Select next row and previos row

[Jomey]

I have a radgrid with a detailsview.  I added First, next, previous, last buttons on the top manually.   My grid has a GridButtonColumn (select).  When I click the select button i see the details.

When I click the "next" button i want the grid to select the next row and trigger the SelectedIndexChanged event - which triggers the details view.  When I click "previous" - it should select the previous row.

What's the easiest way to do this?  How do i set the rowindex of the grid?

Hi Jomey,

Try the following code snippet to achieve the desired scenario.

CS:

protected void RadGrid2_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "Select")
        {
            GridDataItem item = (GridDataItem)e.Item;
            item.Expanded = true;
        }
        if (e.CommandName == "Next")
        {
            foreach (GridDataItem item in RadGrid2.MasterTableView.Items)
            {
                if (item.Selected)
                {
                    item.Selected = false;
                    item.Expanded = false;
                    int CurrentIndx = item.ItemIndex;
                    int NextIndx = CurrentIndx + 1;
                    RadGrid2.MasterTableView.Items[NextIndx].Selected = true;
                    RadGrid2.MasterTableView.Items[NextIndx].Expanded = true;
                    break;
                }

            }
        }
        else if (e.CommandName == "Previous")
        {
            foreach (GridDataItem item in RadGrid2.MasterTableView.Items)
            {
                if (item.Selected)
                {
                    item.Selected = false;
                    item.Expanded = false;
                    int CurrentIndx = item.ItemIndex;
                    int PrevIndx = CurrentIndx - 1;
                    RadGrid2.MasterTableView.Items[PrevIndx].Selected = true;
                    RadGrid2.MasterTableView.Items[PrevIndx].Expanded = true;
                    break;
                }

            }
        }


    }

thx,

my next question is - since i set a height to my grid - it has vertical scrollbars.  I click the next button until the grid's last item is highlighted - this works.  But the scrollbar doesn't scroll everytime i click the next button. 

I have to manually go to it and scroll to the bottom to see the highlighted item.

Is there a way so the scrollbar automatically scrolls along with clicking the next button?  To focus on the item that is selected.

I tried gvHRD.MasterTableView.Items[NextIndx].Focus();

Hi Jomey,

Here is a help article which explains how to scroll to the selected item in Grid. Go through it and see if it helps to some extent.

This won't work for me because I need it to scroll when I click the next button.

And var scrollArea = RadGrid1.GridDataDiv; is null.

Is there a way to use scrolltop when clicking the next button?
