Chart Performance

We have a com+ component that returns our data from the database in the following format.
This example represents 2 hours of 15min interval data with 4 data series delimited by commas.

We currently use a charting component that can produce a chart with 2 data series (Chart Series)
for 1 year in approximately 4 seconds (From Database query to Client display). That is 4x24x365=35040 points per series.

Will the RadChart (RadControls for ASP.NET AJAX Q2 2010) give us this kind of performance?
if so what would be the best method of loading the data into the chart

1) data binding
2) for loop loading item data

I'm currently seeing about a 15-20sec load time for 2 data series and 800 points using the following sample code.

Thank Marc,

RadChart1.Clear();

// SETTING AXISES

//SetXAxis(0);

RadChart1.PlotArea.XAxis.LayoutMode = ChartAxisLayoutMode.Between;

RadChart1.PlotArea.YAxis.AutoScale = true;

RadChart1.PlotArea.YAxis.Step = 6;

RadChart1.PlotArea.XAxis.AutoScale = true;

RadChart1.PlotArea.XAxis.Step = 10;

RadChart1.IntelligentLabelsEnabled = false;

//SetYAxis(500);

// SETTING SERIES

ChartSeries Series1 = new ChartSeries();

RadChart1.Series.Add(Series1);

Series1.Name = "Electric";

Series1.Type = ChartSeriesType.Line;

Series1.Appearance.LabelAppearance.Visible = false;

ChartSeries Series2 = new ChartSeries();

RadChart1.Series.Add(Series2);

Series2.Name = "Gas";

Series2.Type = ChartSeriesType.Line;

Series2.YAxisType = ChartYAxisType.Secondary;

Series2.Appearance.LabelAppearance.Visible = false;

//Load Series Data

int xSeries=0;

foreach (ChartSeries ChartSeries in RadChart1.Series)

{

for (int i = 0; i < ProcessData.Length - 2000; i++)

{

String[] Channels = ProcessData[i].Split(',');

ChartSeries.AddItem(Convert.ToDouble(Channels[xSeries + 1]));

}

xSeries++;

}

Adding other controls to the RadRibbonBar

I'm hoping that this is an easy question, and that I have just missed finding the answer. Can you add other controls such as the RadTextBox to a RadRibbonBar? I am using VS 2010 and each time I try to add between to the <Items> tags, it gives me an error:

Telerik.Web.UI.RibbonBarItemCollection must have items of type 'Telerik.Web.UI.RibbonBarItem'. 'telerik:RadTextBox' is of type 'Telerik.Web.UI.RadTextBox'

Any help is appreciated.

Thanks.

call client function oncommand column before confirmation

Hello,
I have a radgrid with GridButtonColumn for deleteing row. On clicking the command image, appears radconfirm asking the user if he is sure of the deleting.
I am searching for event(js) BEFORE the confirmation appears on client, because the text of the confirmation depends on the type of the row - some types need text1 and some needs text2.
Witch event can i call?
I tried <clientEvents> of the grid such as: OnCommand, OnRowDeleted but it didnt help - first was shown the confirm and then get in the js function.

thanks,
gila

Loading RadListBox with preselected items linked with RequiredFieldValidator

Hi,

I've got a RadListBox linked with a RequiredFieldValidator from ASP.NET and it's possible this RadListBox loads with preselected items. So, I open the corresponding page and reckon I haven't got to make a change in the selection of the RadListBox and just press my validation button. Unfortunately, I'm getting an error from the validator that I haven't selected a thing in my RadListBox, while there are some items preselected.

My RadListBox looks like:

<telerik:RadListBox ID="DepartmentsListBox" runat="server" CheckBoxes="true" SelectionMode="Multiple" Width="95%" DataSourceID="DepartmentsDataSource" DataTextField="Name" DataValueField="DepartmentID" OnDataBound="DepartmentsListBox_DataBound">

</telerik:RadListBox>

<asp:ObjectDataSource ID="DepartmentsDataSource" runat="server"

SelectMethod="GetDepartments" TypeName="Datamex.Projects.Nebulus.BusinessLogics.Departments">

</asp:ObjectDataSource>

The RadListBox loads like:

protected void DepartmentsListBox_DataBound(object sender, EventArgs e)

{

foreach (RadListBoxItem item in DepartmentsListBox.Items)

{

item.Checked = hc.DepartmentHourCategoryLinks.Any(l => l.DepartmentID == Guid.Parse(item.Value));

}

And the validator:

<asp:RequiredFieldValidator ID="DepartmentsValidator" runat="server" ControlToValidate="DepartmentsListBox" ValidationGroup="Save" CssClass="Validator" Text="*" ErrorMessage="<%$ Resources:Resources, DepartmentsRequiredMessage %>" />

As you can see the DataBound event checks the preselected items as it should, but if I click my validation button I get the error from my validator that I haven't checked any items in the RadListBox.

What am I doing wrong?

Thanks in advance.

Regards,
Datamex

[Solved] Different DataTypes in one Templatecolumn

Hi there,

I have to handel different Datatypes in one Templatecolumn. For this I have to load dynamic different controls to provide a proper interface for the user.
I attached a picture to this post.

As you can see, the column "typ" represents different kinds of datatypes. If the user presses the editbutton, the control in the colum "Wert" has to represent a proper control. For the date-type I need the "raddatepicker" and for the integer a RadNumericTextBox and so on.

Anybody an idea to solve this problem?

Best regards.
