I am trying to check whether Telerik chart Is the best chart for me.
I wrote a small application which shows 1000 line graphs with around 1000 points on each graph.
My performance is really lousy.
Did anyone ever tried to this ?

My Mapping is done like this:
            RadChart1.DefaultView.ChartArea.EnableAnimations = false;
            RadChart1.DefaultView.ChartArea.EnableTransitionAnimations = false;
            RadChart1.DefaultView.ChartArea.AxisY.MaxValue = 100;
           
            
            RadChart1.DefaultView.ChartLegend.MaxWidth = 100;
            LineSeriesDefinition lineSeriesDefinition = new LineSeriesDefinition();
            lineSeriesDefinition.ShowItemLabels = false;
            lineSeriesDefinition.ShowPointMarks = false;
            lineSeriesDefinition.ShowItemToolTips = false;
            ItemMapping itemMappingX = new ItemMapping();
            itemMappingX.DataPointMember = DataPointMember.XValue;
            itemMappingX.FieldName = "DoubleData";
            ItemMapping itemMappingY = new ItemMapping();
            itemMappingY.DataPointMember = DataPointMember.YValue;
            itemMappingY.FieldName = "DoubleData2";
            
            for (int i = 0; i < multiObservableCollection.Count; i++)
            {
                SeriesMapping seriesMapping = new SeriesMapping();
                seriesMapping.CollectionIndex = i;
                seriesMapping.SeriesDefinition = lineSeriesDefinition;
                seriesMapping.ItemMappings.Add(itemMappingX);
                seriesMapping.ItemMappings.Add(itemMappingY);

                this.RadChart1.SeriesMappings.Add(seriesMapping);
                Console.WriteLine(String.Format("Adding series {0}", i+1));
                
            }

I Think there is a Bug in RadNumericUpDown

I have an ErrorTemplate that shows an Info popup when the Control is focused, it dont works with the RadNumericUpDown.

IsFocused is always false.

I'm trying to set an appointment's default value for TimeMarkerID for new appointments.  When I add code in either the SqlAppointment's constructor or ViewModels' OnAppointmentsCollectionChanged and then hit the save button on the appointment it appears to try and save the appointment twice.  The second appointment has all values blank except for the timemarker default value.  I then get an exception of 'The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.' because the start/end times are 1/1/0001.

Note: Neither appointment actually saves to SQL.

Is there a way to set the default value of TimeMarkerID?

Thanks,

Hi,

I have an AutoCompleteBox where the selection mode is set to single, I wish to set focus on the next control when the enter key is selected when the AutoCompleteBox has a value selected.  Is this possible?

Hi,

 

I'm using actually a behavior to block the resize feature of an appointment but when I try to resize an appointment, the resize cursor become visible even if the resize feature was blocked!!!

Hello,

How do I get the GridViewGroupRow from the grid? There is a post here http://www.telerik.com/forums/radgridview-opening-groups-programmatically that indicates you can do this through the radgridview.Items.Groups, but this returns an IGroup, which does not have the IsExapnded property that GridViewGroupRow object has.

I would like to loop through the groups and expand/collapse groups based on certain criteria, but I don't know how to get the GridViewGroupRow.

 

Thanks,

Scott

Hi All

 We have a telerik datagrid wherein we define a row validity based on properties of other rows (objects).

 so as soon as one row's validation fails, all the related row turn red as well, but when we make data changes to pass the validation, the row under edit turns back to normal color but others still remain RED.

 So my question is, when all rows turn red as soon as their validation fails why they don't turn back to normal as soon as validation passes ?

 

Thanks

Hi

In Visual Studio, Chrome, Firefox, and all other apps that support tabbed windows with docking and floating, it is possible to grab the tab of a window, and move it left or right along the tab row, in order to change the tab ordering. The window only undocks if you move the mouse outside of the tab row area.

Can this behaviour please be implemented in RadDocking? At the moment, as soon as you grab a tab and move it, it undocks. I think the behaviour should be made to be more in line with other applications that support docking/floating/tabbing.

Thanks

Hi,

I want to place the controls just beside the minimize button of the ribbon view.

We can see few controls near the minimize button in VS2013. I have attached the screenshot.

Please help us to place the controls as the same way.
