Hello,
I have a grid working in SelectionModeEnum.ListBox mode.
I have a ContextMenu on the grid.
When user RightMouse Clicks I want the grid to select the row and popup the menu. Is this possible?
* Like the behaviour of Microsoft Excel and Outlook *
The row select must be smart, if user has selected multiple rows using left mouse and ctrl/shift then they right click it should not change the row selection.

Here is the solution:
int row=c1FlexGrid1.MouseRow;
int col=c1FlexGrid1.MouseCol;
if (e.Button==MouseButtons.Right && row > c1FlexGrid1.Rows.Fixed)
{
// Test by selection mode
if (c1FlexGrid1.SelectionMode == C1.Win.C1FlexGrid.SelectionModeEnum.ListBox)
{
// clicked on unselected row, so change selection.
if (!c1FlexGrid1.Rows[row].Selected)
{
c1FlexGrid1.Row=row;
}
}
else
{
if (!c1FlexGrid1.Selection.Contains(c1FlexGrid1.MouseRow,c1FlexGrid1.MouseCol))
{
c1FlexGrid1.Select(c1FlexGrid1.MouseRow, c1FlexGrid1.MouseCol);
}
}
}

The code below goes in the BeforeMouseDown event handler.

Kevin,
When I put the code “int row= c1FlexGrid1.MouseRow
and int col=c1FlexGrid1.MouseCol” in my BeforeMouseDown event handler, The row, col is -1(0xffff) when i right click the mouse, even my mouse point is on the row of the grid, the left mouse click is working fine. What could be the problem?
