Noticed an issue with the autocomplete functionality in regards to the DropDownList not selecting the item when the control loses focus when in SuppestAppend' mode. In an older Demo for the ComboBox you type the letter 'U' and 'USA' is selected and when you tab off the Index and Text fields are populated on the right hand side. In the latest demo for the DropDownList you type the letter 'U' and 'USA' is NOT selected and when you tab off the Index and Text fields are NOT populated on the right hand side plus the drop down portion of the control does not disappear. Also if the drop down portion is already displayed when a letter is first pressed, then the full list stays whilat a new list appaers with the suggested items.

Button Link

Hello,

I have a grid with dynamic columns, and for certain columns I need a button link that allows navigation to the master record related with the value (buttonlink.jpg).

For example, if colums show "Customer code", left to the customer code an arrow allows to open the form "Customer" and shows all the information related with such code.

This is the code to show the button:

Private Sub gridSELECT_CellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) _

Handles gridSELECT.CellFormatting

e.CellElement.Image = Nothing

If e.CellElement.ColumnInfo.Name = "CardCode" AndAlso TypeOf e.CellElement.RowInfo Is GridViewDataRowInfo Then

e.CellElement.ImageAlignment = ContentAlignment.MiddleLeft

e.CellElement.Image = My.Resources.arrow_right

e.CellElement.TextImageRelation = TextImageRelation.ImageBeforeText

End If

End Sub

How can I do to catch the click in this button? Is it possible?

Capture text from combobox

Hi.

My interpretation of a combo box is, that one can either select an element from a predefined list - or just enter a value directly.

However, the GridViewComboBoxColumn seems not to work this way. I do have:

RadDropDownListEditor le = (RadDropDownListEditor)this.MasterTemplate.ActiveEditor;

RadDropDownListEditorElement ee = (RadDropDownListEditorElement)le.EditorElement;

le.DropDownStyle =

RadDropDownStyle.DropDown;

ee.AutoCompleteMode =

AutoCompleteMode.None;

But whatever entered directly in the combo box disappears when I move to next column.

Is there a way to meet my expectations so if the user enters data directly, it'd be considered text and applied to the field when the editor closes.

I need this behaviour cause sometimes data has to be selected from a list - and sometimes they should be entered directly...

Line numbers for tree nodes

I'm planning to use the treeview as an alternative for the listview component for displaying multiple lines that can:

- indent
- selected via checkbox
- drag/drop
- image per line (node)
- collapse/group lines

All can be done with the treeview. The only thing I have on my "wishlist" is a way to number the "lines" (= nodes). Is it possible to add lines numbers to the left of the notes, just like f.e. in a code editor (all aligned on the left before the nodes)?

I am using Telerik Version 2009.2.9.701. and Using Telerik.WinControls.Docking.DockingManager in my Form. I am using DockPanel. when user start drag and Drop. I want to prevent user from dropping to Fill DockPosition.

In new version, offers DragDropService which has AllowedDockManagerEdges and PreviewDockPosition to achive this funcnality. But, at this point I can not update the my Telerik Version to new one.so, I have restriction to use only 2009.2.9.701.

Please suggest any solution or workaround that is avilable in 2009.2.9.701 Version in Telerik.WinControl.Docking.dll.

Help would be appriciated.

Thanks.

Drag 'n drop databound

Hi all,

Due to the current lack of support of the RadtreeView for automatic drag and drop when the control is databound, to I am trying to "roll my own". However, I got stuck on a few things, so I really hope someone can help me out.

I have subclassed the RadTreeView, RadTreeViewElement and TreeViewDragDropService classes and am implementing my own versions of OnDragEnter and OnDragDrop. I am assuming that the DragDrop event is the one that I need to override in order to find out on which node the dragged one is dropped.

I can easily find out what node is being dragged by using the value returned in the Data object as below:

drgevent.Data.GetData(typeof(RadTreeNode))

That works fine. However, I am failing to (1) find out what node it is dropped on and (2) what the databound item is for that node. When I use:

var targetNode = this.GetNodeAt(drgevent.X, drgevent.Y)

it always returns null, and I don't see any method or property that returns the item a node is bound to. I was hoping for something similar to the one in the DataGridView (row.DataBoundItem). Is there anything like that, and what do i do to get the node that the dragged item is dropped on?

Thanks in advance (I have been tearing my hair out about this for far too long).

Lucien.

Keyboard Delay Too Short

Hi. We're running the 2011.1.11.419 version of this control in our product. Our users have pointed out that the keyboard delat that allows you to jump to longer selections has gotten much smaller. So if you have a dropdown with "Bart", "Bob", and "Olaf", you have to type "bo" very quickly to get to Bob, otherwise your selection ends up on "Olaf". I hope this makes sense... I have no idea what you correctly call this feature.

I tried this on the Winforms RadControls demo app, and I had exactly the same result. The maximum delay you can have between typing the "B" and the "o" seems to be 500ms or less, when I'm sure it used to be 1000ms or more.

For our users this is quite a nuisance, since most of them type with two fingers but need to move quickly through dropdowns with hundreds of options. (On the upside... they're learning to type faster :)

Please let me know if you think this is an issue that has appeared in version 2011 / 419 or not. Thanks.

How to use stretch RadComboBox in RadGridView's cell

Hi Telerik's support.
I'm trying to use radComboBox inside radGridView. I made my custom Column and Cell types. As was stated in the article from your site I'm using following code:

txtInput.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

txtInput.RootElement.StretchVertically = true;

txtInput.RootElement.StretchHorizontally = true;

txtInput.TextChanged += TxtInputTextChanged;

Children.Add(txtInput.RootElement);

This code works well in case if instead of ComboBox there will be RadTextBox and TextElement. The problem is RadComboBox has fixed size and doesn't stretch when the size of cell is changed.
