Hi,
I'm brand new to Telerik and I'm feeling kind of stupid.
I have a 2D Stacked Bar Chart

I am trying to refresh the data after a set interval.  I'm creating a dashboard application.
Whenever I refresh the data the new data is just getting added to the old data.
I tried setting the itemsource to nothing but it does not seem to make any difference.

The code I'm using was basically cannibalized from one of the demos and I really don't know what I'm doing.

First off how do I remove the data before adding it again?

Second is there a good place someone can point me to, to learn more about the following objects?
SeriesMapping, DataSeries, ItemMapping, DataPointMember.... I'm having a hard time understanding when to use what.

Thanks in advance and I apologize for my ignorance.

Hi,
I have address types combobox in my RadGridView.
 <telerik:GridViewComboBoxColumn Header="Address Type" Width="100"  Name="AddressTypes" SelectedValueMemberPath="AddressTypeID" DataMemberBinding="{Binding AddressTypeID ,Mode=TwoWay}" DisplayMemberPath="Name"  />

How can I make is eidtable and text complte property etc like in regular combox.
Thanks

Hi
I have a GridView that shows a bunch of rows and has 15 columns, let me name them A1, A2, A3, M1, M2, ...to M12.
Each "M" column can have a value that is either "1" or "0".
I want to show the cell that are "1" with background="Black" and those that are "0" with Background="White".

Following the documentation  I use a class CellTemplateSelector that implement a DataTemplateSelector ( object item, DependencyObject container ).

In the documentation the Template selector is used for formatting one column of the GridView based in its value.So it works for one column in the whole row.

In my case I need to call my CelllTemplateSelector from every "M" column cell in the row and decide what format apply to the cell based on its value (0 or 1).

If I use the Selector implemented in the documentation, I notice that when I call it, I get the parameter "item" that gives me the whole row but I don't know what column I am calling from.

I need to get the column from where I am calling from in order to check for the value of that specific column in order to select the template to apply.

So my question is: How should I call my TemplateSelector and pass the row but also the column name I am calling from.. 

Thanks

Hi there,

I have a RadChart plotting actual and forecast sales against month using a single LineSeriesDefinition.  I would like to change the colour of the forecasted sales numbers, after the current month.  Is that possible?

Many thanks!

After the user clicks and resizes a rad splitter in a docking layout, the splitter is left with keyboard focus.  This is not the case with standard WPF grid splitters and I would like to have a similar behavior in a docking layout. To test: Click and resize a splitter then press the up/dn/left/right arrow keys -- I would like keyboard focus left where it used to be not on the splitter.

Usually in WPF, this means setting Focusable = false. I am setting that on the RadSplitContainers and on RadDocking but it does not help.

Does anyone have a technique for acheiving this?

Hello,

is it possible to overwrite the "Grouped by" text in the groupdescriptor header?
I've found no attribute for changing the text.

I have a simple 3 column GridView.  The 2nd column is defined as a GridViewComboBoxColumn.  I would like to bind an Enum list to that ComboBox.ItemsSource property.  How do I do this?

On a typical combobox, I could do the following:

 

 

 

Thanks for your help.

 

 

 

 

 

 

 

 

Hey all,

Does anyone know how to build a hierarchical TreeView like we have the ability to do in WinForms.

In WinForms I can do:

radTreeView1.DataSource = industryCodeList;
radTreeView1.DisplayMember = "Description";
radTreeView1.ValueMember = "IndustryCode1";
radTreeView1.ParentIDMember = "ParentIndustryCode";

I would then get a hierarchical TreeView that was really simple to use.

Thanks,

Hi,

I have been using DataTables bound to Telerik GridViews for displaying tabular data. But in some I cases I will have to stop using the DataTable and instead use a custom class which simplified would look like this:

Could anyone point me to any resource that explains what I need to add to my classes so that the GridView displays them like it displays a DataTable?

Thanks,
Jose

Hi..
How can I initially set the value to blank   "  /   /   " -
