how to update a data table row value to hyperlink?

I have a data table in dt in c# code and it has column[0] datatype is int.So when ever I reach 7th value in the table I need to convert to hyperlink and add it back to data table.

int x = int.Parse(dt.Rows[7][0].ToString());
dt.Row[7][0] = "<a href=\"http:www.google.com\">" + x + "</a>";

but it is givin me the error that can not accept string value to integer. How to over come this?

Correct me I'm wrong. Add an extra column of string type.

dt.Columns.Add("LinkColumn");
...
dt.Rows[7]["LinkColumn"]=string.Format("<a href='#'>{0}</a>",x);

How are you creating the data table? The column has probably been typed to int, so it can not accept string values.

A better way might be to change the data bound control to show the link

protected override void OnInit(EventArgs e) {
    base.OnInit(e);
    DataBound += new EventHandler(GridView1_DataBound);
}

void GridView_RowDataBound(object sender, GridViewRowEventArgs e) {
    GridView gridview = (GridView)sender;
    if (e.Row.RowType == DataControlRowType.DataRow) {
        for (int i = 0; i < gridview.Columns.Count; i++) {
            DataControlField obj1 = gridview.Columns[i];
            if (obj1.GetType() == typeof(BoundField)) {
                BoundField field = (BoundField)obj1;
                string datafield = field.DataField;
                object value = DataBinder.Eval(e.Row.DataItem, datafield);
                Literal c = new Literal();
                c.Text = "";
                e.Row.Cells[i].Controls.Add(c);
            }
        }
    }
}
