I have this ElementsDataGrid class which is in ElementList class:
public class ElementList : System.Windows.Forms.UserControl
{
private class ElementsDataGrid : System.Windows.Forms.DataGrid
{
internal void ScrollToRow(int aRowNum)
{
this.GridVScrolled(this, new
ScrollEventArgs(ScrollEventType.LargeIncrement, aRowNum));
}
}
private bool m_autoScroll;
private InfraControls.ElementList.ElementsDataGrid m_DataGrid;
[Description("Determines whether the grid will scroll down when a new row
is added."),
Category("Layout")]
public override bool AutoScroll
{
get { return m_autoScroll; }
set { m_autoScroll = value; }
}
public void SetDataSource(DataView data)
{
m_DataGrid.DataSource = data;
data.AllowNew = false;
}
private void DoAutoScroll()
{
if( m_autoScroll )
{
m_DataGrid.ScrollToRow((m_DataGrid.DataSource as DataView).Count-1);
}
}
private void AddDefects(object aSender, ArrayList aDefectRows)
{
DoAutoScroll();
}
}
Defects are added to the DataSet, causing the ElementsDataGrid to be added
with more rows and invoking the AddDefects() that invoke the DoAutoScroll().
And the DoAutoScroll() is invoked causing the vertical scrollbar of the
ElementsDataGrid to move --> the focus is taken to the ElementsDataGrid. And
this is the problem I wish to avoid.
The code is larger then what I have posted in here, I couldn’t post all of
it in here (much too much). I hope this post can help resolving this problem.
