Hi Team,

I am using server based dynamic radhtmlchart control in my asp.net page. It is getting dynamically rendered and added to the the page. I have a requirement where y-Axis points should be in descending order (Ref: pic 1). I have tried using reversed = true property but it is moving the x-axis to the top of the chart. 

Is there any way i can implement the requirement as shown in the reference picture.

Any sort of help is appreciated.

So I'm trying to do what should be simple... I'm databinding to a grid and want to make simple edits and save.  But I can't get it to work :(  I've tried every combination I can think of and none work.  When I click edit, the edit form opens but no changes save back.  I'm sure it's something simple that I've overlooking but... 

I've tried it a few ways, this is an example:

 And my data is as follows:

Hi!

AddFileInput - adds a row at the end of the control.

How can I add a row in a particular place in the middle?

Thanks

Hello, I have a chart created with ScatterLineSeries. Everything works, except the color inside the markers is white. I'd like it to be filled with the same color of the marker's outline.

Is there a property to fill inside the marker "automatically". when the chart or the series is first created ?

I am aware of there are SeriesItem.BackgroundColor and series.MarkersAppearance.BackgroundColor properties; However, I need to fill the markers automatically (when the chart is first created), since the different (mutliple) series get different colors and I can't tell what color will the series be.

I am attaching a screenshot

Thank you

hi, I have a radchart and want to show multiple lines using sql data source. User selects date range from calendar (raddatepicker) after that select points from radcombobox and I query the database for those range with three parameters (first date, second date and name point), naturally this is all handled by RadAjaxManager.I'm aware that in radhtmlchart not supported datagroupcolumn. How to do it radhtmlchart with multiple line series.

This is my code ASPX with radchart setting and RadAjaxManager:

<telerik:RadDatePicker runat="server" Visible="true" ID="dpIN"></telerik:RadDatePicker> &nbsp;&nbsp; <telerik:RadDatePicker runat="server" Visible="true" ID="dpOUT"></telerik:RadDatePicker>
    <telerik:RadComboBox ID="rcb_point" runat="server" AutoPostBack="True" DataSourceID="dsPoints" Width="300px"
            DataTextField="name_point" DataValueField="id" 
            AppendDataBoundItems="true">
            <Items>
                <telerik:RadComboBoxItem Text="Все точки" Value="0" Selected="true"></telerik:RadComboBoxItem>
            </Items>
        </telerik:RadComboBox>

<telerik:RadChart ID="RadChart2" DataSourceID="SqlDataSource1" runat="server"
                        Width="1500px" Height="800px" DefaultType="Line" OnItemDataBound="RadChart1_ItemDataBound" 
                        AutoLayout="true" AutoTextWrap="true" CreateImageMap="false">
        <ChartTitle>
            
        </ChartTitle>
        <Series>
            <telerik:ChartSeries DataYColumn="param_d" Name="передача данных" Type="StackedLine">
                <Appearance LegendDisplayMode="ItemLabels">
                    
                </Appearance>

            </telerik:ChartSeries>

        </Series>
    </telerik:RadChart>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionInfo %>" SelectCommand="RetrieveChart" SelectCommandType="StoredProcedure">
    <SelectParameters>
        <asp:ControlParameter ControlID="rcb_point"  Name="point_id" PropertyName="SelectedValue" Type="Int32" />
        <asp:ControlParameter ControlID="dpIN" Name="date_in" PropertyName="SelectedDate" Type="DateTime" />
        <asp:ControlParameter ControlID="dpOUT" Name="date_out" PropertyName="SelectedDate" Type="DateTime" />
    </SelectParameters>
</asp:SqlDataSource>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel" runat="server" />
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" EnableAJAX="true" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
      <AjaxSettings>
          <telerik:AjaxSetting AjaxControlID="rcb_point">
              <UpdatedControls>
                  <telerik:AjaxUpdatedControl ControlID="RadChart2" LoadingPanelID="RadAjaxLoadingPanel1" />
                  <telerik:AjaxUpdatedControl ControlID="rcb_point" />
                  <telerik:AjaxUpdatedControl ControlID="dpIN" />
                  <telerik:AjaxUpdatedControl ControlID="dpOUT" />

              </UpdatedControls>
          </telerik:AjaxSetting>
      </AjaxSettings>
  </telerik:RadAjaxManager>
 <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
 </telerik:RadAjaxLoadingPanel>

And this is my C# code:

       protected void Page_Load(object sender, EventArgs e)
        {
            RadChart2.DataGroupColumn = "sensor_type";
            RadChart2.PlotArea.XAxis.DataLabelsColumn = "date_in";
            RadChart2.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 300;
            RadChart2.PlotArea.Appearance.Dimensions.Margins.Bottom = Telerik.Charting.Styles.Unit.Percentage(30);
        }

Bellow i will attach two picture: my structure data table, i need to form multiple line series a column "sensor_type", and this is what i have right now.

Thank you for your attention, i hope upi will help me.

Hello!

1. How can I set the temporaryFolder to be in the MemoryStream?

2. I am using the control dynamically. That is, one control has several file selection buttons. The problem is that if the user wants to cancel / remove the file that is uploading then the entire line is deleted. How can I cancel / delete only the file and not the entire line (which has a title and a select button)?

Thanks

I'm looking to get my site up to WCAG 2.0 AA and I have a RadAsyncUpload control:

<telerik:RadAsyncUpload ID="mfUpload" runat="server" MultipleFileSelection="Automatic"  RenderMode="Auto" Skin="Bootstrap"
                                                OnClientFileUploadFailed="failed" EnableViewState="false" OnClientFilesUploaded="OnClientFilesUploaded"
                                                OnClientFileUploading="OnClientFileUploading" EnableAriaSupport="true"
                                                AllowedFileExtensions="jpg,png,gif,pdf"  DisablePlugins="true"  OnClientFileSelected="OnClientFileSelected"
                                                OnClientFileUploadRemoved="removed"   OnClientFilesSelected="onSelect"  OnClientValidationFailed="OnClientValidationFailed"  
                                                OnClientAdded="added"    Localization-Select="<%$ Resources:GlobalResource, SelectTitle %>"
                                                Localization-Cancel="<%$ Resources:GlobalResource,CancelText %>"  
                                                Localization-Remove="<%$ Resources:GlobalResource,RemoveText %>"  EnableInlineProgress="true">
                                
                            </telerik:RadAsyncUpload>

AriaSettings don't seem to be available and I need to set a label to the form element (upload control).  I set the EnableAriaSupport=true but I don't think that's going to solve my problem.

What are my options?

On C#/ASP.NET I am creating a graph that I am putting dates on X axis; however, the dates are only being displayed on the major ticks. Does RadHtmlChart have a setting to display dates on minor ticks as well  ?

I am attaching a screenshot.

Thanks
