Disable input field (force user choose date by click on calendar)

[SweNz]

Hi telerik,

I have 2 raddatepicker which are STARTDATE and ENDDATE. My business logic constraint is START DATE must less or equal to END DATE. Now, I'm using SelectableDateStart and SelectableDateEnd property to validate selected date and it works fine. My problem is this method can't handle if user input Date by key-in.

How to disable "Key-in" function ?

My XAML :

<telerik:RadDatePicker x:Name="startDate" SelectableDateEnd="{Binding ElementName=endDate, Path=SelectedDate }" />

<telerik:RadDatePicker x:Name="endDate" SelectableDateStart="{Binding ElementName=startDate, Path=SelectedDate }" />

Please give me some advice , thank you

Hello Swenz,

The easiest way to achieve this is to open RadDateTimePicker in Blend and customize it. The only thing you will have to change is telerik:RadWatermarkTextBox's isReadOnly property to true. I have attached a sample example to demonstrate you this.

The other way to accomplish your needs is to write validation code on SelectionChanged. If you chose this one you will have to write some code, but it will be more flexible.

Hope this helps.

Best wishes,

Hi Ivo,

Thank you for your response. I tested your sample project and it works.But it's really hard to understand in short time then I changed my old RadDatePicker to RadDateTimePicker  and set IsReadOnly = True .. It doesn't work. It's ok...

I'll try to figure out later :))

Best regards,
