Remove Gridview row in rowDataBound event asp.net c#

Question

I have a gridview which checks some values on rowDataBound event.I want to remove some rows based on conditions checked in rowDataBound.I tried putting all controls in a Panel and hiding that panel ie,

TRY 1 :

protected void grdFeatured_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //some other codes here
        //IMPLEMENT FILTER ACCORDING TO ABOVE 'VIS' OUTPUT
        if (vis > 0)
        {
            Panel1.Visible = false;
        }
    }
}

PROBLEM :

This messes up the paging since rows are hidden but page count occurs and shows page numbers for the remaining visible rows.

TRY 2 :

protected void grdFeatured_RowDataBound(object sender, GridViewRowEventArgs e)
{
    GridViewRow gvr = e.Row;
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //some other codes here
        //IMPLEMENT FILTER ACCORDING TO ABOVE 'VIS' OUTPUT
        if (vis > 0)
        {
            gvr.Parent.Controls.RemoveAt(gvr.RowIndex);
        }
    }
}

PROBLEM :

gives error :

Specified argument was out of the range of valid values.
Parameter name: index at gvr.Parent.Controls.RemoveAt(gvr.RowIndex);

dont want to edit datasource, help me out guys .

You may have to edit your datasource as page information are calculated from the datasource — codingbiz, Dec 21 '12 at 05:52

row visibility wont affect paging and will mess it. – sajanyamaha Dec 21 '12 at 16:44
Only problem with this approach is that you are gonna have variable page size when you take this approach depending on how many rows get hidden on each page, lol. – drzounds Oct 20 '15 at 19:51
