Hi Noriko I,

1. Open My Web

2. Select the filter icon on the Last Name column. Unselect "All" and then
select 4 other items

Result => grid is now filtered and shows 4 items but none are selected

Expected Result => After the grid is filtered, I wants the last row in
the grid to be selected.

This is the code I handle for the task:

protected void WebDataGrid1_DataFiltered(object sender, Infragistics.Web.UI.GridControls.FilteredEventArgs e)
{

WebDataGrid1.Behaviors.Selection.SelectedRows.Clear();
if (WebDataGrid1.Rows != null && WebDataGrid1.Rows.Count > 0)
{
WebDataGrid1.Behaviors.Selection.SelectedRows.Add(WebDataGrid1.Rows[WebDataGrid1.Rows.Count - 1]);
}

But last row in the grid is not selected.

How to make last row selected?

Hello Hung Nguyen

Thank you for the clarification.

You might want to set a kind of flag in DataFiltered event and to execute the selection in a later phase, for example, in the PreRender event because of the timing.

private bool _isDataFiltered = false;

protected void WebDataGrid1_DataFiltered(object sender, Infragistics.Web.UI.GridControls.FilteredEventArgs e)
{
    _isDataFiltered = true;
}

protected void WebDataGrid1_PreRender(object sender, EventArgs e)
{
    if (_isDataFiltered)
    {
        WebDataGrid1.Behaviors.Selection.SelectedRows.Clear();
        if (WebDataGrid1.Rows != null && WebDataGrid1.Rows.Count > 0)
        {
            WebDataGrid1.Behaviors.Selection.SelectedRows.Add(WebDataGrid1.Rows[WebDataGrid1.Rows.Count - 1]);
        }
    }
}

Could you try this?
