I'm using RadPdfViewer control, and it works correctly if I write my code like this:


But I want to load files that are hosted on a server (within the same network). I tried this:


As a test, I try a local file


Is there a way to do it?

PS: All the files have read permissions are published

Hi all.
I'm using the QueryableCollectionView to filter mu RadChart. With this class i'm able to retrieve the original collection of data (using the SourceCollection property). But, how i can retrieve the filtered collection of data?
Thanks in advance

Getting error like "The tag 'RadComboBox' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation" this.

This is my coding

I have tried to implement a line chart along with Notes,. but the problem arises when 2 notes are very close to each other they overlap and are not readable. I tried adding margin but could not achieve a good result even with rotation it looks very absurd. 

I am trying to figure out a way where I can display the notes in one series alternatively top or down. But I can't find anything. I only got an option to display notes top or down per series. Need help with this?

Or if any other way I can achieve it with a readable format

While viewing a virtual collection in the gridview if I load the first page, select a row, then move down to a page after the second page and attempt to close the multi selection with the shift key (multi-select across pages) the following error is thrown, any way to prevent this short of removing extended selection from the grid (currently have functionality tied to multiselect), maybe reset selection when page moves?:

Hi,

I have a grid with a lot of columns (20+) and when you sort on the column the horizontal scroll bar resets to the left most position which often hides the column you just sorted (or filtered) on.  I read this was fixed in the Q3 2010 build which we have installed, but the problem persists.  Note, we also freeze several of the columns.

I am hoping you have some examples of using the Stacked Bar Chart with databinding in XAML to a MVVM Property.  What I am trying to do is create a chart with "Month" along the horizontal access and to series ("Planned" & "Actual") and then stack the values by the "GroupLvl" Column

GroupLvl	Xcat	Planned	Actual
CENTRAL	NOV	30	45
CENTRAL	OCT	0	1
CENTRAL	SEP	0	0
CENTRAL	YTD	0	1
SOUTHEAST	APR	0	1
SOUTHEAST	AUG	1	0
SOUTHEAST	DEC	1173	6840
TENNESSEE/KENTUCKY	NOV	3560	3231
TENNESSEE/KENTUCKY	OCT	2126	3869
TENNESSEE/KENTUCKY	SEP	2756	2174
TENNESSEE/KENTUCKY	YTD	1537	2634

here is what I have been trying in XAML, but I am still far from the desired mark.

 

 

 

 

 

 

any help you can provide would be greatly appreciated.

Is it possible to retrieve the position of the mouse on the ruler? I would like to display it in decimal in my control.

Hello.

I need update value of RadGridView GridViewCell then she in Edit Mode.

I use MainGrid.BeginningEdit event:

private void MainGridOnBeginningEdit(object sender, GridViewBeginningEditRoutedEventArgs args)
        {
            if(args == null || args.Cell.Value != null) return;

            if (BeginningCellEditEvent != null)
                BeginningCellEditEvent.Invoke(args);
        }

In BeginningCellEditEvent handler i try set new cell value:

private void ActivityDateFactTable_OnBeginningCellEditEvent(GridViewBeginningEditRoutedEventArgs args)
        {
            if((args?.Cell == null || args.Cell.Value != null)) return;
            if(!(args.Row.DataContext is ViewModel viewModel)) return;

            var bindingPath = args.Cell.DataColumn.DataMemberBinding.Path
                                                                            .Path
                                                                            .Replace("[", "")
                                                                            .Replace("]", "")
                                                                            .Split('_');
            if(bindingPath.Length < 3) return;            
            var calcValue = viewModel.GetCalculatedValue(bindingPath[0]);
            if (calcValue != null)
            {                
                args.Cell.Value = calcValue;                
                args.Cell.UpdateLayout();
            }
        }

or

private void ActivityDateFactTable_OnBeginningCellEditEvent(GridViewBeginningEditRoutedEventArgs args)
        {
            if((args?.Cell == null || args.Cell.Value != null)) return;
            if(!(args.Row.DataContext is ViewModel viewModel)) return;

            var bindingPath = args.Cell.DataColumn.DataMemberBinding.Path
                                                                            .Path
                                                                            .Replace("[", "")
                                                                            .Replace("]", "")
                                                                            .Split('_');
            if(bindingPath.Length < 3) return;            
            var calcValue = viewModel.GetCalculatedValue(bindingPath[0]);
            if (calcValue != null)
            {    
                this.Dispatcher.BeginInvoke
                ((Action) delegate
                    {
                        args.Cell.Value = calcValue;
                        args.Cell.UpdateLayout();                   
                    }
                );
            }
        }

Cell.Value is changed, but in UI not updated (as seen on screenshot).

How i can update value in UI after changing him in code and i need that cell stays in edit mode?
