Hello,

I'd like to localize the RichTextEditorRibbonBar. I've found an useful link with a sample xml file which helped me to localize some parts. But it seems it doesn't contain all the controls of the RichTextEditorRibbonBar. For example - I wasn't able to localize the Simplified Layout:

There is no occurrence of a word Simplified in the xml file.

How should I localize this?

Thanks

Tomáš

I want to prompt the user some messages if the values of PropertiGrid changed  when they close the RadForm. 

 

How do I do that? Thanks!

Hello All,

I  have converted my Winforms C# Application to Telerik using the Telerik conversion extension tool in VS 2017 . It is converted but I see the events are not associated with the control even though the code exists in the code behind file.

Is this a known issue?  Any suggestion or help is really appreciated.

Example: A Raddropdown list selected index change event is not tied to the Raddropdown. I see the event in the code behind.

I have a Listview with CustomVisualItem formatting in IconView.  When the directional keys are tapped or an item is clicked, the SelectItemChanged event is triggered but the selection highlight does not follow.  Since CustomVisualItems are used, do I need to break out the crayons in VisualItemFormatting?

The form contains a RadListView and a RadLabel to display a result.

Thanks!

public RadForm1() { InitializeComponent();

this.radListView1.EnableKineticScrolling = true; this.radListView1.KeyboardSearchEnabled = true; this.radListView1.ViewType = Telerik.WinControls.UI.ListViewType.IconsView; this.radListView1.SelectedItemChanged += new System.EventHandler(this.radListView_SelectedItemChanged); this.radListView1.VisualItemCreating += new Telerik.WinControls.UI.ListViewVisualItemCreatingEventHandler(this.radListView1_VisualItemCreating); this.radListView1.DataSource = JunkData(); } private void radListView1_VisualItemCreating(object sender, Telerik.WinControls.UI.ListViewVisualItemCreatingEventArgs e) { e.VisualItem = new CustomIconVisualItem(); } private void radListView_SelectedItemChanged(object sender, EventArgs e) { RadListViewElement element = sender as RadListViewElement; ListViewDataItem item = element.SelectedItem; if (item == null) return; DataRowView dataRow = (DataRowView)item.DataBoundItem; if (dataRow == null) return; DataRow row = dataRow.Row; radLabel1.Text = row["Title"].ToString(); } private DataTable JunkData() { DataTable dt = new DataTable(); dt.Columns.Add("Title", typeof(string)); dt.Rows.Add("T1"); dt.Rows.Add("T2"); dt.Rows.Add("T3"); return dt; }



class CustomIconVisualItem : IconListViewVisualItem
{
        private LightVisualElement titleElement;
        private StackLayoutPanel stackLayout;

        protected override void CreateChildElements()
        {
            base.CreateChildElements();
            stackLayout = new StackLayoutPanel();
            stackLayout.Orientation = System.Windows.Forms.Orientation.Vertical;
            stackLayout.AutoSize = true;
            titleElement = new LightVisualElement();
            titleElement.NotifyParentOnMouseInput = true;
            stackLayout.Children.Add(titleElement);
            this.Children.Add(stackLayout);
        }

        protected override void SynchronizeProperties()
        {
            this.titleElement.Text = this.Data["Title"].ToString();
        }

        protected override Type ThemeEffectiveType
        {
            get
            {
                return typeof(SimpleListViewVisualItem);
            }
        }
}

It seems that after the Validation Provider kicks in on a control - and sets focus to it and displays the 'error' message....

That it keeps the focus on that control and the user cannot click on a different control on the form.

So, for example.

Let's say there are 2 radio buttons - each radio button causes a dropdown to load certain records

The user clicks on the Dropdown - then realizes they needed to click on the 2nd radio button first.

But now, the validation provider won't let them click the 2nd radio button because it maintains focus on the dropdown.

Is there a way to 'release' the focus so that the user can click on the 2nd radio button?

Hi.

Using control version 2021.2.614.2
VS2019 16.8.3
Windows10

I'm using RadCheckedDropDownList and I get an exception when I click on the text entry and press the BackSpace key.
This also seems to occur in the Demo Application Telerik UI for WinForms R2 2021. 

I tried to disable the BackSpace key, but it didn't work. 
Is there a solution?

I have a form with two TextBox controls with ShowEmbeddedLabel and RepositionEmbeddedLabel enabled. The TextBox font size is 18P and the Embedded Label sizes are 18P and 10P. 

When running, the first textbox with the larger EL looks and works fine.  The textbox with the 10P EL, not so much.  The EL rests in the center of the control, rather than the bottom.  What property have I overlooked to have the 10P EL  align to the bottom of the control rather than hover in the center?

I've tried disabling TextBoxElement.AutoSize and setting its Size, but that really confuses the renderer. Messing the the LightVisualElements, didn't help either. Resizing the control almost works, but the descenders, the 'tails', of letters are clipped then the EL is bottom aligned.

 

Thanks!
        public RadForm1()
        {
            InitializeComponent();

            radTextBox1 = new Telerik.WinControls.UI.RadTextBox();
            radTextBox1.Font = new System.Drawing.Font("Segoe UI", 18F);
            radTextBox1.Location = new System.Drawing.Point(10, 10);
            radTextBox1.Size = new System.Drawing.Size(300, 80);
            radTextBox1.EmbeddedLabelText = "RTB1: 18F x 18F";
            radTextBox1.ShowEmbeddedLabel = true;
            this.Controls.Add(this.radTextBox1);
            radTextBox1.TextBoxElement.Font = new System.Drawing.Font("Segoe UI", 18F);
 


            radTextBox2 = new Telerik.WinControls.UI.RadTextBox();
            radTextBox2.Font = new System.Drawing.Font("Segoe UI", 18F);
            radTextBox2.Location = new System.Drawing.Point(10, 90);
            radTextBox2.Size = new System.Drawing.Size(300, 80);
            radTextBox2.EmbeddedLabelText = "RTB2: 18F x 10F";
            radTextBox2.ShowEmbeddedLabel = true;
            this.Controls.Add(this.radTextBox2);
            radTextBox2.TextBoxElement.Font = new System.Drawing.Font("Segoe UI", 10F);
        }

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);
}
