Hello Вадим,

I am not really sure that I quite well understand your question. If you would like to be notified that a value in the grid has changed, you can handle the RadGridView.CellValueChanged event. More information about how changes can be tracked in RadGridview is available here: https://docs.telerik.com/devtools/winforms/gridview/insert-update-delete-records/tracking-changes-in-radgridview.

In case you need further assistance please elaborate on your question and let me know in details what you are trying to accomplish.

Regards,
Hristo

my date is in the grid in the format dd.mm.yyyy.
I want to make it so that the user does not enter the point itself. "".
Just entered the numbers, and the dot itself was put.

Hi,

First, you will need to set the CustomFormat property of the column which controls how the text inside the editor is formatted. Then you can handle the CellEditorInitialized event and set the AutoSelectNextPart property on the DateTime provider: 
public Form1()
{
    InitializeComponent();
     
    //Setup the grid
 
    GridViewDateTimeColumn dateTimeColumn = (GridViewDateTimeColumn)this.radGridView1.Columns["Date"];
    dateTimeColumn.Format = DateTimePickerFormat.Custom;
    dateTimeColumn.FormatString = "{0:dd/MM/yyyy}";
    dateTimeColumn.CustomFormat = "MM.dd.yyyy";
     
    this.radGridView1.CellEditorInitialized += RadGridView1_CellEditorInitialized;
}
 
private void RadGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    RadDateTimeEditor dateTimeEditor = e.ActiveEditor as RadDateTimeEditor;
    if (dateTimeEditor != null)
    {
        this.radGridView1.CellEditorInitialized -= RadGridView1_CellEditorInitialized;
        RadDateTimeEditorElement editorElement = (RadDateTimeEditorElement)dateTimeEditor.EditorElement;
        MaskDateTimeProvider provider = editorElement.TextBoxElement.Provider as MaskDateTimeProvider;
        if (provider != null)
        {
            provider.AutoSelectNextPart = true;
        }
    }
}

I am also attaching a short video showing the result on my end.

Hello,

You can use a different format string, e.g. like this one: 
GridViewDateTimeColumn dateTimeColumn = (GridViewDateTimeColumn)this.radGridView1.Columns[2];
dateTimeColumn.Format = DateTimePickerFormat.Custom;
dateTimeColumn.FormatString = "{0:d/M/yyyy}";
dateTimeColumn.CustomFormat = "d.M.yyyy";

I hope this will help.

You misunderstood me.
Here is the date of 12/03/2018.
I'm starting to edit it.
The first character is selected, i.e. 1 after pressing a key for example 2, the date is changed and goes to the next character 2, when another keys is made, it goes to the next one.
Those. selection and change is one character at a time.
Can so it is more clear?

Hello,

Whether an editable element will be selected or not is determined by the AutoSelectNextPart property of the provider. If you do not want to automatically select other date parts do not set it to true. If you want to have a custom behavior you can create a custom mask provider and substitute the default one in the CellEditorInitialized event. In your custom implementation, you will need to override the SelectNextEditableItem method. It is declared virtual so you should be able to customize it.
