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

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;

}

SplitContainer in Splitpanel Question

Hi,

i have a RadSplitContainer (Container1) with two SplitPanels Inside.

In the first SplitPanel i have another RadSplitContainer(Container2) with two SplitPanels, the second one should show my information.
The first SplitPanel in Container2 has a RadTreeView inside for my menu.
The second SplitPanel in Container2 has a Button to Collapse the first SplitPanel in Container2

Now the behaviour is that, the first SplitPanel in Container2 is collapsed and the second SplitPanel in Container2 grows to the widht of the first SplitPanel in Container1.
What i want is, that the second SplitPanel in Container1 grows the width of the first SplitPanel in Container2.

Of Course if i press the button while the first SplitPanel in Container2 is collapsed, it should show the first SplitPanel in Container2 again and resize back.

I've added three pictures:
The Start.png is the application started
The Stop.png is the behaviour at the moment
The Wanted.png is the behaviour i want to have, if i press the button (Just moved the Slider by Hand)

Thx

P.S. If i use the Standard SplitContainer from WinForms i have a Property SplitterDistance, if i change this value i get the wanted behaviour, but changing to Standard WinForms Control is no option in my case

Ribbon Context Tab Appearence, Behavior

Hi,

I am liking the Ribbon control at present.

However, I want it to behave and look exactly like the offerings in Word.

I have created 5 Ribbon Tabs in the Designer. Each tab has been assigned to a Context tab.
So I have:
Project tab -> Project Context tab
Contract tab -> Contract Context tab
...and so on.

I can make the contexts appear when I want using:

this.RibbonContextTabProject.Visibility = (entity is AttestedDev.Wms.EFDAL.Entity.Project) ? ElementVisibility.Visible : ElementVisibility.Hidden;

When the tabs are displayed they keep their positions in the Tab order. See attached.

You can see in #1 the Project tab is displayed in its designed position.
You can see in #2 the Contract tab is displayed in its designed position - which is to the right of Project.
You can see in #3 the Drawing tab is displayed in its designed position - which is to the right of Contract.

What I want is the Context tabs to appear in the same position. Like Word 2013 for example - which will append the Context Tabs at the end of the current tabs - see #4 and #5 in attached.

The other issue is that the context tabs are pretty narrow. I would like to have some additional padding on this, but the Padding on the Context tab does not force the width of the tab to be wider. It looks pretty thin.

Can you show me how I can get it to work like this?

Many thanks,

Andez

Custom item elements not working with scroll bars

Hi,

in one of my projects I use the code you described in your "Rad Property Grid Custom Item Elements" project here. This works fine as long as you do not have a scollbar in your property grid and move it. Attached you will find a fiew screen shots which show the problem: The button is moving from one property to another. During debugging I found out that the CreateItemElement event was only fired sometimes.

I am using UI for WinForms Q2 2014. Any help would be appreciated.

Thanks in advance,
Thilo
