Show entire grid in multicolumncombobox without scroll bars

I have been searching for a solution to this issue on the forums but so far, have not found anything that makes the MultiColumnComboBox display the entire Gridview component without any scroll bars. That is to say, I do not want the width of the gridview component to be constrained by the width of the combo box itself. I am attaching a small picture of what I am looking for as an attachment (this picture came from the the following link: http://www.telerik.com/help/winforms/gridview-columns-gridviewmulticomboboxcolumn.html and is located at the bottom of the page.) The attachment appears to use radmultiColumnComboBox control inside a grid. I do not know if this makes any difference in the behavior of the combo box.

Any advice on how this can be done?

Thank you for reading my post and any assistance you can offer.

How do I set the initial value for a dropdown?

I have a dropdownlist editor as a column. I have loaded it with the values "", "s", "m"

I have an object that has an "s" stored in it...when I initialize the editor I would like to load the initial value that the object has in it....but I can't get it to work. The value of the cell is always null even after I set it.

Thoughts?

private void rgcSoil_CellEditorInitialized(object sender, GridViewCellEventArgs e)

{

if (e.Column.Name != "colSorM")

return;

RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;

if (editor != null)

{

var ee = (RadDropDownListEditorElement)((RadDropDownListEditor)this.rgcSoil.ActiveEditor).EditorElement;

ee.BeginEdit();

ee.DataSource = new String[] {"", "S", "M" };

SoilType st = (SoilType)e.Row.Tag;

ee.Value = st.StandardOrModified;

ee.EndEdit();

}

2011 Q2 - Drag and drop from ListView to RadTreeView, how to expand the node where the mouse is over?

Hi, i drag and drop from a ListView (MS) to a RadTreeView

But i need a function that if the mouse is while is dragging over a node it should be automaticly expand so that the user can browse the tree where he can drop the item.

How can i archive that?

Here are my codes:

private void listView_Result_ItemDrag(object sender, ItemDragEventArgs e)

{

lblDragID.Text = listView_Result.SelectedItems[0].Tag.ToString();

listView_Result.DoDragDrop(listView_Result.SelectedItems, DragDropEffects.Move);

}

private void TreeHome_DragDrop(object sender, DragEventArgs e)

{

try

{

string x = lblDragID.Text;

Point p = System.Windows.Forms.Control.MousePosition;

// Expand node if the mouse is over a one, and get the node id if the drop is finished (?)

MessageBox.Show(lblDragID.Text);

lblDragID.Text = "0";

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

???

And yea, another small question here :D
How can i expand/open a node with just the id is stored in the tag field?

Thank you for the help

Floating a Tool Window Tabbed Document

Hi,

After realising it was not possible to float Tabbed Documents, I have attempted to use Tool Windows which have a dock state of Tabbed Document. I can now right click on the header tab and select floating, however I cannot drag the window into a floating window as per normal Tool Windows. Is this supported behaviour? If not, is it possible to allow this using the DragDropService?

Cheers,

Steven

AutoHideWindowClosing event?

I have a Raddock that contains a toolwindow that's set to autohide and it's docked on the left. The tool window contains some RadMulticolumnComboBoxes. The window is real wide, but not very tall, kind of like a thin tool strip that slides out with some additional options for the user. The problem is when the window opens, and then you open one of the comboboxes, the bounds of the dropdown box extends past the bounds of the window. So when you select an item, it automatically auto-hides the window since you're clicking 'outside' of it. Is there any way to catch this before it happens and stop the window from auto-hiding (AutoHideWindowClosing?) I don't want the window to automatically hide upon selecting an item from the combobox. Any input is appreciated!

Thanks,
Jason
