Hello,

I am using syncfusion Schedular control in my project. I am facing some issues in this.
below is my code

<Schedule:SfSchedule x:Name="Schedule1" ScheduleType="Week" Resource="{Binding ElementName=Resource_Combo,Path=SelectedItem, Mode=TwoWay}" ScheduleResourceTypeCollection="{Binding ResourceCollection}" DayHeaderOrder="OrderByDate" Grid.Column="2" HorizontalAlignment="Left" Grid.Row="1"  VerticalAlignment="Top" Height="454" Grid.RowSpan="8" Width="1300" Margin="0,86,0,0"/>
               <ComboBox x:Name="Resource_Combo" Height="45" Width="265" Background="Black" SelectedIndex="0" Margin="15" Foreground="White" IsEnabled="False" HorizontalAlignment="Left">
                            <x:String>AppointmentSchedular</x:String>
                        </ComboBox>

in this code i got an exception
"object reference not set to null"

Hello

Is there any way to bind combobox at runtime from code behind with Schedule.

I don't want to bind this in xaml (Resource="{Binding ElementName=Resource_Combo,Path=SelectedItem, Mode=TwoWay}")

thanks

[Joy Oyiess Rex K]

Hi Muhammad,

 

Yes, we are able to bind the ‘Resource’ property of SfSchedule with the SelectedItem property of ComboBox, for that please refer the below code snippet.

 

Code Snippet:

          

[c#]

            Binding resourceBind = new Binding();

            resourceBind.Source = Resource_Combo;

            resourceBind.Path = new PropertyPath("SelectedItem");

            resourceBind.Mode = BindingMode.TwoWay;

            BindingOperations.SetBinding(this.Schedule1, SfSchedule.ResourceProperty, resourceBind);

 

 

We have also modified the sample for the same, please find the sample in the attachment.

 

Please let us know, if you need any further assistance.
