Hello,
I would like to ask you a question regarding the CExtGridWnd object. I am working on VS2005 MFC with profuis 2.8.2.
I have created a class called CProdGridWnd derived from CExtGridWnd. Also I Created a Dialog Template with a Custom control (Class ProfUIS-ScrollItemWindow) which I use to put the grid in.
That works fine on a normal dialog box.
But If I try to use your CExtResizableDialog combined with CExtControlBar to convert this dialog into a dockable window in a document-view MFC project, the grid is invisible. In fact if I put any other control on the form it works fine, but the area of the custom control that includes the grid is just white. The peculiar thing is that other than that the grid works. When clicking randomly on that white area the grid events run and with a double click, an edit box appears with the data of the cell under it to change. When changing it and pressing enter, the OnGridCellInputComplete event runs as it should, but the cell and the data just typed disappear again.
Could you help me make the Grid Control visible again?
I tried to combine 2 of your examples the Dialog View in the SDIDOCVIEW project and the CExtGridWnd in ProfUIS_Controls project. I would like to attach the small test project I created so that you can see the problem. Please send me an email to dbalotis@bsi.gr to send you this project. The code bellow are the most important parts of the test project.
I would appreciate your answer the soonest possible and thank you for your time in advance.
Merry Xmas
