WPF RadDatePicker - Calendar disappears on selecting next/previous month

[Ashish]

Hi,

I am using RadDateTimePicker control for my WPF app.

On clicking the calendar icon next to the data text box, the calendar shows up and I can select a date.
But when I hit next/previous to change month, the Calendar disappears and even after hitting the little calendar icon, the calendar doesn't show up ever again.

Here's the code that is being used on my WPF screen:

<telerik:RadDateTimePicker x:Name="editableStartDate" Width="100" Margin="0,1" IsTooltipEnabled="False" InputMode="DatePicker" SelectedValue="{Binding StartDate, Mode=TwoWay}" HorizontalAlignment="Left" VerticalAlignment="Top" Height="26" Grid.Row="2" Grid.Column="1" />

Am I doing something wrong here ? Please let me know.

thx,
Ashish

Any thoughts?

Hello Ashish,

Unfortunately we could not reproduce such behavior even with your code snippet. The problem most likely lies in your application outside the definition of DatePicker in XAML.

Please, send us a sample project illustrating the issue. If we can reproduce it, we will investigate what is causing it.

Kind regards,
Dani

Thank you Dani,

Here is the complete code:

                <Grid >

                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="0.20*"/>
                    <ColumnDefinition Width="0.80*" />
                </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="0.14*" />
                    </Grid.RowDefinitions>

                    <TextBlock Text="Start Date: " VerticalAlignment="Center" Margin="0,0,4.726,0" d:LayoutOverrides="Width" />
                    <telerik:RadDateTimePicker x:Name="editableStartDate" Width="100" Margin="0,1" IsTooltipEnabled="False" InputMode="DatePicker" SelectedValue="{Binding StartDate, Mode=TwoWay}" HorizontalAlignment="Left" VerticalAlignment="Top" Height="26" Grid.Column="1" />
                </Grid>

I am using trial version of Telerik WPF Rad controls and .NET 3.5

Please let me know your findings.

Thanks,
Ashish

Hello Ashish,

Thank you for the code snippet, but I'm afraid it is rather insufficient for us to investigate the issue. It contains only a single Grid which is not relevant to the problem. Could you send us a running project ?

All the best,

Hi,

I'm using RadDatePicker and facing same kind of problem during choosing year or month from the calander and then touching year or month it disappears calander rather than giving me option to choose date on tablet using touch. But when I select any date it's fine.

Looking forward of seeking your assistance regarding the issue.

Thanks,

Hassan

Hello Hassan,

We tried to reproduce the behavior but we did not manage. 

Please, let us know the version of the controls you are using in your application. 
Also, it would of a great help if you can send us a sample project where the issue can be observed in order to investigate the case.

Hi Alek,

I'm using version: 2013.2.724.45

Did you try with finger gesture rather than using any mose or ditizer pen. This is happens to me when use touch only and it happens during touching ant year or month from the calender but if I touch on any date it's fine.

Hi Hassan,

We did not manage to reproduce the behavior using the dll versions you've posted in the forum thread. In the same versions we have had an issue with RadDatePicker and RadDateTimePicker which is matching with the case you're describing. The issue is fixed and it cannot be reproduced in the latest versions. Could you please download the latest official release and let us know do you still experience the same behavior?

Hi Alek,

I'm not sure I could able to make you understand about the issue. Anyway, it's not previous or next month button. This is happened - on win 7 tablet using touch only - when you touch any month from calander say March - 2014 and then if you touch 2014, now if you touch on any month say Mar or Apr etc rather than keeping the calander open it closes the calander once you select month and this is the issue. What I want untill I touch any date it will not close the calander.

Hassan

Hello Hassan,

In the attached file you can find two videos. In the first one you can see the issue reproduced using the dll versions from your forum post. The second one is under the latest official release. The actions are the same, but the issue is fixed and you are able to reach the day view.
