Telerik chart series tooltip and color

1) Is it possible to change the color of a line chart depending on the value?
e.g If the value is less than a threshold value it is green. Once the line passes the threshold the color should be red.

2) Is it possible to show a tooltip between the PointMarks. My X-axis is time and depending on the hover location i want to show an image on the tooltip.

Thanks

Error trying to group by GridAutoCompleteColumn

When I try to group by a GridAutoCompleteColumn (dragging the column header in the grouping header) I get this error.
Don't know if is a known bug/limitation of that type of column or there is something messed in my implementation.

Dynamic Chart - Legend doesn't update

Hi everyone

I have a HTMLChart that gets populated via the database, based on a drop down.

It works fine, it populates and sets the pie chart, but the legend doesn't update. For example, if the first selection has 2 values, I get two legends, but when I then I get a selection with 4 values, it stays 2 values in the legend? Also, I have set the DataFormatString, but it stays with 4 decimals for the yValue?

<telerik:RadHtmlChart ID="uxPieChart" runat="server">

<PlotArea>

<Series>

<telerik:PieSeries StartAngle="90">

<LabelsAppearance Position="Circle" DataFormatString="{0:C}" />

<TooltipsAppearance DataFormatString="{0:C}" />

</telerik:PieSeries>

</Series>

</PlotArea>

<ChartTitle Text=""/>

</telerik:RadHtmlChart>

uxPieChart.PlotArea.Series.Clear();

int fundID = int.Parse(uxFundList.SelectedValue);

DataTable dt = Fund.BudgetBreakDown(fundID);

PieSeries pieSeries = new PieSeries();

SeriesItem item;

foreach (DataRow budgetRow in dt.Rows)

{

item = new SeriesItem();

item.YValue = Decimal.Parse(budgetRow["Amount"].ToString());

item.Name = budgetRow["Header"].ToString();

pieSeries.Items.Add(item);

}

uxPieChart.PlotArea.Series.Add(pieSeries);

Any ideas?

Thank you

[EDIT] It was due to 0 Values coming through from the DB, you couldn't see it on the chart, but it created a legend. Sorted it out now.

[Solved] get *only* the text that you typed (and that is allowed)

i am trying to get the text that i have typed into my radcombobox.

The combobox is defined as :

cmb = New RadComboBox

cmb.ID = "cmbSearch"

cmb.ShowDropDownOnTextboxClick = False

cmb.MarkFirstMatch = True

cmb.DataTextField = "TextField"

cmb.DataValueField = "ValueField"

cmb.ShowToggleImage = False

' cmb.AutoPostBack = True

cmb.Attributes("onkeyup") = "handleKeyPress();"

If Not Page.IsPostBack Then

cmb.DataSource = _recipe.getAllStockItems(_security.UserID, _security.DivisionId)

ViewState("cmbDataSource") = cmb.DataSource

cmb.DataBind()

End If

Master.Menubar.Add(cmb)

now, every time i type something into the box, the 'handleKeyPress' javascript function runs - as you can see in the above code.

this javascript function is defined as:

function handleKeyPress()

{

var combo = $find('<%=cmb.ClientID%>');

// alrt('error');

document.getElementById('<%=hidAutoComplete.ClientID%>').value = combo._filterText;

document.getElementById('<%=hidAutoComplete.ClientID%>').blur();

// alrt('error');

<%=Page.ClientScript.GetPostBackEventReference(hidAutoComplete, "Change")%>

}

this is almost ok.
The point that is confusing me is that the 'combo._filterText' gives me my text that i have typed, and this would look like it works.
e.g:
the radcombobox has an item 'david'. i type in 'da' and the radcomobobx autocompletes it to 'david' but combo._filtertext gives me 'da'.
this is correct and how i would expect it to work.

now, if i typed 'daa' (which doesn't exist in the combobox), the combobox stops me from adding this extra 'a' and will autocomplete it to 'david'.
this is also correct. unfortunately, and this is the problem, 'combo._filtertext' shows 'daa'.

is it possible to get just 'da'. that is, only the text i have entered, and that i am allowed to enter?
