Insert w/Binding List

I am using a Binding List to store some data.
I attach it to the the grid via DataSource.
Data displays properly.
However, when I click on add new row and enter in some data, I can't get the data to persist in my collection.
Do I need to wire up an event and handle this on my own? or am I doing something else wrong?

Thanks,
Eric

Collapse QuickToolbar Items

Is there a way, using Q4 2006 to collapse the whole QuickAccessToolbar or items within it? Apparently the properties of items within the menu can not have the visibility property set to Collapse like the chunks. The hide would work except it doesnt actually hide the item, it leave a blank space where it would go and it still is available on the drop down arrow at the end of the toolbar. Here is the example I am trying to accomplish:

Making a developer tool which needs to log in to a database. Once logged in I will show all the necessary ribbon chunks which contain tools. I also want a Disconnect button. The orb menu is a good place but I do not like the way it looks compared to the chunks so I want it on the QuickAccessToolbar. I can not show or hide the Disconnect button based on the users status.

Any suggestions?

state change appearance of tabs and menu items

I am using the menu and the tab controls in my windows application.

I like the appearance of an existing theme (Control Default), but I want to change the way the control appears during state changes. Specifically:

1. I do not want state changes of mouse over to affect the tab or menu controls
2. I only want the background color and font style to be affected when the tab is the currently selected (visible) tab.

The states that seem to be associated with the tab control are:
(!IsMouseOver and !IsSelected)
(IsMouseOver and !IsSelected)
(IsSelected and IsMouseOver)
(IsSelected and !IsMouseOver)
(InitialState)

I have made some attempts to make changes, but so far they have not had the desired effect.

Can you please tell me what states I should use for the behavior I am looking for, and which elements I need to assign these states to?

Thanks very much!

Editing/filtering on RadGrid Crash the application, with System.Argument null exception

I am trying to use the RadDataGrid view, with the autoGenerateColumn Property set to false, I added three columns as follows.

radGridView1.Columns.Add(new
Telerik.WinControls.UI.GridViewDataColumn("ProductId"));
radGridView1.Columns.Add(new Telerik.WinControls.UI.GridViewDataColumn("ProductName"));
radGridView1.Columns.Add(new Telerik.WinControls.UI.GridViewDataColumn("UnitPrice"));

and then i bounded the data source to list<Products>

When I run the application and try to edit any of the fields or if I try to type in the filter box the application crashes with the following exception. While investigating the problem I found out that the default editor for the columns is never instantiated and is set to null

radGridView1.Columns["ProductId"].GetDefaultEditor()==null

Sample Code
-----------

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

radGridView1.MasterGridViewTemplate.AutoGenerateColumns = false; //disable auto generate columns

radGridView1.EnableFiltering = true; //enable filter

radGridView1.MasterGridViewTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;

//Add columns

radGridView1.Columns.Add(new Telerik.WinControls.UI.GridViewDataColumn("ProductId"));

radGridView1.Columns.Add(new Telerik.WinControls.UI.GridViewDataColumn("ProductName"));

radGridView1.Columns.Add(new Telerik.WinControls.UI.GridViewDataColumn("UnitPrice"));

//Bind data

radGridView1.DataSource = GetProductList();

}

public List<Product> GetProductList()

{

var products = new List<Product>();

products.Add(new Product("PRD-001", "Betty Crocker® Angel Food Cake Mix", 8.65));

products.Add(new Product("PRD-002", "Betty Crocker Complete Desserts®", 8));

products.Add(new Product("PRD-003", "Betty Crocker® Cookie Mix", 1.25));

products.Add(new Product("PRD-004", "Betty Crocker® Frosting", 4.00));

products.Add(new Product("PRD-005", "Betty Crocker® Sunkist® Lemon Bars", 10.00));

products.Add(new Product("PRD-006", "Betty Crocker® Supreme Brownie Mix", 2.00));

products.Add(new Product("PRD-007", "Betty Crocker® Variety Dessert Mixes", 3.55));

products.Add(new Product("PRD-008", "Betty Crocker® Warm Delights® Desserts", 4.49));

return products;

}

public class Product

{

public Product()

{

}

public Product(string id, string name, double price)

{

this.ProductId = id;

this.ProductName = name;

this.UnitPrice = price;

}

public string ProductId { get; set; }

public string ProductName { get; set; }

public double UnitPrice { get; set; }

}

Office2007BlackTheme Control in Q2 2008 release

Hi,

I am attempting to apply the Office2007BlackTheme from the Q2 2008 toolbox with no luck.

I can't find any information in the documentation on how to set my RadForm to this theme. In Q1 the theme was available straight from the ThemeName property on the form.

Thanks

Charles

Concepts Documentation

We are evaluating rad controls. In the examples I noticed a property on the grid called "EnableHotTracking". I am looking around for an explanation of that property. But I couldn't find in the documentation other than the MSDN style help documentation which doesn't say nothing about that property.

Is there any detailed documentation that helps to reduce the learning curve on using these controls?

Theming subitems

Hi,
i have created a Custom control from RadControl.
It has items (following the magnify example) but when theming:
a) the control dissapears when opening themebuilder (very strange)
b) all the subitems (no matter what type they are) gets the same theme as the parent (if the parent is themed as a button, all subitems gets this theme, even if they are radimages or checkboxes)..
Is there any way to create a custom theme item for this elements (they don't have the themename property) so i can give them a diferent look as the father?
Thanks in advance!

AutoScroll and Subitems

Hi,
i'm creating a custom control (following the magnify demo), but even when the "autoscroll" property is set, it does nothing for RadItems inside the container, only for "external" controls i placed over the control.
Is there any way to activate the scroll for this items created by the control itself?
Thanks in advance..
