How do I make a cell or cell ranges read-only ?

I want to show the user the cells values, but don't want them to be able to edit the data.

Thanks

Reading this document: https://docs.telerik.com/devtools/winforms/controls/syntax-editor/features/word-wrap

States that wordwrap should now be a thing.  However, it isn't for me.

I've updated to the latest Telerik (already was), and no luck.

Basically what the title says.  I've selected part of a document, and I want to replace only part of the text, within that selection.  Is this possible?  I've been trying various things, but so far, no luck.

In short, I've added commenting to my text.  That works fine, but I can't uncomment (remove the comment characters) from the selected text.

In the image below I have five DocumentWindow (state names) and a ToolWindow (Properties). Following this steps, the ActiveWindowChanged event is called twice from different windows:

1. make Colorado (tabbed window) the active window
2. make California (Floating window) the active window
3. make Properties (ToolWindow) the active window. At this point, the ActiveWindowChanged event is called twice. The first one changes the ActiveWindow from California to Colorado. And the second call changes the ActiveWindow from Colorado to Propeties.

This is making the application shows the Colorado properties instead of the California properties.

Is this the expected behavior? Is there a way to fix it?

I am using UI.for.WinForms.AllControls.Net40 v2022.3.921

Is there an event like this in the Spreadsheet control?

What I need is when the user selects a single column, I enable/disable various menu options, but I can't find an event which is fired when a column in a sheet gets selected.

(BTW - I got the name of this event from ChatGPT, which thinks that a RadSpreadsheet has this event, but it's working from data up to 2021, so maybe this is an old event?)

Thanks

I need to show the user some XML, but formatted nicely (identing, colors etc).

Can I use RichTextEditor for this? If so how (vb.net please!).

I don't need to edit the XML now, but I will need to in future (hence not using a Browser-type control)

Thanks

I have a project where the user wants a multi tab control on a WinForm - no problem.

On the first tab however, they want too many controls to fit on the screen, Therefore they want the first tab's RadPageViewPage to scroll up and down. They do not want a sub tab. The problem is that there are so many controls that if they were separate tab they would fill four of them. I realize that scrolling is not the point of a tab control but this is what they want. Still, there are limits to the size of a Form and the size of the RadPageViewPage control.

Is this something that can realistically be done or is this just asking for too much?

Thanks

Hi,

I'm trying to display the check box in the header of a GridViewCheckBoxColumn and have it centered but it is still not aligned with the rest of the rows. 

I set the column property HeaderCheckBoxAlignment = ContentAlignment.MiddleCenter but still there is a gap. Please see the image attached.

Thank you,

Hi Telerik support team,

I've performance issues with sorting in a radGridView. Below you find a very simple example (grid with 2 text columns) and nothing specials. The dataset (deserialized from a json file) contains 7560 rows, which is not much. 

My own conclusion is 'it depends on the data'. In my dataset the column PhaseName is sorting ok. ProjectName is very slow. When I group the columns I see that ProjectName has not much groups (so a lot of duplicates) and PhaseName has a lot of groups (so, not much duplicates).

I tried to fasten it up with custom sorting but I got the same result. Can you help me with this issue??

(by the way: grouping also takes a lot of time)

Code:

    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();

            radGridView1.Columns.Add(new GridViewTextBoxColumn("ProjectName") { ReadOnly = true });
            radGridView1.Columns.Add(new GridViewTextBoxColumn("PhaseName") { ReadOnly = true });

            LoadData();
        }

        private void LoadData()
        {
            var json = File.ReadAllText(@"c:\Daniel\content.json");

            var list = JsonConvert.DeserializeObject<List<ProdTemp>>(json);
            radGridView1.DataSource = list;
        }

        internal class ProdTemp
        {
            public string ProjectName { get; set; }
            public string PhaseName { get; set; }
        }
    }
