Property Value

Type	Description
IEditSettings	An object that contains editor settings.

Remarks

The TreeList configures editor settings for individual columns based on associated data types. You can customize these settings in markup. The EditSettings property returns customized (if any) settings of the processed editor.

Cast an object, returned by the EditSettings property, to a particular editor’s settings interface when you need editor-specific settings:

void OnCustomizeDataRowEditor(TreeListCustomizeDataRowEditorEventArgs e) {
    if (e.FieldName == "HireDate") {
        var HireDateSettings = e.EditSettings as IDateEditSettings;
        if (e.IsNewRow) {
            // Limits the available hire date for new employees two weeks ahead.
            HireDateSettings.MinDate = @DateTime.Today;
            HireDateSettings.MaxDate = @DateTime.Today.AddDays(14);
        } else {
            // Disables the hire date editing.
            HireDateSettings.Enabled = false;
            HireDateSettings.ShowDropDownButton = false;
        }
    }
}

You can also cast the returned object to the base interface if the editor type is unknown or you need common settings:

void OnCustomizeDataRowEditor(TreeListCustomizeDataRowEditorEventArgs e) {
    // Shows the validation icon for every editor
    if(e.EditSettings is ITextEditSettings settings)
        settings.ShowValidationIcon = true;
}

Refer to the CustomizeDataRowEditor event description for more information and an example.
