Hey at Telerik

I have found a bug in the RadDateTimePicker.
When the control is continuously enabled/disabled the Text element of the control stops showing the date.

I need this functionality to rebind a RadDateTimePicker to a SelectionChanged event on a RadGrid.

I have reproduced the bug in a little test project (Of cource without references). http://kort2.lifa.dk/examples/RadDateTimePickerMissingDateText.rar

Try and disable/enable the RadDateTimePicker numerous times, after fourth click the Text control element of the RadDateTimePicker stops working.

Sincerly Jan.

Hi Jan,

Thank you for writing and for the provided project.

I can confirm the described behavior and would like to suggest using DateTimePickerElement's Enabled property, for example:

this.radDateTimePicker1.DateTimePickerElement.Enabled = false;

Please refer to the modified project. I have updated your Telerik points for bringing this issue to our attention.

Let me know if you have any additional questions.

Hey Peter
The problem still exists, i'm using version latest dev version 2011.2.11.831,
i can see you have referenced a much older version 2010.3.10.1215.

Am i supposed to revert back to this version?

This would have a big impact om the rest of project!

Hey Peter.

I have lookied at the modified example you sent back.
Apparently you also changed the reference to the DateTime object reference from this.datetime to DateTime.Now.
It works if DateTime.Now is reference but fails if another DateTime is referenced.

I need to reference a specific date and not DateTime.Now.

The problem must be that the text element doesn't refresh onless the date is changed.

Hi Jan,

Thank you for writing back.

I can confirm that the scenario works properly only with DateTime.Now. As a workaround, please set value to DateTimePickerElement.TextBoxElement:

this.on = this.radDateTimePicker1.DateTimePickerElement.Enabled = true;
this.radDateTimePicker1.DateTimePickerElement.TextBoxElement.Value = this.dateTime;            
this.radButton1.Text = "Turn off";

In my project I referenced our latest assemblies (2011.2 11.831). However, if you do not have these assemblies at the same location I have them on my PC and at the same time you have 2010.3.10.1215 installed, Visual Studio may change the references taking the assemblies from your GAC. I hope this clarifies the case.

Please find the modified project.

I hope this helps.

Best wishes,
Peter
