GGC, CellTipText and QueryCellStyleInfo

[John H]

Hi,
Im currently using the PrepareViewStyleInfo event to set the CellTipText for a given column, but this gets run everytime ot paints the cell.

I only want to set the CellTipText when the mouse is hovering ober the cell. From your forum I found the QueryCellStyleInfo event which sounds like what I want, but I cant find it on a GGC.

Any ideas?

Thanks
John

Hi Haneef,
My bad, I actually wanted to see how to do this on the GridControl. I don't see a QueryCellStyleInfo event.

Thanks
John

Hi John,

For GridControl, The QueryCellStyleInfo event is named as QueryCellInfo event. Please try the code snippet and let me know if this helps.

this.gridControl1.QueryCellInfo +=new GridQueryCellInfoEventHandler(gridControl1_QueryCellInfo);
private void gridControl1_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)
{
if( e.ColIndex == 2)
{
e.Style.CellTipText = "Welcome";
}
}

Best regards,
Haneef

Hi Haneef,
The event doesn't fire for me, to I have to enable a property or change something else?

Thanks

Hi Haneef,
Thanks for the example, but if you notice that even gets fired when painting the cell as well as when the mouse moved over it, so if you have 10 rows visible it will trigger the event at least 12 times.
I have code that takes a small amount of time to return, having that code run 10 or more times when its not needed is a waste and could show a slight delay in my app.

Any ideas?
Thanks
John
