enter image description here

I would like it in dd-MM-yyyy.

I tried the following:

set custom format: "dd-MM-yyyy"

But Its not changing.

What could be the problem?

Please help me.

Solution

Ensure that control Format property is properly set to use a custom format:

DateTimePicker1.Format = DateTimePickerFormat.Custom

Then this is how you can set your desired format:

DateTimePicker1.CustomFormat = "dd-MM-yyyy"
