I have a DLL that gets loaded into a desktop application that contains several WPF controls that use the Telerik RadDateTimePicker, RadListBox and RadAutoCompleteBox controls.  When the desktop application creates the tabbed window that these controls are used on, none of them a visible and I am receiving the following exception:

The type initializer for 'Telerik.Windows.Input.Touch.TouchManager' threw an exception.

There are no Themes being used in these WPF controls/windows.  I am at a complete lose about what is causing this, please help.

I am adding to my project and hourly choice and also a minutes.  So the user can set the recurrence to happen every x amount of hours or every x amount of minutes.  But when setting either of these, the UI doesn't show the recurrences after the editrecurrence box closes.  I have attached a sample application I made that shows.  Open Recurrence and pick like every 2 hours.  Nothing will happen after you close the dialog.  But if you then open it back up and change the resources or do another UI function, then they will show up. How do I fix this?

I am trying to get a gridviewcombobox to filter and it does not work as documented. 

The properties have different names than the combobox documentation and some properties are not the same as a combobox. 

I tried setting the edit panel style as suggested in the reply to another post, but when I do that the edit panel does not appear and the combo box does not function at all. I have the following code:

 <telerik:GridViewComboBoxColumn Header="Parent"
                                                IsComboBoxEditable="True"
                                                ItemsSource="{Binding AllFinishedProducts, Source={StaticResource finishedProduct}}"
                                                FilterMemberPath="PartNumber"
                                                DataMemberBinding="{Binding ParentId}"
                                                SelectedValueMemberPath="Id"                  
                                                DisplayMemberPath="PartNumber">

The current behavior is more like a search than a filter. How can I get a gridviewcomboboxcolumn to filter like a radcombobox?

Hello there folks,

I have an issue with a RadGridView and GridViewNewRow.

I have a RadGridView bound to an Itemssource (ICollection). Every row is expandable with a DetailsTemplate for Read-Only and Edit. So far everything works fine. Problems arise when I enable the "NewRow" option of the GridView.

The GridViewNewRow uses the same DetailsTemplate as the Edit Template but for some strange reason the built-in ScrollViewer of RadGridView works differently for the GridViewNewRow. The content of the GridViewNewRow gets recognized and shown (all Height and Width properties are set to Auto/NaN), but the content is not scrollable, so if the new row gets activated near the bottom of the GridView, the content flows outside of the visible area and you have no possibility to focus it there.

Expanding the DetailsTemplate of the Read-Only or Edit Template works perfectly with the scrolling. So basically you can add a new row on the bottom of the GridView and you can only see half of the content, then you commit the row and go to edit mode of the same row (which uses exactly the same template) and you can scroll like a young god. I added two pictures showing the explained behavior, GridViewNewRow without the ScrollBar and GridViewRow with the ScrollBar, both using the same template with the same data, but one working and the other not so much.

I did some digging inside the properties and saw that the IScrollInfo.ExtentHeight of the RadGridView does not recognize the expanding of the Details Template of the GridViewNewRow while it does recognize the expanding of the GridViewRow. So there might be some error at this point. I attach an event handler to the "AddingNewDataItem" in the RadGridView to set the DataContext, but otherwise everything is out-of-the-box "Telerik" usage and I never enable/disable the ScrollViewer in any way.

Any ideas where the problem might be? Is there some property you have to set for GridViewNewRow?

Thanks !

Hi,

Performances of ChartTrackBallBehavior isn't good when I work with a lot of series (20/30) with a lot of points (>20.000 each).
In effect I cant ensure conditions for a good implementation of "Get Closest" functions because my datapoints is always ordered.

Exists a strategy for inform series that Dataset is ordered or override GetClosest functions?

Thank's marc.

i want to have a scroll to be added in the submenu item list.
if im making radmenuItem.DropDownHeight = 200, then i can achieve wat want. 
but issue arise when the submenu item are less(say2), then submenuitem list shows 2 submenu item and rest space is show blank, ie. it takes minumun height to the submenu item list as 200.

FUNCTION: 
  private void AddtoReporMenuItem_OnMouseEnter(object sender, MouseEventArgs e)
        {
            var treeViewModel = this.DataContext as TreeViewModel;
            if(radcontextMenu.Items.Count>2)
                radcontextMenu.Items.RemoveAt(2);
            RadMenuItem  reportItem = new RadMenuItem(){Header = "Add to Report"};
            RadMenuItem reportNamesItem;
            RadMenuGroupItem reportsList = new RadMenuGroupItem();
            if (treeViewModel.Reports != null)
            {
                foreach (var report in treeViewModel.Reports)
                {
                    reportNamesItem = new RadMenuItem();
                    reportNamesItem.Header = report.ReportName;
                    reportNamesItem.Click += (senderObj, eventargs) => reportItem_Click(senderObj, eventargs, report);
                    reportsList.Items.Add(reportNamesItem);
                }
               
                reportItem.Items.Add(reportsList);
                reportItem.DropDownHeight = 200;
                radcontextMenu.Items.Add(reportItem);
            }

        }




xaml:
   <telerik:RadContextMenu.ContextMenu>
                <telerik:RadContextMenu x:Name="radcontextMenu" MouseEnter="AddtoReporMenuItem_OnMouseEnter">
                    <telerik:RadMenuItem Header="{localization:Translate DeleteTxt}" Command="{Binding Path=DeleteChartDash}" />
                    <telerik:RadMenuItem Header="{localization:Translate ExportButton}">
                        <telerik:RadMenuItem Header="CSV" Command="{Binding Path=ExportCommand}" CommandParameter="ExportChart" />
                        <telerik:RadMenuItem Header="{localization:Translate ExportdataTxt}" Command="{Binding Path=ExportCommand}" CommandParameter="ExportData"  />
                        <telerik:RadMenuItem Header="{localization:Translate PowerPointTxt}" Command="{Binding Path=ExportCommand}" CommandParameter="ExportPPT"  />
                        </telerik:RadMenuItem>
                </telerik:RadContextMenu>
            </telerik:RadContextMenu.ContextMenu>

Hello

Is there a way to lock a radDiagramItem so the user won't be able to move it?

I've already disabled the item's dragging, but the user can still  change the position through Ctrl+Arrow Keys.

I am looking for option similar to 'Hide Field' available in Ajax on a field selected in pivot field list.
I  want the user to  be able to select a field in the pivotfieldlist. But then have an option to hide it from the pivot grid view.

At the moment I can hide a field using AutoGenerateField  which hides it completely from both pivotfieldlist and pivotgrid.
