Windows Forms app -

I want to set focus upon form activate to a infragistics Ultragrid.  I'm calling grid.focus() as the last line of code in form activate.    However, the grid does not have focus.   And I can't seem to determine where the focus is.     Hitting tab once will give the grid focus.  Is there anything odd about focus and the Ultragrid?  Do I also need to give focus to a row?

you may check the public property 'CanFocus' which seems to indicate whether the ultra grid can have the focus. it perhaps depends on whether the grid has editable cells.

if you want to select a row or cell rather than to setting the focus to the control, i found an answer at infragistic forum (http://www.infragistics.com/community/forums/t/31880.aspx):

The grid follows the current record of the data source to which it is bound by default, meaning you would just have to set the binding manager's Position property to the index of the record that you want to "select":

UltraGrid grid = this.ultraGrid;
BindingManagerBase bm = grid.BindingContext[grid.DataSource, grid.DataMember];
bm.Position = 0;

Note that you can also select and activate an UltraGridRow programmatically; set the UltraGrid.ActiveRow property to activate the row, and use the Rows property of the Selected object to select a row:

this.ultraGrid.ActiveRow = row;
this.ultraGrid.Selected.Rows.Add( row );

perhaps you have to set an active row in order to get the focus to the grid.

note the ultragrid also has property ActiveCell which could be set same as ActiveRow.

The grid does not have any editable cells.  However, I can give it focus just by clicking anywhere within the grid.   That's all I want to do in code - give it focus.

this can happen if some other control of your form gets the focus later. normally it is the first control in your form which has windows style bit WS_TABSTOP enabled. you may try to set the focus later. to see whether setting focus works at all you may add a button to your form and call grid.focus(); when the button was clicked.

did you check whether grid.canfocus is true or false?

ah, grid.canfocus is false, right after I call  grid.Focus() in form.activated.   So, where should I call grid.Focus() ?  Isn't form.activated the last form event?
