ScrollIntoView

[Phillip Garrett]

Hi,

Using ScrollIntoView with SelectedItem always places the selected row at the bottom of the visible grid. Is there a way to have the SelectedItem appear at the top of the visible grid after scrolling into view?

Thanks,

Phill

Hello Phillip Garrett,

This is the default behavior of RadGridView by design . Still it is possible to achieve what you request , but it will involve some pretty  ugly hacks . Let me know in case you decide to go that way and I will try to prepare a small sample for you.

Please can you show me the ugly hack :)
Thanks,

Hi Phillip Garrett,

Here you are:

private void ScrollItemToTop(int itemIndex)
        {
            this.RadGridView1.ScrollIntoViewAsync(this.RadGridView1.Items[RadGridView1.Items.Count - 1],
                        f =>
                        {
                            this.RadGridView1.ScrollIntoView(this.RadGridView1.Items[itemIndex]);
                        }

                        );
        }

This method will scroll the Item intto view and place it on the top.

The hack is based on the fact that if the Item comes from above the view port is always placed at the top . So what we actually do is - first scroll to the end , then scroll to the item .
The result - the item finally is on top.

How would you convert this

rgvJobs.SelectedItem = Job;

rgvJobs.ScrollIntoView(Job);

Into this :

rgvJobs.ScrollIntoViewAsync(Job, f =>

{

 

 

    // What do I put here ?

 

});

Hi Marc Roussel,

This should work:

rgvJobs.ScrollIntoViewAsync(Job, f =>
{
   rgvjobs.ScrollIntoView(Job);

});
