When exporting a RadFixedDocument, which contains a signature added with PdfProcessing a NotSupportedException is thrown: 'Stream does not support reading.'

Resolution: When exporting a digitally signed document a stream that allows both reading and writing should be passed to the PdfFormatProvider.

Example:

Stream outputStream = new FileStream("path", FileMode.OpenOrCreate, FileAccess.ReadWrite)

The extension (which also keeps load times high) is prompting me about an expired subscription. We had a 2 seat and a 1 seat subscription. We now only need 2 seats and let the 1 seat expire. But I'm using the 2 seat active subscription. So stop bugging me about the expired 1 seat please :)

Here is how it looks in AdobeReader


Thanks in advance,

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?

The version of Telerik products is requested as information where submitting a support ticket. In case one forgot the version currently installed, there is no way to find it (may be I am the only one who don't know). Usually most software provide such information in the "About" box. I found it difficult and not very useful that the "About" menu of Telerik connect to the Progress Home Page instead of displaying some useful information about the current installation (user name, version, installed components, license status, etc....). There are already many other actions (request support, online documentation, etc...) that connect to the web site. The "About" box should just be displayed within VS and provide information on the installation. Or at least you link it to the Progress Control Panel and adding a page for information I mentioned and more that user may need to know when needed.

Below is an example from VS.

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);
}
The property viewTextBoxColumn.MaxLength returns 32767 (and not 10) which is clearly a related and possibly a separate bug.

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.

  • 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

Restoring packages for C:\DevGit\pws\pws.core\pws.core\pws.core.csproj...

The following code to make the headers bold in a RadGridView.  After upgrading to different 2022 versions from 2021, this code causes a Parameter is not valid error in ((System.ComponentModel.ISupportInitialize)(this.RadGridView1.MasterTemplate)).EndInit();

If I comment out the code and run then there is no error generated.

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)

{
    if (e.CellElement is GridHeaderCellElement)
    {
        e.CellElement.Font = myCustomFont;
    }

Eery time I use the GridView, I have to remember to un-select the last item in the list.

This is almost always to wrong thing to be selected - so why select it by default?

..and the way to swith this 'feaure' off isn't obvious - I always have to look it up....RadGridView1.CurrentRow = Nothing

Hi. it was great to see the option "ImageOnly", for columns of small width, where only the image is placed in the header, and the "HederText" property was set, for the correct display of the grouping field

GridViewDataColumn column;

column.HeaderText = "Счет";

column.HeaderImage = ...; // some img

column.TextImageRelation = TextImageRelation.Overlay;



GridViewDataColumn column;

column.HeaderText = "";

column.HeaderImage = ...; // some img

column.TextImageRelation = TextImageRelation.Overlay;

it’s impossible to choose one thing, either an ugly header, or a grouping without a description

How to reproduce: check the attached project:

Workaround: when the form is opened in the designer make sure that all pages are made visible at least ones so the controls are initialized, before attempting to access collection editors via properties window

This behavior occurs when there is no Telerik package installed in the project but the toolbox loads the controls using the version available in C:\Program Files (x86)\Progress\ToolboxNuGetPackages.

Then drag a gauge form the toolbox and drop it into the form:

To reproduce:

 

        public RadForm1()
        {
            InitializeComponent();

            string txt = "what follows is test characters (some of) which should cause error:  เปลี่ยน UPS ที่ห้อง Truck scale เนื่องจากเมื่อวันพฤหัสที่ 13 มีการออฟเบรกเกอร์ที่ ฺฺB/H แต่ว่า เครื่องคอมพิวเตอร์ที่ T/S ดับ ตัว UPS ไม่ทำงาน ทำให้ข้อมูลขณะนั้นหายไป   ";
            this.label1.Text = txt; // No error

            Font font = this.label1.Font;// new Font("Segoe UI", 9.5f, FontStyle.Regular);
            this.radLabel1.Font = font;
            this.radLabel1.Text = txt; //GDI error
        }

Workaround: 

this.radLabel1.UseCompatibleTextRendering = false;

        {



            label1.Text = radCalendar1.SelectedDate.ToString();

        }
