I use for loop to loop 100 records and bind the DataTable(certain fields only) to the gridview. When I saw the gridview, there is a lot of empty rows will show at the bottom of last records. Also, the scroll bar still can scroll for the blank rows. I also set the page size as 20 to make the maximum rows of a page to 20 rows. Please find the attachment(see the red color box for the empty area) for the reference.

Code:

    for (int z = 0; z < 100; z++)
            {

                this.radGridView1.Rows.Add(table.Rows[z][1], table.Rows[z][2]);

            }

Hello,

I use Radscheduler and datas are loaded from a dataset that directly calls an Oracle database through the Oracle Client and it works well.

I need to replace this loading by a webservice call.

The first ​loading is ok and I have my appointments and all my other data but when I move an appointment, the change is not reflected in the datatable so I can not intercept these changes.

I use DataRowVersion.Original ​to get the previous version of the appointment but that does not work when datas are loaded from the webservice.
When data is loaded from the dataset methods it works correctly.

Everything works by loading the data using the methods of the dataset :

1.Me.ResourcesTableAdapter.CustomFill(...)
2.Me.AppointmentsResourcesTableAdapter.CustomFill(...)
3.Me.AppointmentsTableAdapter.CustomFill(...)


But it does not work by loading the data from the webservice (just replacing the loading calls)

1.Me.Planning.Merge(WebserviceCall(...))
2.Me.Planning.Merge(WebserviceCall(...))
3.Me.Planning.Merge(WebserviceCall(...))

Data load correctly and appointments appear good.
Moving an appointment is however not impacted on the datatable match.

 

For information : bindings ​are like that  : 

1.SchedulerBindingDataSource.EventProvider.AppointmentFactory = Me.RadScheduler1.AppointmentFactory
2.SchedulerBindingDataSource.EventProvider.DataSource = Me.Planning.Appointments
3.SchedulerBindingDataSource.ResourceProvider.DataSource = Me.Planning.Resources
4.Me.RadScheduler1.DataSource = Me.SchedulerBindingDataSource

Do you have an idea of the problem and how to solve it ?

Thank you.

Merci.

Hello Telerik,

 I need your expertise on a situation about one GridView.

The gridview display a daily rows with a running value (3 column Date, Value, RunningValueOfValue). As it is a daily row with a few year of historical data there is a couple of thousand row in the datasource. As there is a running value, a change on one row should also update all following row.

The datasource of the grid is a WCF Service. On CellValueChanged, I send the modification to the service which will return the new set of data (as an array) for all row (The calculation of the running value is made in the WCF Service). Then I have tested two options :

  1. I set the new array as the datasource of the grid. It is fast but the position of the grid is set back on top and I don't think my user will be happy about it.
  2. I use the new array to update each object in the actual binding source. It is very slow (more than 1 min) because the binding list raise a lot of event for updating the gridview (depending on the size). If I play with RaiseListChangedEvents and ResetBindings, it become fast again but the ResetBindings will have the effect as changing the datasource...

What is the best way to handle this kind of situation ? Using an unbound datagridview ?

Hi,

 I try to use a custom image to replace the default arrow icon used to navigate in the hierarchical structure in RadGridView winform control.

No problem to set the image the cellElement does not fit to the image size.
Here's my code :

private void MyGridView_ViewCellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
       {
           Telerik.WinControls.UI.GridGroupExpanderCellElement cellElement = e.CellElement as Telerik.WinControls.UI.GridGroupExpanderCellElement;
                        
 
           if (cellElement != null)
           {
               
               cellElement.Expander.SignSize = new System.Drawing.Size(30, 30);
               cellElement.Expander.SignImage = Properties.Resources.MyCustomImage;
               cellElement.Expander.SignStyle = Telerik.WinControls.UI.SignStyles.Image;
           }
 
 
       }

       The cellElement.Expander.SignSize seems to have no effect.

 How can I achieve this please ?

 Thanks.

Hello, is there a way to change the arrow size of a radpopupeditor ?

I tried the following, that changes the dropdown button size but I cannot find a way to edit the arrow size, the problem is that (on windows 10, 4k monitor, 200dpi screen) the arrow is almost invisible.

radPopupEditor1.PopupEditorElement.ArrowButtonElement.Size = getSizeByUnit(4.5F,6.35F); <--this works
radPopupEditor1.PopupEditorElement.ArrowButtonElement.Arrow.Size = getSizeByUnit(2, 2); <--no effect.

Best regards

Andrea

Tried In both Windows 7 and Windows 10.  Set "Auto Hide Taskbar" in windows, so that the bottom task bar slides up when the mouse is ran over the bottom of the screen.  Using regular apps in full screen, this still is functional.  Using a Telerik ShapedForm (Winforms) in full screen prevents the task bar from sliding up.  Has anyone experienced this, or have a solution?

Hi
It would be good to have the splash screen form that is part of your sample application available as a component for us to use in our applications.  

I was going to reflect your assemblies, but decided that this would probably contravene the licence.

Other features that would be useful would be to have dynamic text (text that could be set while the application is being loaded) as well as a progress bar to indicate where in the load the process is.

Best regards

I have two classes

One is EQConfig, the other is HSMSConfig (I attached) and EQConfig has a property which name is hsmsConfig and HSMSConfig type.

Then, I set below

this.radPropertyGrid1.SelectedObject = EQConfig;

Then I expected I can expand hsmsConfig property like

Hi folks,

i am working on a project where is want to plot multiple lineseries to compare racing times off different drivers on track during a race.

My problem is that i don't know the number or the maximum number of drivers on track at design time.

Of course i could add several series at runtime and simply don't fill the unused, but how can i manage this from code let's say in a For Next Loop.

Suggestion in vb would be nice. Using

        Dim lineSeries As New LineSeries()
        For id = 0 To arrFahrer.Count - 1
            For i As Integer = 0 To arrFahrer(id).douRundenZeiten.Count - 2
                rcvRundenzeiten.Series(id).DataPoints.Add(New CategoricalDataPoint(arrFahrer(id).douRundenZeiten.Item(i)))
            Next i
            rcvRundenzeiten.Series.Add(lineSeries)
        Next

just creates one series with all points.

Kind regards

 Martin
