My radGridView numerical columns have thousand separator so I have to put a ',' when I search the grid cells using search row. How can I setup the grid so its search cell has thousand separator when I am looking for numerical values?

My numerical columns values are 5 decimal point:

123.12345

123.1234

123.123

123.12

123.1

123

0.123

and so fourth...

Hi,

I recently read that self-referencing hierarchy is now supported by the radGridView.  Unfortunately, I have been unable to locate any demos, tutorials, or sample code to look at.  Is this information available?

Here is my current code that I'm working with:

Sample data would look like this:

ElementID -- ProtocolTemplateID -- ParentElementID -- ElementNumber -- ElementDesc
1 -- 1 -- 1 -- 1.0 -- ParentLevel1
2 -- 1 -- 1 -- 1.1 -- ChildLevel1
3 -- 1 -- 1 -- 1.2 -- ChildLevel2
4 -- 1 -- 4 -- 2.0 -- ParentLevel2

With my current code, this displays as:

Row 1
-- Row1
-- Row2
-- Row3
Row 2
Row 3
Row 4
-- Row 4

It should be:

Row 1
-- Row 2
-- Row 3
Row 4

Also, another problem is with the portion of code I have commented out.  This code causes a NullReferenceException error to be thrown and I don't know why.

 

If anyone could help me out with the above code, or even point me in the direction of some reading material, I would be very grateful.

Thanks,

Robert

I am facing issue with RadDateTimePicker.Is it possible to enter only two digit in the year part like if i enter 16 than it will be consider as 2016 not to enter 2016? If i enter 16 than it will consider as 2016 and if i enter 2016 than it will consider same 2016. please check below code i used for RadDateTimePicker

Public Sub New()
        Me.New()
        Me.CustomFormat = "MM/dd/yyyy"
        AddHandler Me.LostFocus, AddressOf radDateTimePicker1_LostFocus
        Me.Font = New System.Drawing.Font("Tahoma", 8.25!)
        Me.Format = System.Windows.Forms.DateTimePickerFormat.Custom
        Me.NullText = "  /   /"
        Me.Size = New System.Drawing.Size(80, 19)
        Me.Value = New Date(CType(0, Long))
        CType(Me.DateTimePickerElement.GetCurrentBehavior(), RadDateTimePickerCalendar).Calendar.FirstDayOfWeek = FirstDayOfWeek.Monday
        CType(Me.DateTimePickerElement.TextBoxElement.Provider, MaskDateTimeProvider).AutoSelectNextPart = True
    End Sub

Private Sub radDateTimePicker1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs)
        Try
            If (Me.Value = "#12:00:00 AM#" Or Date.MinValue = Me.Value.ToShortDateString() Or Me.Value.Year <= 1900) Then
                Me.NullableValue = Date.MinValue
                Me.NullText = "  /  /"
            End If
        Catch ex As Exception
        End Try
    End Sub
 

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.

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"
                    OnAppointmentDataBound="DiaryRadScheduler_AppointmentDataBound" OnAppointmentCommand="DiaryRadScheduler_AppointmentCommand"
                    AllowDelete="false" AllowEdit="false" AllowInsert="false" EnableDescriptionField="true"
                    EnableRecurrenceSupport="false" EnableResourceEditing="false" EnableExactTimeRendering="false"
                    DayStartTime="08:00:00" DayEndTime="20:00:00" WorkDayStartTime="09:00:00" WorkDayEndTime="18:00:00"
                    WeekView-DayStartTime="08:00:00" WeekView-DayEndTime="20:00:00" WeekView-WorkDayStartTime="09:00:00" WeekView-WorkDayEndTime="18:00:00" WeekView-EnableExactTimeRendering="true"
                    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"
                    StartEditingInAdvancedForm="true" StartInsertingInAdvancedForm="true"
                    ShowHeader="true" ShowFooter="true" ShowAllDayRow="false" ShowDateHeaders="true" ShowFullTime="false" OverflowBehavior="Expand"
                    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" />
                    <AgendaView HeaderDateFormat="d" UserSelectable="true" />
                    <TimelineView UserSelectable="false" />
                    <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.
