I have a exception when i try to filter the null value for the column, when having Null descriptor and other values as well.  The binding is a dynamic object, i am setting the column type as expected.

I am using the version 2019.2.618.45 of telerik dll

Hi Team,

       We are exporting our appointment details like below (code section) to generate .ics file. When we book an appointment in our WOOFware application, the email confirmation has an attached ICS file to add the appointment to the client's calendar.   The vcaappnt.ics attachment itself is working correctly.  However, if the client uses gmail, there is a banner at the top that allows them to add that ics to their Google calendar.

Issue:  When the appointment is close to a daylight savings time, the google calendar option is adding the appointment 1 hour later than the appointment. Please see the below,

Appointment time - Oct 31 @6 PM – 6.15PM EDT. But, in google it shows as 4.30am – 4.45am IST instead of 3:30am-3.45am IST. (please see the attachment - IST Time format)

Appointment time - Oct 31 @6 PM-6.15 PM EDT. But, in google it shows as 4pm – 4.15pmIST instead of 3pm-3.15pm IST.(please see the attachment - PDT Time format)

Code

The time zone will be PDT, EDT, CDT – and it will erroneously add 1 hour to the appointment(.ics file) and the time zone will say PST, EST, CST  and it will show the correct time

The actual .ics file is being generated using a Telerik library. That’s the one that is creating these RRULE entries in the .ics file.
So, different time gives in google and outlook using this .ics file? How to resolve this ?

Thanks,
Srinivasan

Hi,

I want to override the select all filtering in radgridview to avoid stack over flow exception as mentioned below

Is there a way I can create custom list and change the item source? 

Hi!

I am using a pivot grid, with a PivotFieldsList, and would like to be able to allow the user to choose a custom column name when hey are setting up there table. Whilst I can set the name correctly from the backend: I was hoping to allow someone to set the name from the drop down box. I have attached a *rough* image to demonstrate what I am trying to achieve.

Thanks for your help!

Hey guys,

I have following Usercontrol with a RadGridView.

The Itemsource of it is a DataView with SQL-data.

I have now applied a RowStyleSelector and with this occured a problem: The first row is always not really selected, but highlighted. I added a picture of it.

If I click the row gets really selected and the Style gets applied. I don't seem to have this problem with Bindings to Observable Collections. But completely convert the Dataview to another Collection seems to be really time consuming.

If I set IsSynchronizedWithCurrentItem to false, it works, but I not really want to miss the Indicator.

This: grid.Loaded += new RoutedEventHandler((sender, e) => { (sender as RadGridView).CurrentItem = null; }); changes nothing.

Setting the SelectedItem to the first DataRowView initially also not works.

Has anyone any other ideas?

Greetings,

Hi All,

I have tabcontrols with two tabs and each tab has comboboxes. On initial load everything is working as expected but if i change tab automatically focus sets to combobo control. 

I want to prevent auto focus element tab onchange, please see below sample code to reproduce issue.

<telerik:RadTabControl>
            <telerik:RadTabItem  Header="Location">
                <telerik:RadTabItem.Content>
                    <StackPanel>
                        <telerik:RadComboBox Width="200" x:Name="item1" Height="50" IsEditable="True"   EmptyText="Select"  >
                            <telerik:RadComboBoxItem Content="Item 1" />
                            <telerik:RadComboBoxItem Content="Item 2" />
                        </telerik:RadComboBox >
                        <telerik:RadComboBox Width="200" x:Name="item2" Height="50" IsEditable="True"  >
                            <telerik:RadComboBoxItem Content="Item 1" />
                            <telerik:RadComboBoxItem Content="Item 2" />
                        </telerik:RadComboBox>
                    </StackPanel>

                </StackPanel>
            </telerik:RadTabItem>
        </telerik:RadTabControl>

Any help would be appreciated,

Hi All,

I am using RadGridView with MVVM binding. I am pulling large amount of data i.e.5000 records from database so used BackgroundWorker for data processing.

In RunWorkerCompleted event  i am assigning data to ObservableCollection which is my grid's ItemsSource.

Everything works well except rowindicator, it's not visible if i bind data in worker completed event.

If i remove background worker and execute process on main thread then rowindicator displayed on grid.

Here is my sample code;

  public ObservableCollection<Assets> AssetDs { get; set; } = new ObservableCollection<Assets>();

   private voids search()
        {

          BackgroundWorker bw = new BackgroundWorker();

           bw.DoWork += (sender, e) =>
                {
                   e.Result = //DB call to fetch records 
                };

            bw.RunWorkerCompleted += (sender, e) =>
                {

                     List<Asset> result = (List<Asset>)e.Result;

                     result.ForEach(a => AssetDs.Add(a));

                 }

               bw.RunWorkerAsync();

          }

Any help would be appreciated,

Hi All,

What is the best approach to notify required combobox on button click? I have a form with 4 tabs and each tab has some mandatory fields.

If user clicks on button i want to validate all tabs and notify user with highlighting required controls. 

Looking for possible solutions for above workflow.

Any help would be appreciated,

Hi guys,

I have a PivotGrid with a LocalDataSourceProvider.

The Itemsource of this LocalDataSourceProvider is a ObservableCollection.

I set these Descriptions:

            Telerik.Pivot.Core.PropertyGroupDescription pgdKWJahr = new Telerik.Pivot.Core.PropertyGroupDescription();
            pgdKWJahr.PropertyName = "KWJahr";
            pgdKWJahr.SortOrder = SortOrder.None;
            Telerik.Pivot.Core.PropertyGroupDescription pgdBearbeiter = new Telerik.Pivot.Core.PropertyGroupDescription();
            pgdBearbeiter.PropertyName = "Bearbeiter";
            PropertyAggregateDescription padAnzahl = new PropertyAggregateDescription();
            padAnzahl.PropertyName = "Anzahl";

            using (ldspAnzahlÜbergabeWerk.DeferRefresh())
            {
                ldspAnzahlÜbergabeWerk.RowGroupDescriptions.Add(pgdKWJahr);
                ldspAnzahlÜbergabeWerk.ColumnGroupDescriptions.Add(pgdBearbeiter);
                ldspAnzahlÜbergabeWerk.AggregateDescriptions.Add(padAnzahl);

            };

If the ObservableCollection now changes, I have to call a Refresh on the LocalDataProvider:

UcReklamationsAnzahlÜbergabeWerkVerlauf.ldspAnzahlÜbergabeWerk.Refresh();

This is not that great, but works if a value changes.The problem is, it not triggers anything if a new item should appear or an item is removed.

For better understanding:

My Collection is a list of how much things a user in each week completed. If someone now changes the weekrange, there should appear the new weeks in this range.

Is there any possibility to achieve this?

Greetings
