Using predefined images as fill for bar charts

While using the now obsolete ChartView I was able to use custom image files in .png format, (similar, but different from the currently offered GradientStyles) as a filler for my bars in BarCharts. I used:

Series[0].Items[0].Appearance.FillStyle

which had several useful Properties.

What would be the corresponding code using RadChartView to use these same images?

Thanks,
Rob

display grid summary row in report generated from RadGridView (Winforms)

Hi,

I'm trying to export RadGridView data to a teleric report. I found the RadGridReportingLite sample project on the teleric website and have been playing around with it. My question for anyone of you that have used it or designed it is - can i tweak the radgridReport class to include items in the gridSummaryRow collection or do i need to add a custom row to my grid which will perform aggregation ?

Thanks in advance
Anisha

[Solved] Visual Designer for ColumnGroupsViewDefinition

Is there any way to build and assign a ColumnGroupsViewDefinition visually in a designer or can this only be achieved programmatically?

I am using a RadGridView with ViewDefinition of type ColumnGroupsViewDefinition to achieve column grouping (Q1 2010 release). I am able to programmatically build a ColumnGroupsViewDefinition and assign it to the RadGridView.ViewDefinition property and its working fine but I was just wondering if this can be accomplished in the Designer.

Thanks for your help,
Darren Shafer

Design Time Column Types for Bound Grid

When you bind the GridView to a data source at design time, the columns get auto generated - it creates a new Project Data Source from an Object and generates a form BindingSource.

However, on the object I have a reference to another object - ClassA -> ClassB Property which references a ClassB instance.

At design time, a TextBox column is generated. Where as at runtime, I need this to be a DropDown list. Is it possible to change the column type at design time or make it generate a DropDown for the object reference property - without creating an Unbound Column?

Thanks

[Solved] Switching a row's DataSource on a GridViewComboBoxColumn

I'm trying to swap out the datasource on a ComboBoxColumn depending on other data bound to the row. Below is a simple example to reproduce the problem. (In my actual project we are not using simple strings for the options)

In this example the second row's combo box should have a 3rd option not shown by the first row.
If I let the grid automatically generate columns instead of adding it manually it seems to work correctly. What am I doing wrong?

public class SimpleObject

{

public string Option { get; set; }

public bool ShowOtherOptions { get; set; }

public SimpleObject (string option)

{

Option = option;

}

Relevant code behind for the form:

private List<String> options = new List<String>(){"First", "Second"};

private List<String> specialoptions = new List<String>(){ "First", "Second", "Third"};

public SimpleSample ()

{

List<SimpleObject> myList = new List<SimpleObject> ();

myList.Add (new SimpleObject ("First"));

myList.Add (new SimpleObject ("Second") {ShowOtherOptions = true});

InitializeComponent ();

this.radGridView1.AutoGenerateColumns = false;

AddComboColoumn ();

radGridView1.DataSource = myList;

radGridView1.EditorRequired += radGridView1_EditorRequired;

}

private void AddComboColoumn()

{

GridViewComboBoxColumn comboColumn = new GridViewComboBoxColumn("ComboBox column");

comboColumn.Width = 150;

comboColumn.FieldName = "Option";

comboColumn.DataSource = options;

radGridView1.Columns.Add(comboColumn);

}

private void radGridView1_EditorRequired (object sender, Telerik.WinControls.UI.EditorRequiredEventArgs e)

{

if (radGridView1.CurrentColumn.Name == "Option")

{

var data =

(((Telerik.WinControls.UI.GridViewEditManager) (sender)).GridViewElement.CurrentRow).DataBoundItem

as SimpleObject;

RadDropDownListEditor dropdownEditor = new RadDropDownListEditor ();

if (data.ShowOtherOptions)

{

((RadDropDownListEditorElement) (dropdownEditor.EditorElement)).DataSource = specialoptions;

}

else

{

((RadDropDownListEditorElement) (dropdownEditor.EditorElement)).DataSource = options;

}

dropdownEditor.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

e.Editor = dropdownEditor;

}
