How do I scroll DataGrid to specified row index?

[MrNobody]

I want to know how to scroll a DataGrid so that a specific row index will be
visible to the user?

[PJ Olson]

Us the CurrentRowIndex member to set the row you want visible.

Hi,

I'm trying to do auto scroll for my DataGrid, but each absolution I find
steal the focus to the DataGrid.
I also tried your suggestion using the CurrentRowIndex , but it also steals
the focus.

See my post regarding the other solution I tried:

Can you tell how to do auto scrolling without stealing the focus?

Hi Sharon,

Thanks for your post.

I am not sure why SendMessage does not work for you. As we negotiated in
the original post, this solution should work for you.(Actually, it works
well on my side.) If not, can you show me a little sample to demonstrate
the problem?

Thanks

I have this ElementsDataGri d class which is in ElementList class:

public class ElementList : System.Windows. Forms.UserContr ol
{
private class ElementsDataGri d : System.Windows. Forms.DataGrid
{
internal void ScrollToRow(int aRowNum)
{
this.GridVScrol led(this, new
ScrollEventArgs (ScrollEventTyp e.LargeIncremen t, aRowNum));
}
}

private bool m_autoScroll;
private InfraControls.E lementList.Elem entsDataGrid m_DataGrid;

[Description("De termines whether the grid will scroll down when a new row
is added."),
Category("Layou t")]
public override bool AutoScroll
{
get { return m_autoScroll; }
set { m_autoScroll = value; }
}

public void SetDataSource(D ataView data)
{
m_DataGrid.Data Source = data;
data.AllowNew = false;
}

private void DoAutoScroll()
{
if( m_autoScroll )
{
m_DataGrid.Scro llToRow((m_Data Grid.DataSource as DataView).Count-1);
}
}

private void AddDefects(obje ct aSender, ArrayList aDefectRows)
{
DoAutoScroll();
}
}

Defects are added to the DataSet, causing the ElementsDataGri d 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
ElementsDataGri d to move --> the focus is taken to the ElementsDataGri d. 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.

Sorry, my latest post was not correct. There is a bug which does not seems
to be of my own code.
