Hi,
I have to show few details in datagrid's tooltip dynamically as the mouse hover on the particular row. I am not using datagridview.
I am getting the dataonly when clicking on the particular row of the grid as focus of the desired row get sets. But i need the same without clicking on the grid and just on mouse pointer over it.

Please suggest if have any solution.

Note: I had found solutions for ASP.Net over net but not for WinForms.. and my project is of WinForms only.

Regards,

Solution 1

This is exactly how ToolTip is designed — it works on mouse hover; and a control does not matter. However, you can use additional events specific to the control to modify a ToolTip text. The usage of it not completely intuitive; one unusual thing is that one ToolTip instance works for multiple control.

The code sample of this MSDM page is good enough to start:

SaKryukov,
thanks for your reply, but the problem i am facing is getting the pointed row of the datagrid..
I need the help for datagrid. :)

Sergey Alexandrovich Kryukov 29-Apr-11 4:00am

I see. The additional event you need would be MouseMove (unfortunately). You will need to find out how to locate individual row by mouse coordinate and certainly the scroll bar position. Well, for help on Data Grid, read MSDN help on Data Grid...

Tried but no clue :(

Did you run event handler(s) under debugger? "No clue" does not describe the issue. Not firing, not showing tooltip..?

Yeah i did.. but unable to select the desired row on mouse hover over the grid.

Sergey Alexandrovich Kryukov 2-May-11 0:31am

Well, it may require a hard way I described above: calculation of the row based on mouse coordinates and scroll position. Maybe it's easier to use currently selected row (selected in a normal way) and show tool tip for the entire control but relevant to the selected row.
I also don't understand "I am not using datagridview". What is the control you're talking about?

over other forums there were few suggestions to implement the above case by using some cell eventhandler, but that was ment for datagridview only, and i can't use that method as i am using a datagrid or to be more precisely a Syncfusion virtual datagrid. this do possess all features of normal grid with some additional specialities.

Sergey Alexandrovich Kryukov 2-May-11 4:35am

You still did not answer what control do you use. If there is a cell handler it would not be a problem, but it looks like you know about it.

i am using a simple Syncfusion grid control

Sergey Alexandrovich Kryukov 2-May-11 6:18am

Aaa, third-party... Then I don't know but I think we considered all thinkable alternatives. You just need to review the controls events and properties and see which of the ways are applicable. If you doubt, point out what events you tried to use and what's the problem.
