I want to prevent the radDateTimePicker from getting focus with TabStop set to FALSE and the control is enabled. I can do this with TextBoxes and CheckBox, etc, but this control, no matter what I do, even if I set the internal controls to TabStop = false, the control still gets focus.  

 

Looking for a solution

TIA

Hello, 

Please have in mind that RadDateTimePicker internally hosts the standard MS TextBox which actually gets the focus. If you want to skip focusing the RadDateTimePicker control, it is necessary to set the TabStop property to false for the hosted textbox:

            this.radDateTimePicker1.DateTimePickerElement.TextBoxElement.TextBoxItem.TabStop = false;

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Sorry, busy work got in the way.  

 

What I don't understand, is why, with all your controls, do we, as developers, have to go through all these steps.  Why are these controls inside a control automatically set based on the main control.  It's really fustrating to have to go through this step for every control.  Yes, I know we can subclass this, but really

So, you are right, I have to put CODE in the code-behind to do this. Using the EDIT UI ELEMENTS, the TextBoxElement is not visible.  Here is what we get, and even setting what I have nighlights, still doesn't work. I am required to, in code, to set as you outlined above.

Hi, Mark,

The provided feedback is greatly appreciated.

I agree with you that it is frustrating to iterate all the controls and set the DateTimePickerElement.TextBoxElement.TextBoxItem.TabStop property to false for the nested MS TextBox. Most of our editors, e.g. RadTextBox, RadDateTimePicker, RadDropDownList, internally use the standard MS TextBox. Even though we have our own RadTextBoxControl, there are still some differences in the internal implementation and the supported features, like right-to-left support:

https://docs.telerik.com/devtools/winforms/controls/editors/textboxcontrol/radtextboxcontrol-vs-radtextbox 

As to the Edit UI Elements option, the RadTextBoxItem.TabStop property is not serialized in the Designer.cs file. That is why after closing the designer and reopening it again,  the value is not stored to the previously set value. As you have already found out, it should be set programmatically as demonstrated in my previous reply.
