Hello 

I am trying to fix some text when it is being inserted in a richtexteditor but each time I move the caret position to document end the font changes back to default. This is my code:

 if (txtCorrections.Text[txtCorrections.Text.Length - 1] == ')' && txtCorrections.Text[txtCorrections.Text.Length - 2] == ' ')
                {

                    txtCorrections.Text = txtCorrections.Text.Remove(txtCorrections.Text.Length - 2, 1);
                    txtCorrections.Document.CaretPosition.MoveToDocumentEnd();


                }
                I use this code in a textChanged.

Thank you for help.

Hello,

We are using radGridView in a winforms application. The last 4 columns visible in the screen shot have the property "IsVisible" set to false. When opening the window for the first time ,the list is empty and we are launching some synchronisation processes in the background to charge the information to display. However, the 4 last columns show up in the list and are filled with information as soon as the synchronization has finished. When closing and reopening the window, the columns disappear and everything is correct. What could be the reason for them to show up even though their visibility is set to false?

.NET version: 6
Telerik version: 2024.3.806

Thank you in advance!

Hello,

I am new to WinForms.

Is there a possibility to disable the Arrow for the RadDropDownList ?

When I set the component to readonly, I can still choose a new value via the arrow.

But then the value is never saved because it is read-only.

And wich property do I have to set for this?

I have a question about the RadGridView

I want to retrieve the new value of a cell that I have changed.

When I change a cell from value "AB" to "CD", how can I then get "CD" ?

Should I use the RowsChanged or CellValueChanged event?

In the RowsChanged, you have a property e:NewItems, but I don't know how you then can get value "CD" from e:NewItems.

Hi!

I have MdiParent Form which hosts multiple MdiChids. I would like to determine why the MidParent is being closed withing the MdiChild-ClosingEvent. The CloseReason in the MdiChild-ClosingEvent only says "MdiFormClosing". But I dont know if the MdiParent is closed due to user operation (eg. pressing X in upper right corner) or Windows is being shutdown.

How can I solve that?


background:

The MdiChild_FormClosing-Event either asks if this or all childs shall be closed. If all are confirmed, the static variable of "bool _ForceClosing" prevents the next child from asking again. So good so far. I would like to skip this confirmation stuff in case, windows is being shutdown. But this CloseReason in MdiChild only has UserClosing or MdiFormClosing.

System::Void 
Form_Client::Form_Client_FormClosing(System::Object^  sender, System::Windows::Forms::FormClosingEventArgs^  e)
  {
    //-----------------------------------------------------------------------------------------------------------------------------
    try
    {
      //-- mdi closing already confirmed --------------------------------------------------------------------
      if (this->_ForceClosing == true)
      {
        e->Cancel = false;
        return;
      }
      //-- windows shutdown ---------------------------------------------------------------------------------
      else if (e->CloseReason == System::Windows::Forms::CloseReason::WindowsShutDown)  // not working
      {
        this->_ForceClosing = true;
      }
      //-- user single closing (ask if connected) -----------------------------------------------------------
      else if (e->CloseReason == System::Windows::Forms::CloseReason::UserClosing)
      {
        // ask if this child shall be closed
        if (Result != System::Windows::Forms::DialogResult::OK)
        {
          e->Cancel = true;
          return;
        }
      }
      //-- mdi parent closing initiated ---------------------------------------------------------------------
      else if (e->CloseReason == System::Windows::Forms::CloseReason::MdiFormClosing)
      {
        // ask if all childs shall be closed
        if (Result != System::Windows::Forms::DialogResult::Yes)
        {
          e->Cancel = true;
          return;
        }
        //-------------------------------------------------------------------------------
        this->_ForceClosing = true;
      }
      //-- unknown reason -> just close all -----------------------------------------------------------------
      else
      {
        this->_ForceClosing = true;
      }
    }
    //----------------------------------------------------------------------------------------------------------------------------
    catch (System::Exception^ ex)
    {
      System::Windows::Forms::MessageBox::Show( ex->ToString() ); 
    }
  }
Thanks in advance

Hello, can you please tell me how to properly localize radtreeview nodes text? The localization is working properly for other controls like rad menu items: In case of them, I only had to change the language property in parent RadForm, and set text property in particular language for that control and it worked fine. However, it cannot be done for tree nodes. For tree nodes I tried changing the language property in the parent form then opening the property builder where I set Text property. It turns out that the text set in this property is the text that is shown in all languages, not just in the one selected in the main form. So, how to do this?

Hi Telerik support team,

I’ve a question about the GridView for Winforms. In my grid I’ve a combobox column which is based on a enum. Before, in net framework 4.7.2 I had a nice wrapper around it in order to translate the values. Works like a charm.

Now we’ve updated our application to net8 and that part does not work anymore. I’ve isolated the code in a simple example program. The attached solution contains 2 projects, one is net framework and the other is net8. Code is the same. In the net8 I get an exception when I try to set a filter on the column.

Are you aware of this? Did I miss something? How can I get this working in net8?

Any help is welcome.

Regards,

Daniel Kaya

as per the title I group records by groupID, but the records also contain dates, I in turn would like to order the groups by "creation date" without creating other subgroups, leaving the grouping by groupID unchanged.

Currently I use this code for grouping:

GroupDescriptor descriptor = new();
descriptor.GroupNames.Add("GroupID", ListSortDirection.Descending);
this.DGNotes.GroupDescriptors.Add(descriptor);
I tried using examples in the documentation but to no avail. Thanks for your help.

Merci de vos retours.
