Make first and last column not clickable

Question

I have a table being generated in an ASP.net web app. The table has 4 columns. Currently each cell of each row can be clicked to get more detailed info. However, I do not want the first and the last cell in each row to be clickable. How can I make it so that only the first second and third cell can be clicked?

Below is some of the code (from the .cs file):

if(e.Row.RowType == DataControlRowType.DataRow)
         {
            e.Row.BackColor = TRADER_BACKCOLOR;
            e.Row.Cells[0].Font.Bold = true;
            e.Row.Attributes.Add("onmouseover", "style.backgroundColor = 'Silver'");
            e.Row.Attributes.Add("onmouseout", "style.backgroundColor = '" + TRADER_HEX + "'");
            e.Row.Attributes.Add("onclick", "RowClick(this, '" + e.Row.Cells[0].Text + "');");

From the .aspx file:

function RowClick(caller, id)
      {
         if(document.getElementById(id).style.display == "block")
         {
                if(last != "" && parent == id)
                {
                    HideDetailed();
                }
            document.getElementById(id).style.display = "none";
         }
         else
         {
            document.getElementById(id).style.display = "block";
         }
      }

Answer 1

You'll have to know beforehand the count of whatever you are binding your table to for this to work.

// minus one since the RowIndex is 0-based
int total = whateverYouAreBindingTo.Count - 1;

then within your event or whatever it is where you're adding the OnClick event...

if (e.Row.RowIndex > 0 && e.Row.RowIndex < total)
   e.Row.Attributes.Add("onclick", "RowClick(this, '" + e.Row.Cells[0].Text + "');");

Answer 2

I would just not add the attributes for the rows you don't want to be clicked, like:

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

    e.Row.BackColor = TRADER_BACKCOLOR;
    e.Row.Cells[0].Font.Bold = true;
    e.Row.Attributes.Add("onmouseover", "style.backgroundColor = 'Silver'");
    e.Row.Attributes.Add("onmouseout", "style.backgroundColor = '" + TRADER_HEX + "'");
   if (e.Row.RowIndex != 0 && e.Row.RowIndex != yourGridView.Rows.Count - 1)
   {
     e.Row.Attributes.Add("onclick", "RowClick(this, '" + e.Row.Cells[0].Text + "');");
   }
