I am using a scatter chart now, and trying to allow the user to select multiple points to turn them on or off. Using the selection mode of "MultipleDataPoints" doesn't seem to work for scatter charts the way the "documentation" implies for the pie charts. When I get the "SelectedPointChanged" event, either I don't understand the purpose of the "NewSelectedPoint" and "OldSelectedPoint", or they aren't working. Basically if I have 5 points 1,2,3,4, and 5, if I click on point 2 and then 3 it gives me new point 3 and old point 2. I would expect not to get an old point called out until I "deselect" a point. Otherwise I don't see how to accomplish what the example shows, with two points offset from the center when the multiple points is selected. Rather than banging my head against the wall on this, I used the custom renderer and hit test method on mouse down method that you showed me to fix the multiple pie selection issue, so I have it been able to accomplish what I need but I would still like to know what I am supposed to do in that situation, or if multiple data point selection is just not supported for scatter charts.

My more pressing issue is that I am now trying to use the lasso selection. However I don't want to zoom. I would like to override the behavior to get the lasso but then do my own action on the lasso'd points (the selection I am doing above, actually). I tried inheriting the class but all of the obvious calls that I could override had no effect.

Alternatively, or perhaps in addition to, I would like to know how to determine what points are in the zoomed area once lasso'd. For double bonus, I would like to be able to lasso a circle with the radius emanating from the moused down point (the radius at the mouse up point).

Hi,

I have a dataGrid with a threestate Checkbox-Column. Off = 0, On = 1, Indeterminate = 2.

State Off and On ok, but Indeterminate only the last is show correctly.

After fill the dataGrid On and Indeterminate always the same. I don't know what is wrong.

Database Columns are:

Code varchar(10)
Description varchar(50)
Sort tinyint  (0=off,1=on,2=indeterminate)

Fill datagrid:

private bool LoadStreets()
        {
            bool bOk = true;
            try
            {
                context.Street.Load();
                bindingSourceStreet.DataSource = context.Strassen.Local.ToBindingList();
            }
            catch (DbEntityValidationException ex)
            {
                bOk = false;
            }

            return bOk;
        }

Please can you tell me what is wrong?

Thank you

Andreas

it is super weird. I spend over 4 hours 

my project has very simple data table :

date,quantitysold,AverageQuantity,  in datatime, int, int

date will be X

quantitysold, averageQuantity, will be Y1 and Y2

first, user will get the product ID table into gridview and when choosing the product to show the chart,

the radchartview should popup/update the chart based on the product PID

I could make it work when I click the first product ID, erverything is ok, but more I click the datagrid to view the product sales data , the chartview becomes more smaller, please refer to the screenshots

everytime I click the data, I first make series.clear(), and tested area clear(), chart refresh, update.

   private void radGridView_197_data_CellClick(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
        {
            this.radChartView_197_chart.Series.Clear();
            this.radChartView_197_chart.Area.Series.Clear();
            this.radChartView_197_chart.Refresh();
            this.SetChartViewData();
         //   if (gridview_197_firstClick)
            this.SetupChartView();

....more other code here ,

....

               CartesianArea area = this.radChartView_197_chart.GetArea<CartesianArea>();
                area.ShowGrid = true;
                CartesianGrid grid = area.GetGrid<CartesianGrid>();
                grid.DrawHorizontalStripes = true;

...............more code here to update the table which is every time different because product id changed.

 this.radChartView_197_chart.DataSource = table;
         
            this.radChartView_197_chart.Update();
            this.radChartView_197_chart.Refresh();

}
          

there is no zoom related setup , I tried almost everything, but there is very limited source online to bind the new data source.

please let me know how to do this.

Hi, I want to custom a diagramtoolbox item, how to do it with UI for WinForms?

Hello,

when following this example: http://demos.telerik.com/aspnet-ajax/scheduler/examples/overview/defaultcs.aspx,

I have noticed that the RadCalendar1 doesnt synchronise the RadSchedular,

Really, i didnt use the same RadSchedular (witch binds with web service), i have used a datasource for binding

the mine is:

1) .ASPX

 <telerik:radscheduler runat="server" id="RadScheduler1"
                    DataKeyField="ID" DataSubjectField="Subject" DataStartField="Start" DataEndField="End" DataDescriptionField="Description"
                    DataRecurrenceField="RecurrenceRule" DataRecurrenceParentKeyField="RecurrenceParentId" DataReminderField="Reminder"

                    MultiDayView-DayStartTime="08:00:00" MultiDayView-DayEndTime="20:00:00" MultiDayView-WorkDayStartTime="09:00:00" MultiDayView-WorkDayEndTime="20:00:00" MultiDayView-NumberOfDays="5" MultiDayView-EnableExactTimeRendering="true"
                    AppointmentStyleMode="Auto" SelectedView="AgendaView"

                    RowHeight="25px" RowHeaderWidth="50px" MinutesPerRow="30" TimeLabelRowSpan="2"
                    FirstDayOfWeek="Monday" LastDayOfWeek="Sunday" HoursPanelTimeFormat="HH:mm tt">
                    <DayView HeaderDateFormat="d" UserSelectable="true" />
                    <WeekView HeaderDateFormat="d" UserSelectable="true" />
                    <MonthView HeaderDateFormat="d" UserSelectable="true" />

                    <MultiDayView UserSelectable="false" />
                    <AdvancedForm Modal="true" />
                    <AppointmentTemplate>
                        <%# Container.Appointment.Resources.GetResourceByType("Type").Text%><br /><%# Eval("Subject") %><br /><%# Eval("Description") %>
                        <div>
                            <asp:Button runat="server" ID="BtnExport" CssClass="rsExportButton" ToolTip="Export to iCalendar" CommandName="Export" OnClientClick="Export(this, event); return false;" style="border: none; cursor: pointer;" />
                        </div>
                    </AppointmentTemplate>
                </telerik:radscheduler>

2) .CS

RadScheduler1.DataSource = DataSourceRadSchedular;

Any suggestion please?

Hi,

I am trying to build a RadDocument from many input RadDocuments (to put together many small documents). Many of these smaller documents have numbered lists whose numbering should be preserved. To insert each of the small documents, I am using
     richTextEditorToInsertInto.DocumentEditor.InsertFragment(new DocumentFragment(radDocumentToAppend))

When put together in the bigger document the numbering continues to increase, e.g., if

Document_1 contains:      and       Document_2 contains:
  DOC1_Header                               DOC2_Header
      1.  Doc1_Item1                               1.  Doc2_Item1
      2.  Doc1_Item2                               2.  Doc2_Item2
      3.  Doc2_Item3                               3.  Doc2_Item3
When put together, the resulting document contains
    DOC1_Header 
      1.  Doc1_Item1
      2.  Doc1_Item2
      3.  Doc2_Item3
    DOC2_Header
      4.  Doc2_Item1
      5.  Doc2_Item2
      6.  Doc2_Item3

Is there a way of resetting the start index for list numbering to 1? How can i keep the numbering from the original documents?

Thanks,

Shahrzade.

How can I change the font of DropDownList items?

I have a Scheduler instance in TimeLine view using Resource grouping. I would like to take a radDropdownlist control and give the user the ability to filter the scheduler to just resources he/she is responsible for on the scheduler. Has anyone be able to filter the resources in Scheduler?

Thanks,

Hello,

2.If I want to hide the second row of header and the third row of header , how to do that?

Thanks and regards,
