We are using the standard Header control from the OS common controls lib. We need to force the control to refresh the area related to only one column header (item). Is there a special WinAPI message for that, or a trick we could use?
Use the HDM_GETITEMRECT message to get the rectangle for the item in question, then refresh it using the InvalidateRect function.
We've used the following trick as the column header texts aren't stored directly in the header (VB6 code):
Dim tHI As HD_ITEM
tHI.mask = HDI_TEXT
SendMessage m_hWnd, HDM_SETITEM, lCol, tHI
In fact, we do not change the item, but the header "thinks" it happened so actually we force the header to redraw the item.
Caution: HDN_ITEMCHANGING is sent in this case, so ignore it when using this trick.

I am creating a MFC application based on example: https://github.com/microsoft/VCSamples/tree/master/VC2010Samples/MFC/Visual%20C%2B%2B%202008%20Feature%20Pack/WordPad
now i want to change the way to expand font name drop list in toolbar from DOWN key to F4. It seems i need to get the combobox and call SetExtenedUI(FALSE) on it, but i dont know where to do it.
To change the extended UI flag on a CComboBox, you call its CComboBox::SetExtendedUI member. When you have a CMFCToolBarFontComboBox you need to get to its combo box first. Since it inherits from CMFCToolBarComboBoxButton you can use its CMFCToolBarComboBoxButton::GetComboBox member to get a CComboBox*.
CMFCToolBarFontComboBox* pFontButton = ...;
CComboBox* pComboBox = pFontButton->GetComboBox();
pComboBox->SetExtendedUI(FALSE);
finally i switched to CComboBoxEx which works fine
I have a sap.m.TabContainer control with multiple sap.m.TabContainerItem controls. Each of the TabContainerItem controls have a number of their own controls on them. I have created a custom control (DBPanel) with a label and text field. It also has an enabled property for which I have overridden the setEnabled(boolean) method to enable/disable the internal text field within DBPanel. There are five (5) of these DBPanel controls on a specific TabContainerItem. When I call setEnabled(true) on each of these DBPanels, only three of the five become enabled. When I switch to another TabContainerItem and then back to this one, the final two DBPanels are also enabled. It is almost as if the TabContainerItem needs to be re-rendered. But I have read elsewhere that if rerender or invalidate need to be specifically called then there is something wrong with the code.
Any help would be appreciated.
Thank you
At your overridden method, you can try to call the original method that is extended. If you don't need extra logic rather than disabling or enabling it, you don't need to extend that method but I guess you have some.
First check whether superclass implements the method and then call the
method with the original arguments
if (DBPanel.prototype.setEnabled)
DBPanel.prototype.setEnabled.apply(this, arguments);
Am using the free jqgrid , to keep it short, am getting method not found on fixScrollOffsetAndhBoxPadding when I try to set the height of the jqgrid via the below code in beforeProcessing().
$grid.setGridHeight(200).trigger("reloadGrid");
The reason I need to set the height is, when rownNum is <10, i want height as auto. but wen the rowNum is >10, i need the grid to have a vertical scrollbar. But when setting this height, I get to see the javascript error which says, fixScrollOffsetAndhBoxPadding is not an object or property.
error:
SCRIPT438: Object doesn't support property or method 'fixScrollOffsetAndhBoxPadding'
jquery.jqgrid.min.js, line 202 character 381
I think that the origin of your problem could be wrong usage of setGridHeight or the usage of setGridHeight before you created the grid in $grid (for example $grid can be wrong and you should use $(this) instead). You didn't posted where in your code you use the lines. Free jqGrid set fixScrollOffsetAndhBoxPadding property of $grid[0] during creating of the grid (before onInitGrid is called).
One more important remark: you should be always very carefully in the usage of reloadGrid inside of other callbacks. You should understand the reloadGrid works synchronously. It means that the next line after reloadGrid will be executed after trigger("reloadGrid") is finished. For example you loads the 5-th page returned from the server. The call of trigger("reloadGrid") will reset page parameter of jqGrid, it can change datatype, place new Ajax request and so on. So I strictly recommend to use trigger("reloadGrid") only inside of setTimeout. In the way you can allow jqGrid to process the current request till the end and later make reloading:
$grid.setGridHeight(200);
setTimeout(function () {
$grid.trigger("reloadGrid");
}, 50);
It the above will not help then you should 1) use jquery.jqgrid.src.js instead of jquery.jqgrid.min.js to report the error; 2) write which version of free jqGrid you use (4.9.1, 4.9 or the current code from GitHub); 3) post more full example which can be used to reproduce the problem. One can easy localize the origin of the problem by debugging of the code, but one have to guess about the reason if one see only one line of code (or some small code fragment).
I've been working on a custom field, which contains a list.
I have to be able to edit the selected item on the list in a richtext editor. (this is the only missing part).
I've read the topic on opening from c# code Opening Rich Text Editor in custom field of Sitecore Content Editor .
This works nice for the "add" button, since i have to open the RTE empty(with default text...), but not for the Edit button.
My aproaches are:
Somehow in the Edit button's message field list:edit(id=$Target) pass the selected index (like list:edit(id=$Target,index=$SelectedIndex), but i don't know how to populate $SelectedIndex
Somehow in the overridden HandleMessage method get the list's selected index. I'm able to get the selected value Sitecore.Context.ClientPage.ClientRequest.Form[ID of list], but thats alone not much of a help, since i won't be able to decide which one to edit if two listitem equals.
Do the richtext editor opening and handling fully in javascript. As i saw at some script in content editor, i tried to do that, but i can't understand it clearly:
richtext editor url:
var page = "/sitecore/shell/Controls/Rich Text Editor/EditorPage.aspx";
some params :
var params = "?da=core&id&ed=" + id + "&vs=1&la=en&fld=" + id + "&so&di=0&hdl=H14074466&us=sitecore%5cadmin&mo";
and the part where i'm not sure:
var result = scForm.browser.showModalDialog(page + params, new Array(window), "dialogHeight:650px; dialogWidth:900px;");
This way the RTE opens as expected (i guess i could get the selected index from javascript and pass it as a parameter later). However when i click ok, i get exception from EditorPage.js saveRichText function: Cannot read property 'ownerDocument' of null. Am i missing some parameter?
Either of the three aproaches is fine for me(also i'm open for new better ones) as soon as i'm able to do it.
Thanks in advance!

I was able to enter some javascript into the message:
list:Edit(id=$Target,index='+document.getElementById(ID of the select using $Target ).selectedIndex+')
this way i got the index in HandleMessage.
I'm waiting for better solutions now.
I recently started another thread without an account, so I'm reposting the question here with an account so I can edit current links to the program so other users can follow this. I have also updated the code below. Here is my original question:
I read the other post here on Outlineviews and DND, but I can't get my program to work. At the bottom of this post is a link to a zip of my project. Its very basic with only an outlineview and button. I want it to receive text files being dropped on it, but something is wrong with my code or connections. I tried following Apple's example code of their NSOutline Drag and Drop, but I'm missing something. 1 difference is my program is a document based program and their example isn't. I set the File's Owner to receive delegate actions, since that's where my code to handle drag and drop is, as well as a button action. Its probably a simple mistake, so could someone please look at it and tell me what I'm doing wrong? Here is a link to the file: http://dl.dropbox.com/u/7195844/OutlineDragDrop1.zip
You're not responding to NSOutlineView's drag-validation message.
Your original code implemented tableView:validateDrop:proposedRow:proposedChildIndex:. As I pointed out on that question, that's wrong when your table view is an outline view; NSOutlineView will not send a table-view drag-validation message, only an outline-view drag validation message.
You've since changed your drag-validation method to be declared like so:
- (NSDragOperation)outlineView:(NSOutlineView*)view
validateDrop:(id <NSDraggingInfo>)info
proposedRow:(int)row
proposedChildIndex:(NSInteger)index
But nothing actually sends such a message.
Remember that NSOutlineView rarely deals with row indexes, since those can change as parent rows are expanded and collapsed. It deals instead with “items”, which are generally model objects.
Therefore, the correct validation method is:
- (NSDragOperation)outlineView:(NSOutlineView*)view
validateDrop:(id <NSDraggingInfo>)info
proposedItem:(id)item
proposedChildIndex:(NSInteger)index
Notice the name of the third component of the selector, and the type and name of the argument that goes with it.
With this change applied, your data source validates drops.
