How to implement CEditListCtrl?. List control with edit capabality (Report/Grid view).
I have a list view in Report View. It has some values. I need to extend this to edit the values present in the list view.
I declared a class which inherits from CListCtrl. And I have handled the two Window messages to start and end the edit. Upon getting the messages I am displaying a Text box. But I am not getting the control inside these message handlers. Is there a way to know the reason?
Or Is there a other way to implement this.
There are some neat grid controls on Code Project which might help:

Thanks for all answers
I have done it easily.
I have handled the WM_LBUTTONDOWN. This handler pops up the edit box to get the new
value for the field
Handled LVN_ENDLABELEDIT to know the end of update.
After receiving the above message, updated the values.
“One thing I forgotten was to set the flag in the resource view for CListCtrl (Edit Labels to TRUE)”
We have to implement OnPaint() (in CListCtrl's derived class) also otherwise the UI won't update properly
You need to use a CComboBox which is basically a combined CEdit and CListCtrl

How can I sort Items in CListCtrl when the button is clicked?
I made a Dialog based application in MFC.
I put CListCtrl control on my Dialog and set its view style to report type.
I have two columns in this list view.
In here when I clicked the "Sorting" button, it should sort item in the list.
I saw many examples related to this, but none is working for me.
Can some one guide me how to do that?
I assume that you mean the column header when you write "sorting button".
You probably forgot to put this into the message map of your dialog:
ON_NOTIFY(LVN_COLUMNCLICK, IDC_LIST1, OnColumnclickList1)
IDC_LIST1 is the id of the list control which may be different in your code.
Are you somewhat familiar with MFC ? If not, you should follow one of the numerous tutorials available on the net.
I would use a CMFCListCtrl. It is easier, as it as built in sorting functionality and you only have to provide a function with the comparing items algorithm for sorting. I have succeeded using it. You have to override the OnCompareItems on your class derived from CMFCListCtrl. I also recommend you to do a call to EnableMarkSortedColumn(); after your list is created.
The CListCtrl has a SortItems method.
All you need to do is provide your Compare function to it as the parameter.
I don't know much about the contents of your list control so I can't really give you more information.
Please read up on it and extend your question with example code and details of which column needs to be sorted and I can help more.
If the contents of your cells are just text then I usually just return the value of:
return Value1.CollateNoCase(Value2);
There are also lots of tutorials on the Internet. For example:
http://www.codeproject.com/Articles/27774/CListCtrl-and-sorting-rows
In fact, that tutorial suggests us in SortItemsEx. That is what I would use.
I want to hide or disable Items with SetItemState(). The CListCtrl is in Report View.
It must be something like this m_List.SetItemState(1, DISABLE, DISABLE);
I searched but didnt find the right nState
If there is another solution than SetItemState, it also will be ok
Can anyone help me?
There is no item state to represent a disabled (grayed) item. See docs
The only way to solve this is your own implementation and using custom draw. That is the way I do it.
You can easily prevent the user to select an item when you trap LVN_ITEMCHANGING. Just filter the state Change to LVIS_SELECTED and return TRUE to prevent the change.
You can give visual feedback. I would derive a class CMFCListCtrl and override OnGetCellBkColor and OnGetCellTextColor methods to achieve it.
And I would override the its response to selection to unselect when selecting an unselectable item. However for this part, I am not so sure if it is doable.
I want to embed two generic buttons like "Select" and "Cancel" to CMFCPropertyGridCtrl property line. Is there a painless way to do that?
Found a solution myself. You can use OnCreateEditor virtual method to send a custom control to a property. Note, that it will be shown on property edit. Another important note, that CMFCPropertyGridCtrl calls OnCreateEditor each time the user edits the property but before the control is destroyed it deletes the last received CWnd object itself. You should consider that. I have found no notes about that in MSDN CMFCPropertyGridProperty documentation (you know what to say).
I have two CListCtrl objects in my form. I want selected list in both of them be same.
How I can do it.
I want duplicate the message that sent to a ClistCtrl and send to other one.
How I can do it?
if this is a good way?
thanks herzl
So, essentially what you're saying is that you want the lists to be synchronized.
You can easily achieve that by adding an event handler to catch the user's selection inside you list control, by adding: ON_NOTIFY(LVN_ITEMCHANGED, IDC_LIST1, OnItemChangedList1) to your dialog/window's message-map.
Inside OnItemChangedList1(), get the index of the currently selected item by calling GetFirstSelectedItemPosition(), and set that as the current index in your second list by calling SetSelectionMark().
This way, whenever the user will click on the 2nd item, for example, in List_A, the 2nd item in List_B will be selected as well.
There ought to be a function that brings that row into view, if it's not in view already, but I can't find it.
I hope that raps it up, ListView's have changed a lot since I've used them, but feel free to ask more if anything is unclear.
We want some items in a CListView to appear like hypertext links.
I can make everything underlined by setting the lfUnderline flag in LOGFONT, and creating a font from this, before calling SetFont - but this applies to the whole CListView.
Does anyone know how to make individual items in a CListView to appear underlined?
You can do this by using the custom-draw notifications and modifying the font on the particular item you want within the custom-draw handler.
See this link for details.
Try this:
oMyCListView.SetExtendedStyle(LVS_EX_ONECLICKACTIVATE)
