Show hide Grid column using common function

1 To Hide column in perticular range :

public static void showhide(GridView gv,bool flag,int frmindex,int toindex,bool isfixcolhide,string footertext)

    {

        if (isfixcolhide)

        {

            gv.Columns[frmindex].Visible = flag;

            gv.Columns[frmindex + 1].FooterText = footertext;

        }

        else

        {

            for (int i = frmindex; i <= toindex; i++)

            {

                gv.Columns[i].Visible = flag;

            }

            gv.Columns[toindex + 1].FooterText = footertext;

        }

     

    }

Example:

            To hide Grid column from 1 to 11 as below with show footer text in next column :

                             showhide(gvrf, false, 1, 11, false, "total");

1 To Hide perticular columns using array index :

 

       public static  void showhide(GridView gv, bool flag, int[] index)

        {

            for (int i = 0; i <= index.Length; i++)

            {

                gv.Columns[index[0]].Visible = flag;

            }

        }

Example :  To hide column 1 and 3 as below :

                          int[] x = { 1, 3};

                            showhide(gvrf, false, x);
