At you on a forum found an example how to make grouping in a combo which is in date grid.
Applying this method a couple of questions arose.
1) Mouse scrolling does not work.
2) How to make AutoCompleteMode

private void UpdateComboBoxSpeziolist()

{

var commandServer = new CommandServer();

_radSpeziolist.SelectedItemChanged += new EventHandler(lv_SelectedItemChanged);

_radSpeziolist.DisplayMember = "fio";

_radSpeziolist.ValueMember = "fio";

_radSpeziolist.DataSource = commandServer.GetDataGridSet(@"select *

from spezialistSurvey()").Tables[0];

_radSpeziolist.EnableGrouping = true;

_radSpeziolist.ShowGroups = true;

GroupDescriptor group = new GroupDescriptor(new SortDescriptor[] { new SortDescriptor("cat", ListSortDirection.Descending) });

_radSpeziolist.GroupDescriptors.Add(group);

_radSpeziolist.AllowEdit = true;

_radSpeziolist.CollapseAll();

}

private void radGridView2_CellEditorInitialized(object sender, GridViewCellEventArgs e)

{

if(e.ActiveEditor is RadDropDownListEditor)

{

RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;

RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;

element.DropDownSizingMode = SizingMode.UpDownAndRightBottom;

element.Popup.Controls.Add(_radSpeziolist);

element.DropDownMinSize = new Size(300, 300);

element.PopupOpening += new CancelEventHandler(element_PopupOpening);

}

void element_PopupOpening(object sender, CancelEventArgs e)

{

_radSpeziolist.Size = ((RadDropDownListEditorElement)sender).Popup.Size;

_radSpeziolist.AutoScroll = true;

}

private void lv_SelectedItemChanged(object sender, EventArgs e)

{

ListViewItemEventArgs args = (ListViewItemEventArgs)e;

if (args.Item != null && radGridViewSurvey.CurrentCell != null)

{

this.radGridViewSurvey.CurrentCell.Value = args.Item.Value;

((DropDownPopupForm)args.ListViewElement.ElementTree.Control.Parent).ClosePopup(RadPopupCloseReason.Mouse);

radGridViewSurvey.CancelEdit();

}

RadGridView filter using wildcards

Hi,

I'm trying to use FilterDescriptors.Expression in radgrid, but everytime i put any wildcard here, it always wraps that wildcard into brackets (name like 'a%' became name like 'a[%]') and grid gets fully filtered, because there is no matching line. I've tried diferent types of wildcards (*, %, ?) but it always gets me the same result. Am I missing something?

Thanks

RadDropDownList: Key event(s) for AutoCompleteSuggest

I can't seem to find any working key events for RadDropDownList.DropDownListElement.AutoCompleteSuggest.

What's currently happening:

A user navigates to the desired auto complete suggestion and presses enter on it. They then have to press enter again(to trigger the RadDropDownList.KeyDown event).

What I'd like to happen

A user navigates to the desired auto complete suggestion and presses enter on it. I'm looking for what this event is.

Thanks,

Brandon

Show empty group expander image for rows without children rows

I have a hierarchical (rows + children rows) RadGridView. I'm already using the ViewCellFormatting event in order to display my own [+] and [-] images.

Is there a way to know if a "parent" row has no children rows the event handler, so I can set an empty image in the first place? That way the user has a visual clue that the row doesn't need to be expanded.

RadDropDownList focus bug

Hi,

I found a bug when adding a few input controls like textboxes etc on a form, in combination with the raddropdownlist (DropDownStyle = DropDownList). When pressing the tab key to focus the next control, everything works normally with the textboxes, but when the dropdownlist gets focus, there is no visual feedback to see which control has the focus. After manually clicking the dropdownlist, the tab key focus works as it should do.

Tested with the winforms product, version 2013.1 321 (mar. 21, 2013) on a Windows 7 machine 64 bit, with the VisualStudio2012Light theme.

PS, I wanted to add this bug in your tracking system, but the RadDropDownList is not in the selection where you should choose the bug-related control. This list could also be sorted alphabetically, which makes finding the right control much easier ;)

Check node exist in treeview

Hello,

i am having a treeview. and adding the nodes manually.

For Each ct In ChecklistTemplate

newChecklistTypeNode = New RadTreeNode(ct.ChecklistTypeName, False)

newChecklistTypeNode.Tag = ct.CheckistTypeID

newChecklistTypeNode.LoadedOnDemand = True

If (Not tvChecklists.Nodes.Contains(newChecklistTypeNode)) Then

tvChecklists.Nodes.Add(newChecklistTypeNode)

End If

Next

i am checking whether the node is already present in the treeview.
suppose following nodes are already added in treeview
1. abc
2. xyz
3. pqr

if i now add xyz node in treeview the condition tvChecklists.Nodes.Contains(newChecklistTypeNode) returns FALSE.

Please suggest.

Thanks

Diagram Image Zoombox

Hello,

I am trying to create an image reviewer where an image is displayed and reviewed. Right now the image is displayed in a radDiagram as a radDiagramShape.

What I am trying to do is create a feature where a box can be moved over the original image and the portion of the image that the box is over be displayed in a separate shape object. That way the user can have a "zoomed" look over the original image without needing to zoom and pan over the original image.

Can this be done?

Thanks for any suggestions!

Is there a way to keep RadTreeview updated when user manipulates file in Windows Explorer?

I have a RadTreeView that has nodes listing directories and files from a certain location in the file system. Now if I were to go into Windows Explorer and manipulate one of the files, how can I update the RadTreeView automicatically to the user's action? Say if I were to delete the file, how can I refresh the RadTreeView to show that once they do it from Windows Explorer? Is there a way?
