This control is the best control CJ developed so far... There are just a handfull of (known) problems with this control so that's a good thing, right? (But if no one from support ever replies in this post the problems will grow and grow and it isn't the best control anymore )  But it's time for some improvements. Please reply if you feel like that we need a new feature and/or need to fix an issue 

1. I don't know if this is normal behaviour but tooltip doesn't show actual value of item when first time mouse hoovers item. Only when mouse hoovers the second time it shows actual value of PropertyItem.  See post: https://forum.codejock.com/forum_posts.asp?TID=16124 - https://forum.codejock.com/forum_posts.asp?TID=16124  Test project is present
2. The button doesn't get updated with newly assigned value (Caption, icon, etc...) Without LockRedraw the value gets updated until item is selected / resized (I guess internal redraw) See post: https://forum.codejock.com/forum_posts.asp?TID=11199 - https://forum.codejock.com/forum_posts.asp?TID=11199
3. PropertyGridEnumFlags limited to 32 childs. See post: https://forum.codejock.com/forum_posts.asp?TID=16132 - https://forum.codejock.com/forum_posts.asp?TID=16132
4. Icon alignment in caption with MultiLine. See post: https://forum.codejock.com/forum_posts.asp?TID=13542 - https://forum.codejock.com/forum_posts.asp?TID=13542
5. Tooltip still shows even when set with DrawTextWordBreak. https://forum.codejock.com/forum_posts.asp?TID=16063 - https://forum.codejock.com/forum_posts.asp?TID=16063  SOLVED in V13.3.2
6. With wndPropertyGrid.NavigateCaptions = False the arrow up/down key will set focus to Caption side and not on the Value side as I would expect
7. Navigating Items (PropertyBool & CheckBoxStyle = True) doesn't work. @JohnP
8. Description text of first item doesn't show at startup. The caption rectangle shows, but description in Help section doesn't.
9. Clicking checkbox in value part is causing the caption selection to show and hide again.
10. Check Color properties in PropertyGrid control, I uploaded test project (see below) and I would like a comment.
11. Why does SelectionChanged event fire when just clicking on same item? Expanding item will fire event even twice. Even clicking InplaceButton fires the event. Why, why, why?  

1. Automatic sizing of PropertyGrid Multiline item while typing text into multiline.
2. .DefaultValue property should contain same type as .Value in order to compare both values. Now you have to do a lot of "workarounds" to compare the values if .Value has been changed.
3. If 2. can't be accomplished we would like to have the .HighlightChangedItem made public. This way can check if the value has been changed more easely.
4. SetMask could use some improvements. (or maybe I don't understand how it works ) If you (forummember) agree let me hear your opinion.
5. Markup for propertygrid values (now it supports only captions)
6. Method GetRect returns values for entire item, would like same method for only the value part.
7. SplitterPos changed event would be a nice option to have for calculations with PropertyGridItem value part  
8. If issue .6 isn't a bug: Focus only on the value side of the grid. @wakerunner - https://forum.codejock.com/forum_posts.asp?TID=16240 - https://forum.codejock.com/forum_posts.asp?TID=16240  
9. Slider and spinner controls always visible. @nighthawk -  https://forum.codejock.com/forum_posts.asp?TID=12889 - https://forum.codejock.com/forum_posts.asp?TID=12889
10. Add EditStyleAlpha, allowing only characters a-z/A-Z @nighthawk
11. Maybe the most useful thing would be to have a BeforeEditChange(NewValue, Cancel) event. This would fire after the user does something that will change the value of PropertyGridItem (for example, types on the keyboard, pastes/cuts from/to the clipboard). You could then handle any case (alpha, numeric, alphanumeric, currency, different languages, etc...). NewValue would be what the item value is going to be changed to, and you could set Cancel = True in code to prevent the change from taking place. @jpbro (see reply somewhere below)
12. Property DefaultCategoryItemHeight & DefaultItemHeight  I use PropertyGrid control for all settings in my project and use a lot of InplaceButtons with icons on it. Icons are 16x16 but with current "default" height the Inplacebutton is a few pixels too small to fit the icon so I have to set the PropertyItem height everytime !!! I think it looks "messy" when having different heights so all my Category items have same height also when it's without an InplaceButton with icon
13. Option to set splitter in pixels. Maybe wndPropertyGrid.SetSplitterPos [0 <> 1 in percentage]  or  [> 1 in pixels]

If the user presses the shortcut key (F5) and a save function is called the grid does not lose focus. I just added some code to setfocus to the button before calling the save function so it does lose focus when F5 is pushed.

johnp wrote: Let me add a couple of suggestions as well (if these are already available I apologize but I could not find them):   1. add editstyle options for alphaonly and alphanumeric only. I know that  an edit mask could be used but there is a numeric only editstyle so adding these other two seems to make sense. 2. in the afteredit event if you set cancel = true then control/focus should return to the item that was being editted. As far as I can tell, the focus goes to the next item in the grid. 3. when navigating through a grid with the tab key (navigate captions set to false) it seems to skip boolean items if the checkbox style is set to true (i am not sure what happens if the checkbox style is set to false)

1. Item.EditStyle = EditStyleNumber is for entering ONLY numbers (or I don't understand what you mean )
2. I tested this and the focus remains on item (you can't see it but try to type a character again)
3. You are right ! It doesn't matter if True or False. I will add this to my list, thanks

Hi,

Why does it have to take almost a year before support is replying. It feels like I'm totally invisible in this forum  There are two CJ controls (RC and PG) which I use in every application (ChartControl would be third one) and get a minimum of answers. Well, don't like that at all...
