Sorry, Dheeraj, but I don't understand your question about the mouse.

In terms of filling a grid, you can grab the values of individual cells in the attribute table via sf.Table.get_CellValue, then place them in a grid. Since the attribute table is essentially a dBase table you can also retrieve data using a foxpro or dBase driver via sql select statements into a DataReader or DataTable, then either populate the grid by hand or bind to the DT. Under no circumstances would you ever want to do any inserts or deletes using this method, however,

Hi DonRahmlow,
First Thanks for the reply,

My question is :-
Q1.) On mouse move event on Axmap it is showing tooltip or attribute of each polygon but not for the line or point layer...
Q2.) Tooltip is showing even after selecting ZoomIn tool etc, so i want to reset that. I don't want tooltip to show while having zoomin/zoomout tool on map.
as in example it is on MouseMoveEvent.
i want after selecting ZoomIn/Out tool, Tooltip should not be displayed on MouseMoveEvent on Axmap._____
This is the example below which i followed.

Q1: that is because proximity detection is being performed only on a single sf/layer
Q2: you could remove the popup label if the mouse moves and it is not close to a shape

Dear DonRahmlow,

Thanks for the reply and with your suggestion my problem(Q.2) is solved..
but can u explain me how can i show tooltip on point or line layer...(With what changes)...?

Hi Dheeraj--You just need to run the code in the example for every sf loaded as a layer for which you want the tooltip to appear. The example works on a single layer only.
