Only users that have Telerik installation version 2021.1.122 are affected.

Symptoms:

Clients that have Telerik installation version 2021.1.122 can not build successfully .NET Core/.NET 5.0 projects. The following error occurs while compiling the project:

The problem is a missing NuGet fallback folder.

Solution:

You should create the missing ToolboxNuGetPackages folder in the installation folder of the controls, usually at C:\Program Files (x86)\Progress\ToolboxNuGetPackages.

I have a rad data entry in a form that when I change the data through it's bindings it doesn't clear all the fields.  Usually check boxes and dates or dropdowns leave their current selected value if the new data set has null values.

!. is there a way to fix that?

2. If not how can I loop through all the controls in the rad data entry to clear all the controls?

Below only shows 4 controls instead of the many that textboxes, etc.  *Rde is the name of the rad data entry item

foreach (Control c in Rde.Controls)
{
MessageBox.Show(c.Name);
}

Good afternoon!

 

I have a class object that has several properties. I have a RadGridView that I've created columns in with field names that match the class properties. When I assign the list of class objects as the datasource to the gridview, everything fills in correctly except the list of strings.  Everything shows up great except the combo boxes that have field names that corresponds with List<string> properties in the class object. The list of strings displays as "System.Collections.Generic.List". Each row is a distinct object with a different list of strings. How do i populate the combo boxes in the with the data in the class object's properties that are List<string>?

Dear Telerik Team,

We have a scaling problem on a 4K monitor when using RadPivotGrid and calling the RunExport method over the PivotGridSpreadExport instance.

We created the small solution in Visual Studio 2019 which is enough to successfully recreate the issue. Please note that during the development of the solution, the automatic scaling option in Visual Studio was off.

After starting the solution on a 4K monitor and calling the RunExport method over the PivotGridSpreadExport instance, the scaling was automatically performed over the whole solution (all forms and all their components were scaled, see the attached screenshots). At the moment of starting the solution, Scale and Layout option (under Display Settings on Windows) was set to 150% (Recommended). The same invalid result was when we set that option to 175%. Also, we tried to start the solution with every possible value for the AutoScaleMode property (Font, Dpi, None, Inherit) for all existing forms in the solution. The result was the same every time.
We think that the RunExport method makes a problem - the scaling is valid when we skip that call (see the attached screenshots), under the same conditions.

The mentioned solution with the required files can be found on the following link:

https://webshare.bexelconsulting.com/public/bexel/607-jenwspc47/Telerik%20-%20PivotGridSpreadExport.RunExport%20-%20Scaling%20Problem.zip

Could you please take a look at the solution and investigate the described issue?

Should you have any further questions about the described issue, feel free to contact us.

Thank you in advance for your help.

Is there a way to set the DescriptionImage Image Alignment to TopLeft?

If not, then the TaskCardElement.DescriptionImage.ImageAlignment property is Missing

I am using the simple code below to load and image from SQL, then save it back to the Image datatype column.

I am able to load the image, but when I perform ANY edit feature (from the RadImageEditor control) the size of the image (relative size on disk in bytes) increases over 10x the original image.  Eventually it will consume all the memory and crash the application.  This behavior does not happen if I load a fixed image directly from disk.

The two attached images show the size of the image after immediately loading it, then the size of the image after performing a single Rotate 90 degrees.  

I cannot find any example of either loading an image from a DB nor saving to DB. Please review and provide any correction to loading and saving images (blob, image)  from SQL, or please provide a simple example of loading and saving a SQL image.

FYI: objAttach.ImageBlob is defined as Byte()

    Private Sub frmAttachmentViewer_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Me.lblMessage.Text = ""
        mbImageChanged = False
        Dim ms As MemoryStream = New MemoryStream(objAttach.ImageBlob, 0, objAttach.ImageBlob.Length)
        Dim img As Image = Image.FromStream(ms)
        Me.RadImageEditor1.OpenImage(img)
        lblImgSize.Text = "Size: " & ms.Length & " KB"
    End Sub

    Private Sub RadImageEditor1_CurrentImageChanged(sender As Object, e As ImageChangedEventArgs) Handles RadImageEditor1.CurrentImageChanged
        Dim ms As New MemoryStream()
        Me.RadImageEditor1.SaveImage(ms)
        lblImgSize.Text = "Size: " & ms.Length & " KB"
    End Sub

    Private Sub cmdSave_Click(sender As Object, e As EventArgs) Handles cmdSave.Click
        Dim ms As New MemoryStream()
        Try

            Me.RadImageEditor1.SaveImage(ms)

            Dim iToInt As Integer = Convert.ToInt32(ms.Length)
            Dim imgBinaryData As Byte() = New Byte(iToInt - 1) {}
            imgBinaryData = ms.ToArray()
            objAttach.ImageBlob = imgBinaryData

            objAttach.save()
            Me.lblMessage.Text = "Image Saved"
        Catch ex As Exception
            MessageBox.Show("Error Saving Image: " & vbCrLf & vbCrLf & ex.Message)
        Finally
            ms = Nothing
        End Try
    End Sub

Hello,

1. In the attached picture, the localization strings of the items with the red arrow are not in the LocalizationProvider. How can I localize them?
2. How can I turn off the DropDown button shown with the blue arrow in the picture?

Kind regards.
