[Solved] Restrict access to the textbox in DateTimePicker

Hi,
I want to restrict access, or be able to remove the edit function to the Textbox in the DateTimePicker.
I tried to hook into the TextChanging Event of th radDateTimePicker1.DateTimePickerElement.TextBoxElement and set the e.cancel = true. No visible changes was made when trying to edit the text, but it seems like it set some date in behind anyway.

I could do Enabled = false on the TextBoxElement, but then the control seems locked and I want the user to be able to push the dropdown button and select the date from the calendar.

Is there any good way to restrict this access?

Regards

i have the following two questions:

Is there an option to disable the "snap to grid" behaviour for appointments to show it at the real y-position.
In the attachement you see an sample of a snapped appointment.
How can I cutomize the appearance of an appointment in the view
For example showing only the begin time, showing an additional picture or text.

Best regards

Scroll bar when expanding hierarchical grid

I have a nested grid with about 300 rows; when I expand this grid from its parent, the vertical scroll bar expands to take up almost the full height of the window, and as I scroll down, the scroll bar becomes incrementally smaller. This make it very time-consuming to scroll all the way down to the bottom, as it has to be done in multiple steps. However, if the number of rows in the nested grid is < 200, the scroll bar is of normal size, and scrolling is easy and quick.

Is there any way to remedy the behavior for larger nested grids?

[Solved] Text with carriage return

Hi,

One of the grids in our application displays a field which can contain carriage returns (\r\n). For the grid the multiline and wrap properties are set to false and the ellipse property is set to true, since we want the text to be single line and ellipsed.

However the colum does take the carriage return into account and tries to squeeze the both lines into one line (see screenshot). Each line individually is however ellipsed.

What is the best approach to prevent the column to ignore the carriage returns, in order to have one single ellipsed line? Off course without removing the carriage return from the string itself.

Many Thanks,
Maarten
