Row Scroll

[Administrator]

How do i scroll to the top row ? We have grid that is dynamically updated whenever a new records appear i want the grid to scroll at top most row (the grid is sorted by id in descending order so new record will always appear in top)

I treid with currencymanager.position =0 but i don''t see grid scrolling to the top row then i implemented this code
this.Binder.CurrentPosition=0;
this.ScrollCellInView(1,1);

but now i see a painting problem ? any clue..

Try setting this.grid.TopRowIndex = 1;

i tried that but the arrow pointer which is the column 0 in this case doesn''t point to top row...i still see the ">" pointer displayed on previous selected row not on new row.

Also use this.grid.Binder.CurrentPosition = 0;

If you also want to move the current cell, also use grid.CurrentCell.MoveTo(1,1);

pls find attached bitmap which describes the current behaviour.. we have created our dervied class that extends griddataboudn

as u can see the following code is inserted in this class

private void Model_RowsInserted(object sender, GridRangeInsertedEventArgs e)
{
if ( this.Model.RowCount == 1 )
{
this.Model.ColWidths.ResizeToFit(GridRangeInfo.Table());
}
if (this.Binder.CurrentRowIndex == 2 || this.Binder.CurrentRowIndex == 1)
{
this.TopRowIndex=1;
this.CurrentCell.MoveTo(1,1);
}
}

now we see a painting problem... (note : i cannot uplaod the bitmap because the upload window is taking hell lot of time to appear)

for example if the grid contains following rows

ID Trader Name
3 AA
2 BB
1 CC

and when new records appear the grid will look like as describe dbelow.

ID Trader Name
3 AA
3 AA
2 BB
1 CC

but now when i go and click on any of the cells of the first two rows redraw happesn properly

ID Trader Name
4 DD
3 AA
2 BB
1 CC

Also there is a code in PreparviewStyleinfo which does some coloring stuff.. but nothing major ...

Hope this explains a bit

If you can send a sample project showing teh problem to [email protected], we can try to spot the problem here. Something else to try:

this.Binder.EndEdit();
this.TopRowIndex=1;
this.CurrentCell.MoveTo(1,1);
this.Refresh();
