShape sourceShape = new RadDiagramShape()
    {
        Text = "source",
        Shape = new RoundRectShape(5),
        BackColor = Color.Red
    };

    sourceShape.Position = new Telerik.Windows.Diagrams.Core.Point(150, 100);
    radDiagram.AddShape(sourceShape);

    sourceShape.IsSelected = true;
    RadButtonElement additionalContent = Telerik.WinControls.UI.Diagrams.Primitives.ItemInformationAdorner.GetAdditionalContent(
                                            this.radDiagram.DiagramElement.ItemInformationAdorner) as RadButtonElement;

    additionalContent.PerformClick();
}

What I want is to display the SettingsPane automatically when adding a RadDiagramShape item in a RadDiagram

Regards

Hi Dinko and Team,

As I mentioned in the previous forum, We need fix for Raddropdownlist.SelectedIndex.

When we set SelectedIndex=5 or some value in selectedIndexchangedEvent then the recursive call is happening for SelectedIndex. So we need to restrict the recursive call for both Raddropdownlist.DataSource as well as Raddropdownlist.SelectedIdex.

  private void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
        {
           fillIndustryProcess1(); // radDropDownList1.DataSource = dt; when we set Datasource the recursive call is occurring
            radDropDownList1.SelectedIdex = 5; // radDropDownList1.SelectedIdex= 5; when we set Datasource the recursive call is occurring

}

Old Forums in which , Telerik team fixed the RadDropDownList .SelectedValue.

Hello support,

here is what happend:

I created a RadFrom with controlls on it.

Then i add it to my RadDock like this:

private void Add_RadForm_asDocument_ToRadDock(RadDock rd, HostWindow hw, object radform, string title)
{
    bool found = false;

    foreach (var item in radDock_main_notr.DockWindows)
    {
        if (item.GetType() == typeof(HostWindow))
        {
            if (((HostWindow)item).Name == radform.GetType().Name + "1")
            {
                found = true;
                hw = (HostWindow)item;
            }
        }
    }

    if (found == false && radform != null)
    {
        if (hw == null || hw.Text == "")
        {
            hw = rd.DockControl((System.Windows.Forms.Control)radform, DockPosition.Fill, DockType.Document);
        }
    }

    hw.Text = title;
    hw.CloseAction = DockWindowCloseAction.Close;
    hw.ToolCaptionButtons = ToolStripCaptionButtons.None;
    hw.Select();
}

The RadFrom is added to the RadDock:

Settings is the new RadFrom thats now docked.
But when i try to use the RadDropDownList then its "stucks" (also the other GUI controls):

The  changed selection of the RadDropDownList will not change.
When i close the RadForm via the "x" and eropen it again it works.

When setting the theme to a "touch/material" theme the padding & RadRibbonBar size increases.

When switching to a theme that isn't this type the spacing remains.

Non "touch/material" theme originally

Switch to "touch/material" theme

Switching back to a non "touch/material" theme

When testing this in the Telerik Theme Viewer when switching from a "touch/material" theme to a non "touch/material" type a message box instructing application restart is required is returned.

Zooming in will throw an Exception that crashes the program.

The ZoomLevel needed to cause the exception is dependent on the area of the RadMap selected.

Provider: BingRestMapProvider

ImagerySet AerialWithLabelsOnDemand

Zooming in over Antarctica, Exception thrown zooming in at MapElement.ZoomLevel 14.

Zooming in over Australia, Exception thrown zooming in at MapElement.ZoomLevel 21.

I can't provide a project or even code snippets that would make sense out of context because the code base is too complex for an easy replication to be setup.

We are trying various things like calling Refresh, Update.

Hoping this is something you've encountered before and have some suggestions.

1. Select the ColorBox's ellipses to open the Color Dialog

2. Select the Web tab

3. Select Any colour in this Page

4. Select Transparent

Colour will update

5. Select the Professional tab

6. Select any colour

Colour won't update

7. Select any colour

Colour won't update

8. Select OK on Dialog

Colour will be transparent

Values will be same as selected in step 7

I just upgraded to the latest version of Telerik products and facing the issues described below.

When dragging and drop Telerik UI objects from the toolbar on a form, the dialog box below is displayed with question but there is no button to click to answer the question and I don't where to stop it.

See screenshot attached.

I have made an override for class GridViewDataRowInfo (called GridViewDataRowInfoPlus)

Every time a new row is created by RadGridView, I expect OnCreateRowInfo to be called, so I can return my own instance of GridViewDataRowInfoPlus.

This goes well until a user enters new data in a new row and when this row is added the grid, OnCreateRowInfo is not being called and an instance of GridViewDataRowInfo is added to the grid.

For me that is unexpected and undesirable. Maybe I am doing it wrong. In that case: What is the correct way to intercept the row-creation-process and return instances of my own type?

Repro steps:

1. Make a datatable with a string-column with a max. length of 10 characters.
2. Add a row with a string of max. 10 characters.
3. Bind it to a RadGridView
4. Add an event-handler to DataError which will cancel the action if a data error occurs.
5. In the UI, enter data into the cell. Make it longer than 10 characters.

Expected behavior:

1. The same behavior as CellValidating.
2. De user stays inside the editor so it can modify the text.

Observed behavior:

1. The editor is closed, the new text is not displayed.

Report steps:

1. Make a datatable with a string-column with a max. length of 10 characters.
2. Will the datatable with some data.
3. Bind it to a RadGridView
4. In Excel (or another applicatie) create a now table with some strings, this time longer that 10 characters.
5. Paste this data from Excel to the RadGridView

Expected behavior:

1. The strings that are to long will either cause an exception or they are truncated.

Observed behavior:

1. The string with the value that is to long is skipped during pasting.

Extra detail:

In the method MasterGridViewTemplate.PasteDataToRow the next piece is code is located:

if (CurrentView.ViewTemplate.Columns[columnIndex].DataType == typeof(string))
{
    if (column is GridViewTextBoxColumn viewTextBoxColumn && viewTextBoxColumn.MaxLength > 0 && rowData[rowIndex].Length > viewTextBoxColumn.MaxLength)
        obj = rowData[rowIndex].Substring(0, viewTextBoxColumn.MaxLength);
}

When I create a new form-class, which derives from RadFrom, and I override the method OnLoad, then OnLoad is called during construction. This should never happen!

As Microsoft states: "The OnLoad method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class."

See: https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.form.onload?view=windowsdesktop-6.0 

The OnLoad method can be used to load controls with data. But these controls are not even initialized, because the method InitializeComponent has not been called yet.

Hi,

An HTTP Request returns me an error in HTML format. Please see img001. This image was capture in debug mode in Visual Studio.

When I want to show a MessageBox or a Label with this HTML, appears like in img002.

Thank you!

The HTML text is:

• I'm using Visual Studio 2022 Community. Running as Admin.
• I've installed the latest Winforms (Telerik_UI_For_WinForms_2022_1_222_Dev.msi)
• I open Visual Studio and select to create a Word-like project.
• The files are all created
• One nuget reference is present under Dependencies/Packages, but shows as unresolved (UI.for.WinForms.AllControls.Net60 (2022.1.222.0))
• Using the NuGet Package Manager, there is no Telerik package source present.

So, at this point this seems to be a possible bug. The template project did not setup correctly. I have literally done nothing other than download and install Telerik WinForms today and then try to create this project. This _should_ work or give me instructions of further setup that I have to do manually.

I did try a couple other things, but also failed to get things working.

• I tried to setup the Telerik Package Source as https://nuget.telerik.com/v3/index.json
• I was able to see various WinForms packages in the Package Manager, includes the one registered in the project. But VS won't update the project to resolve the package.
  
• I uninstalled the nuget package to try reinstalling it, but the re-install failed with the following messages

Dear Telerik Team!

Even though your components are one of my favourite 3rd party tools that I use in software development for years now; I have to rise a bug ticket for component called "TelerikMultiSelect". The problem is that when the autocomplete box's data source is updated for the first time using a timer's event the autocomplete box remains empty and I have to click outside and the inside of the input again.

Please consider investigating and fixing this issue.

Kind Regards,

Balázs Koncz
