How to get PointMarks to show on a line graph

When the complaint came in that my line graph didn't have visible points at the values, I thought it would be an easy fix.

Somehow, I can't seem to make it happen.

The meat of the code is here:

'Create a series

Dim oSeries As Telerik.Charting.ChartSeries = New Telerik.Charting.ChartSeries()

radChart.Series.Add(oSeries)

'make it a line

oSeries.Type = ChartSeriesType.Line

radChart.Series(0).Appearance.FillStyle.MainColor = Color.Red



'add some data

radChart.Series(0).AddItem(3.5)

radChart.Series(0).AddItem(4.5)

radChart.Series(0).AddItem(6.5)

radChart.Series(0).AddItem(8.5)



' try everything and anything to get the points to show up

radChart.Series(0).Appearance.PointMark.Visible = True

radChart.Series(0).Appearance.PointMark.Dimensions.AutoSize = False

radChart.Series(0).Appearance.PointMark.Dimensions.Width.Value = 20

radChart.Series(0).Appearance.PointMark.Dimensions.Height.Value = 20

radChart.Series(0).Appearance.PointMark.FillStyle.FillType = Styles.FillType.Solid

radChart.Series(0).Appearance.PointMark.Figure = Styles.DefaultFigures.Diamond

I'm using the 4.1.6 version of the dll date 3/10/09

I've been searching the Forum for a mention of a similar problem - how bad is your problem when nobody on the internet has ever had it before?

I've attached a jpg of the output.

Please let me know what add't information would be helpful.

Thank you in advance for the help.

Filtering a GridTemplateColumn with Multiple Checkboxes

I'm trying to figure out how to implement a filter on a template column that has multiple checkbox values.

Scenario
The data source that I'm using for my grid control is an ObjectDataSource that is returning a list of business account objects. This particular column represents a List<> of cost categories objects (contains a name field and boolean isUsed property) that the business account can be used for. The customer wants all available cost categories displayed as check boxes with the ones associated to the current business account to be checked. They want to be able to filter this column by selecting one cost category names from a drop down and it to filter the rows to only those that have that cost category checked.

The code below is from the current page (I removed industry specific terms for the sake of clarity). The selected cost categories are being correctly checked during the ItemDataBound and the filter template is being displayed correctly. However, when I select a value I'm getting the error message following the code.

Code

<telerik:GridTemplateColumn FilterControlAltText="Filter AccountCostCategory column"

HeaderText="Cost Category" UniqueName="AccountCostCategory">

<ItemTemplate>

<asp:CheckBox ID="chkAccountCostCategory_CC1" runat="server" Text="Cost Category 1" />

<asp:CheckBox ID="chkAccountCostCategory_CC2" runat="server" Text="Cost Category 2" />

<asp:CheckBox ID="chkAccountCostCategory_CC3" runat="server" Text="Cost Category 3" />

<asp:CheckBox ID="chkAccountCostCategory_CC4" runat="server" Text="Cost Category 4" />

</ItemTemplate>

<FilterTemplate>

<telerik:RadComboBox ID="ddlAccountCostCategoryFilter" SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("AccountCostCategory").CurrentFilterValue %>'

runat="server" OnClientSelectedIndexChanged="AccountCostCategoryFilterChanged">

<Items>

<telerik:RadComboBoxItem Text="All" />

<telerik:RadComboBoxItem Text="Cost Category 1" Value="CC1" />

<telerik:RadComboBoxItem Text="Cost Category 2" Value="CC2" />

<telerik:RadComboBoxItem Text="Cost Category 3" Value="CC3" />

<telerik:RadComboBoxItem Text="Cost Category 4" Value="CC4" />

</Items>

</telerik:RadComboBox>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function AccountCostCategoryFilterChanged(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

tableView.filter("AccountCostCategory", args.get_item().get_value(), Telerik.Web.UI.GridFilterFunction.EqualTo);

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

<ItemStyle Width="120px" BackColor="#FDE9D9" />

</telerik:GridTemplateColumn>

Argh! Where is the Full Xml Schema for RadMenu?

Hello!

Sure - I can define my own xpath, datavalues etc..but there must be a DEFAULT xml schema setup for this control?

Please..someone tell me where I can get the FULL xml schema definition for RadMenu.
This demo is pathetic - sorry...but it is.

http://demos.telerik.com/aspnet-ajax/menu/examples/programming/xmldefinition/defaultcs.aspx

It states you can use the RadMenu.GetXml() method - but that method does NOT output all of the menu attributes as I'd expect..like url, flow, enabled..

Thanks!
