ContextMenu custom item weird display

Hello,

I'm trying to add custom menu item to the header cells context menu but i have weird display when i am using derived class instead of RadMenuItem class directly (see attached image).

Can you explain to me what is wrong with my code ?

public class CustomOpMenuItem : RadMenuItem

{

private MyForm _form;

private int _columnIndex;

private CustomOp _op;

public CustomOpMenuItem (MyForm form, int columnIndex, CustomOp op)

{

_op = op;

switch(_op)

{

case CustomOp.CUSTOM1:

this.Text = "Custom 1";

break;

case CustomOp.CUSTOM2:

this.Text = "Custom 2";

break;

case CustomOp.CUSTOM3:

this.Text = "Custom 3";

break;

}

_columnIndex = columnIndex;

_form = form;

this.Click += onClick;

}

private void onClick(object sender, EventArgs e)

{

_form.DoCustomOp(_columnIndex,_op);

}

private void onContextMenuOpening(object sender, VirtualGridContextMenuOpeningEventArgs e)

{

for (int i = 0; i < e.ContextMenu.Items.Count; i++)

{

if (e.ContextMenu.Items[i].Text == "Pinned state")

{

// hide the Delete option from the context menu

e.ContextMenu.Items[i].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

if(i != 0)

{

// hide the separator before the Delete option

e.ContextMenu.Items[i - 1].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

}

if (e.RowIndex == RadVirtualGrid.HeaderRowIndex)

{

RadMenuSeparatorItem separator = new RadMenuSeparatorItem();

e.ContextMenu.Items.Add(separator);

RadMenuItem customMenuItem = new RadMenuItem();

customMenuItem.Text = "Custom Data Operation";

e.ContextMenu.Items.Add(customMenuItem);

e.ContextMenu.Items.Add(separator);

e.ContextMenu.Items.Add(new CustomOpMenuItem(this, e.ColumnIndex, CustomOp.CUSTOM2));

e.ContextMenu.Items.Add(separator);

e.ContextMenu.Items.Add(new CustomOpMenuItem(this, e.ColumnIndex, CustomOp.CUSTOM3));

}

Regards.

Time and Date on same axis

Looking at some options for modernizing an old scheduling application.

Is it possible to set scheduler to put the time and date on the same axis? All the demos/documentation I can find do not show anything similar.

Select RadTextBox in RadForm on Load

I have a RadForm that contains multiple Radtextboxes. How can I have one of them be the focused box once the form has opened?

I have tried placing both lines of code below in the constructor but neither initialize the cursor in the iUSERNAME text box.

this-object:iUSERNAME:Focus().
this-object:iUSERNAME:Select().

Thanks

Page size & direction

Hi, I'm evaluating this control.

I'm opening a docx file in the control as a RadDocument. The file is right to left file and showing two pages on the screen in the wrong direction (page 1 on the left) - event when I change the control to RightToLeft=Yes (this only changes the scroll to the other side).

I would like one of two options:

1. Show only one page on the screen at a time (scroll down will go to second page). I found this can be done when making my window small but I'd like it to open maximized.

2. Show two pages but in the correct direction (page 1 on the right and page 2 on the left).

Any help?

Thanks!!

Programatic Printing Wrong Size

When I use RadPdfViewer1.Print() or RadPdfViewer1.Print(True) to print, the printed document has been shrunk. If I use the Navigator it prints fine.

I did some testing this morning and have discovered that I get the same results with using RadPrintDocument to print using RadPrintDocument1.Print.

What do I need to do to make this work properly?

RadCheckedDropDownList focusing popups?

Hello ,

I am trying to use a radCheckedDropDown list in a winforms application (C#). The list is working the way I want it to except for 1 thing.

When I click the dropdown list it shows (which is correct) however while it is open if I start to type in the text area the text popup shows in front of the dropdown popup, and as a result you can click through to the drop down list. What I would like is to close the dropdown portion when typing, and vice versa when using the drop down list.

If I use a standard combobox I can accomplish this by hooking the preview and the droppeddown events, however the radcheckeddropdownlist does not have the droppeddown event.

private void comboBox_DropDown(object sender, EventArgs e)

{

ComboBox cbo = (ComboBox)sender; cbo.PreviewKeyDown += new PreviewKeyDownEventHandler(comboBox_PreviewKeyDown);

}

private void comboBox_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)

{

ComboBox cbo = (ComboBox)sender;

cbo.PreviewKeyDown -= comboBox_PreviewKeyDown;

if (cbo.DroppedDown) cbo.Focus();

}

Thanks,

Jeff
