If your selection mode is such that a whole row is selected, I am pretty sure you cannot select something other a whole row.

You could maybe "fudge" it a little. Set your SelectionMode to CellSelect.
Then in the various click events (cell mouse click ?), if its NOT on a column header, set the selected cells to be all the cells in a row. You will probably also have to handle something if they use the arrow keys to change the selection
That should effectively create the 'full row select' effect.
If it *IS* a column header, set all the cells in that column as selectedcells.

You would have to play with it a bit, but it should work

I tried

DataGridViewSel ectedCellCollec tion obj = null;

obj[index].value = datagridview[column,row].value;
}

You are getting a null reference because you are setting the object to null!
Right here:
DataGridViewSel ectedCellCollec tion obj = null;

You get error because there are rows that you haven't set value to. If you set value to all cells in your DGV then you will not get that error again. You're on the right track with your code, but if you want to click a cell within the Grid to select all row that cell belong to you can combine with cell click event and you will get position of that cell in event argument --> easier.

i assign a menu to entire column in the datagridview,th en when i click select entire column frm the menuiten then what i want is the entire column should be selected in to an object which is of type DataGridViewSel ectedCellCollec tion.

I want this because i already have made a function which takes selected cell values so tht i dnt need to modify the functions.
