                    {  
        
                        SchedulerMonthViewElement monthView = this.schRates.SchedulerElement.ViewElement as SchedulerMonthViewElement;  
        
                        Telerik.WinControls.RadElementCollection childrenCollection = monthView.Children[1].Children;  
        
                        foreach (MonthCellElement cell in childrenCollection)  
        
                        {

Adding Rows to Grid Programmatically

I have a grid that contains a dropdown column as bellow:

GridViewComboBoxColumn type = new GridViewComboBoxColumn();

type.Name = "Type";

type.HeaderText = "Type";

type.ValueMember = "Id";

type.DisplayMember = "Type";

type.DataSource = new string[] {"A", "B", "C"};

type.DropDownStyle = RadDropDownStyle.DropDownList;

grid.Columns.Add(type);

Suppose the user adds two new rows and selects "A" from dropdown for the first row and selects "B" from dropdown for the second row. I don't know how I can save the grid and then load it later. I should say that I know how to use Linq to save data into SQL database, but I don't know how I can get the values that the user selected and how to load data into grid later. Please help me.

Custom Autocomplete on Editor

Hello Telerik

I would like to have an editor in a GridView for selecting one business object (DataBase Key, Name, Code (like an EAN CODE) in a collection. As The name is also considered to be an unique Key, the editor is based on a textbox which display the name of a product. The textbox should have a autocomplete feature (suggest with a dropdown) but the suggestion should be based on the whole list of product filtered by the Name or the Code.

The editor is valid only if the text is matching a product name (return the matching DataBase key for the binding) or is empty (return a nullvalue for binding).

What is the best way to reach this objectif ? Should I start from a RadDropDownListEditor, a RadTextBoxControlEditor, a RadTextBoxEditor ?

Thanks for your support

RadListControl Crashes VS2010 Designer

Here is the problem I am having:

1. I created a simple RadForm called form1.cs and added a number of labels, panels and text boxes to it. I run this form and everything is good.

2. I created a second RadForm called form2.cs and it extends form1.cs. I run this form and everything works fine.

3. I add a RadListControl to form2. I run this and the designer view of the form disappears, the program runs, when I exit the program I get an error stating "The designer loader did not provide a root component but has not indicated why." and the designer view is gone.

4. I close form2.cs, rebuild the project and open form2.cs and it appears in the designer. As soon as I make any code changes to form2.cs (even as simple as moving the locaiton of a control by one pixel), save and run the file I get the same error listed in step 3.

This only has happened to me with the RadListControl. textboxes, labels, panels, manu bars, status bars, etc. do not exhibit this behavior.

I have a full solution I can provide that causes the problem. Tried to open a support ticket but there is no option for the ListControl. Let me know what I should try next.

BTW, Computer is HP laptop, Windows 7, latest winForms release (Q2 SP1 build 806), VS 2010 Ultimate. I believe everyting Microsoft is at latest patch level.

Mnemonic activated without Alt key

When I press a key inside a grid, a mnemonic outside the grid is activated, instead of the grid entering edit mode.
For instance, with a combo box column, I expect the first item starting with the key pressed to be selected.

To reproduce, add a grid view, and standard win forms button to a form. Add the following code to the form:

public Form1()

{

InitializeComponent();

var list = new List<Data>();

list.Add(new Data(1, "Apple"));

list.Add(new Data(2, "Banana"));

list.Add(new Data(3, "Orange"));

var lookupList = list.ToList();

radGridView1.MasterTemplate.AllowAddNewRow = false;

radGridView1.MasterTemplate.AllowColumnChooser = false;

radGridView1.MasterTemplate.AllowDeleteRow = false;

radGridView1.MasterTemplate.AllowDragToGroup = false;

radGridView1.MasterTemplate.EnableGrouping = false;

radGridView1.ShowGroupPanel = false;

radGridView1.Columns.Add(new GridViewComboBoxColumn("Key") { DataSource = lookupList, ValueMember = "Key", DisplayMember = "Value" });

radGridView1.Columns.Add(new GridViewTextBoxColumn("Value"));

radGridView1.DataSource = list;

button1.Text = "&Button";

button1.Click += button1_Click;

}

private void button1_Click(object sender, EventArgs e)

{

RadMessageBox.Show(this, "Button Pressed");

}

Add the following class:

public class Data

{

public Data(int key, string value)

{

Key = key;

Value = value;

}

public int Key { get; set; }

public string Value { get; set; }

}

Click on a combo box cell and type "b". The button is activated, instead of selecting Banana in the combo.

Is this a bug?
Is there a work around?

Setting backcolor, gradient, etc. in code

I want to be able to set the backcolor for the chart itself with a gradient. I can easily set the backcolor property but don't see away to control the gradient. I see that in the property build under Edit UI Elements there is the RadChartElement. Not sure how to get to that programmatically? Please advise or let me know the correct way to accomplish this.

Thanks

Add Current Selection to Filter

In Microsoft Excel there is an option named Add Current Selection to Filter. Actually, in Excel, when you search a key in filter popup and click OK, then when you search another key in filter popup then there is an option named 'Add Current Selection to Filter'. I need something like this option in radGridView Excel Like Filtering. Please see the attached file.
