[Solved] Multiple Series in one Pie-Chart

Hallo,

I am trying to display multiple series in one Pie-Chart with the following VB-code:

Dim chartSeries As ChartSeries

Dim dataset As GeschlechterverhaeltnisDataTable = GetMyData()

Me.pie_Chart.Chart.Series.RemoveSeries()

Me.pie_Chart.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Font = New Font("Arial", 10)

Me.pie_Chart.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Color = Color.Black

Me.pie_Chart.PlotArea.XAxis.AutoScale = False

Me.pie_Chart.Legend.TextBlock.Appearance.TextProperties.Color = Color.LightSkyBlue

Me.pie_Chart.Legend.Appearance.Position.AlignedPosition = AlignedPositions.Right

For i As Integer = 0 To dataset.Count - 1

chartSeries = New ChartSeries(dataset(i).Column1.ToString(), ChartSeriesType.Pie)

chartSeries.AddItem(New ChartSeriesItem(dataset(i).count_result, dataset(i).count_result))

Me.pie_Chart.Series.Add(chartSeries)

Next

        Me.Chart_GenderRate.AddChartSerie

s(chartSeries)

In the result, i have a number of charts, which are equal to the "dataset.Count - 1" value. but all values should be displayed in one chart like the second chart in the following example: Example

Box Custom ToolTip

Hello guys

How do I get the tooltip box that appears on an outline of the message or image in the tooltip? Below is an example that I used but no box appears, just a background image.

<telerik:RadTextBox ID="RadTextBox" runat="server" Width="196px" Skin="Office2007">
<ClientEvents OnValueChanged="ValueChanged" />
</telerik:RadTextBox>

<telerik:RadToolTip runat="server" ID="RadToolTip2" RelativeTo="Element" Width="390px" Height="70px" TargetControlID="RadTextBox" Animation="Fade" EnableShadow="true" CssClass="tooltip">
<img src="../Imgs/ToolTip.png" alt=" " /
</telerik:RadToolTip>

Please Help - Cell Text in Edit Mode

Hello,

I am manipulating a cell's text by using the Grid_ItemDatabound event. See below:

If TypeOf e.Item Is GridDataItem Then

Dim gridDataItem As GridDataItem = e.Item

Dim quoteID = gridDataItem.Item("quoteID").Text

Dim lineID = gridDataItem.Item("lineID").Text

Select Case gridDataItem.Item("assortmentTypeID").Text

Case 1000

gridDataItem.Item("assortmentTypeID").Text = "Text for 1000"

Case 1002

gridDataItem.Item("assortmentTypeID").Text = "Text for 1002"

Case 1003

gridDataItem.Item("assortmentTypeID").Text = "Text for 1003"

End Select

End If

This works fine until I place the grid in Edit Mode. When I do, the text in the cell defaults back to the value coming from the datasource (1000, 1002, or 1003). The value in this particular cell is ReadOnly, so I am not allowing edit. How can I get the cell text to stay the way I format it regardless of what mode the grid is in? I've tried several combinations of things using the IsInEditMode, GridEditableItem, GridEditFormItem, etc.

Thank you for any help you can offer.

Frustrated,
Jim

Performance Issue with RadGrid and FrozenColumns

Hi,

i have an asp.net application using a radgrid. I want to froze some columns.
Everything works fine, but if I set UseStaticHeaders="true" and FrozenColumnsCount="4" the performance of our application will break down extremly.
Our data volumn is as follows: approximately 330 rows with each 55 columns. We build our grid programmatically in our code behind file.

Could you please give us an answer if it is wise to use FrozeColumns with such an data volumn and szenario? If so, please provide some performance hints.

Here the code of my aspx page:

<telerik:RadGrid ID="GridProjectProposals" runat="server" AutoGenerateColumns="false" AllowSorting="true" Height="650px" Width="1200px" GridLines="None" Skin="Windows7" AllowMultiRowSelection="True" AllowFilteringByColumn="True">

<ClientSettings EnableRowHoverStyle="true">

<Selecting AllowRowSelect="true" EnableDragToSelectRows="true" />

<Scrolling AllowScroll="true" EnableVirtualScrollPaging="true" SaveScrollPosition="true" UseStaticHeaders="true" FrozenColumnsCount="4" />

</ClientSettings>

<MasterTableView GridLines="None" AllowNaturalSort="true" EditMode="InPlace" AllowMultiColumnSorting="true">

<Columns>

</Columns>

<HeaderStyle Width="180px" />

</MasterTableView>

</telerik:RadGrid>

Looking forward to get some ideas and your input.

Thanks ...

Loading Panel not transparent with IE9 and new Telerik version

Hello,

I currently updated our Telerik libraries to the latest version (2011.1.315.35) to be accessible to IE9. However, when performing AJAX operations in IE9, the loading panel on the control is not transparent; i.e. in the loading image, with a pure white background, is the only thing visible.
Is this replicable or is this just my browser?

Thanks,
Ernest

RadTreeList - Pagging Issue

Hello Telerik Team,

We have a problem using TreeListView. Because there are a lot of records as result, we need to use paging in db. First page is displayed ok, but when another page is selected, this error is thrown: “the table must contain row sections in order of header, body, then footer”. VirtualCount is not supported for this control.

See below the definition of the treelist:

<telerik:RadTreeList ID="rtlDescendants" runat="server" ShowTreeLines="true" ShowOuterBorders="true"

ParentDataKeyNames="ParentInstanceID" DataKeyNames="InstanceID" AutoGenerateColumns="false"

Skin="Office2007" OnNeedDataSource="rtlDescendants_NeedDataSource" OnItemDataBound="rtl_ItemDataBound"

AllowPaging="true" AllowSorting="false" PageSize="10" onpageindexchanged="rtlDescendants_PageIndexChanged">

<telerik:TreeListTemplateColumn HeaderText="ID">

<asp:Image ID="imgDomain" Width="16px" Height="16px" ImageUrl='<%# String.Format("~/images/Metallic16x16/{0}16x16.png", Eval("DomainName").ToString().ToUpper()) %>'

runat="server" /> 

<asp:LinkButton ID="lnkName" runat="server" CausesValidation="false" Text='<%# Eval("Name")%>'

PostBackUrl='<%# String.Format("~/CI/Attributes.aspx?InstanceID={0}", Eval("InstanceID")) %>'></asp:LinkButton>

</ItemTemplate>

</telerik:TreeListTemplateColumn>

<telerik:TreeListTemplateColumn HeaderStyle-Width="3%" ItemStyle-Width="3%" ItemStyle-HorizontalAlign="Center">

<asp:ImageButton ID="imgbPreview" runat="server" CausesValidation="false" OnClientClick='<%# String.Format("OpenPreviewPanel({0})", Eval("InstanceID")) %>'
