Disable hyperlink if cell value null in gridview

Question

I have a grid where columns are populated dynamically. I have a column called ID which will have hyperlink enabled and hyperlinks needs to be disabled if cells value is null or empty.

 

Code: 

 

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

{

if (e.Row.RowType == DataControlRowType.DataRow)

{

for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)

{

string strHeaderRow = GridView1.HeaderRow.Cells[i].Text;

if (strHeaderRow == "ID")

{

string strMktURL = "http://www.address.com";

HyperLink hlColumns = AddHyperLink(e.Row.Cells[i], strMktURL);

}

}

}

}

protected HyperLink AddHyperLink(TableCell cell, string strURL)

{

HyperLink hl = new HyperLink();

hl.Text = cell.Text;

hl.Font.Underline = true;

hl.Target = "_blank";

hl.NavigateUrl = strURL;

hl.Attributes.Add("style", "color:Black;");

cell.Controls.Add(hl);

return hl;

}

 

Please suggest how this can be achieved.
