Please refer to the picture to see the following information:
T1, T2 are two common cells and T3 is a merged cell
When the mouse moves on T3, it triggers the border of T1 and T2, which will change the cell size of T1 and T2

Vertical alignment problem with mixed fonts

I'm evaluating the RichTextEditor for WinForms as a replacement for another third-party control. Frankly it would save me a lot of work if we could use your control, so I'm very enthusiastic about it, but I've discovered a problem. When a line contains multiple font styles, I'm seeing a vertical alignment issue. Likely no one would ever do this in the real world, but it's part of our regression tests and I know it's going to be a barrier selling this to my boss.

I've attached a couple images. My test app is little more than the editor and an associated ribbon bar, and I used the ribbon bar to make the formatting changes as shown. The default font in Verdana, and the misaligned text is Courier New. I saved the text as a docx and loaded it in Word, and you can see in the other image that the alignment problem is not present.

Any suggestions?

Programmatic filtering

Hi, I'm stuck with such a problem.

I need to filter data at grid only from code (ShowFilteringRow = false). My filter condition is slightly complex so I use the FilterPredicate just like that - https://docs.telerik.com/devtools/winforms/gridview/filtering/custom-filtering#implementing-filtering-mechanism-using-filterpredicate

I've set EnableCustomFiltering = true and implement the PerformFiltering predicate:

private void ChangeFilter(bool filtering)

{

tree.BeginEdit();

if (filtering)

{

tree.MasterTemplate.FilterPredicate = new Predicate<GridViewRowInfo>(PerformFiltering);

}

else

{

tree.MasterTemplate.FilterPredicate = null;

}

tree.EndEdit();

}

private bool PerformFiltering(GridViewRowInfo row)

{

return (decimal)row.Cells["UnitPrice"].Value > 30;

}

But nothing happens when I fire the ChangeFilter() - the data still unfiltered. Do you know please, ehat am I doing wrong, or how can I fire filtering process from code?

Nested Grid Theme

Hi Telerik,

I have a nested grid and would like to apply different theme for each child grid. Is it possible to do such thing?
For example:

- the first grid uses Aqua theme
    - the 1st child grid uses Desert
        - the 2nd child uses Office 2010

Another option is to have different color for each grid.

Regards,

Alep

AppointmentBackgroundInfo

I am working on a screen that uses the scheduler. I only want to show the month view and place the different tasks on the calendar. I have this working the main issue I am having is I would like to color the background based on our own internal status. As of right now I have been able to use the AppointmentFormatting to change the colors and have it display the way I would like. I also see that I could add AppointmentBackgroundInfo so for Status Id's that already exist are no issue. Is there a way to override the existing status backcolor and gradientstyle?

mouse scrol combobox gridview

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
