Forms Data Controls :: Make Specific Cells In A Dynamic Gridview Clickable And Capture The Cell Info Before Redirecting

I generate dynamic grids based on a count value returned from some DB tables. the code for it goes like this : I give and Id to each grid that is generated.

if (myDataList1.Count >= 1)
{
for (int i = 0; i < myDataList1.Count; i++)
{
//retrieving the exact i count from pageload
ViewState.Add("newCount", i);
//creating the dynamic grid with its corresponding gridview properties.
grvDynamic = new GridView();
grvDynamic.ID = "GridView" + (i+3);
grvDynamic.AutoGenerateColumns = false;
grvDynamic.RowCreated += GridViewRowCreated;
grvDynamic.RowDataBound += grvDynamic_RowDataBound;
//adding bound field columns to retrieve data from stored proc
BoundField metric = new BoundField();
metric.HeaderText = "Goal ";
metric.DataField = "metric";
grvDynamic.Columns.Add(metric);
BoundField mtd = new BoundField();
mtd.HeaderText = "MTD";
mtd.DataField = "value_MTD";
grvDynamic.Columns.Add(mtd);
BoundField goal = new BoundField();
goal.HeaderText = "Tier Level Achieved";
goal.DataField = "value_goal";
goal.HeaderStyle.Width = Unit.Percentage(10);
grvDynamic.Columns.Add(goal);
BoundField you1 = new BoundField();
you1.HeaderText = "Month End";
you1.DataField = "firstLevel_you";
grvDynamic.Columns.Add(you1);
BoundField you2 = new BoundField();
you2.HeaderText = "Month End";
you2.DataField = "secondLevel_you";
grvDynamic.Columns.Add(you2);
ButtonField singleClick = new ButtonField();
singleClick.CommandName = "clickHyperlink";
singleClick.Visible = false;
grvDynamic.Columns.Add(singleClick);
BoundField metricId = new BoundField();
metricId.HeaderText = "Metric Id";
metricId.DataField = "metricID";
metricId.Visible = true;
grvDynamic.Columns.Add(metricId);
//binding the gridview to data.
grvDynamic.DataSource = data;
grvDynamic.DataBind();
grvDynamic.Columns[5].Visible = false;
}
}

protected void grvDynamic_RowDataBound(object sender, GridViewRowEventArgs e)
{
//this basically gets the metric Id's of rows with the ishyperlink flag set to 'Y'. I need to make these particular cells clickable var isClickable = (from md in myDataList3 where md.IsHyperLinkFlag == 'Y' &&

md.value_MTD != null select md.metricID).ToList();
if (e.Row.RowType == DataControlRowType.DataRow)
{
// Get reference to button field in the gridview.
LinkButton _singleClickButton = (LinkButton)e.Row.Cells[5].Controls[0];

if (isClickable.Contains(Convert.ToInt32(e.Row.Cells[6].Text)))
{
e.Row.Cells[1].Style["cursor"] = "hand";
e.Row.Cells[1].Style["color"] = "blue";
e.Row.Cells[1].Style["textdecoration"] = "Underline";
e.Row.Cells[1].Attributes.Add("onClick", "window.location ='../HeaderPages/page2.aspx' ");
}
}
}

This code works perfectly fine , depending on the ishyperlink flag in the database...specific cells in the grid are made clickable and then redirected to page2.aspx My Issue: I need to capture which specific cell in which specific grid the user has clicked. store some information in sessions based on the cell clicked and use that information in page2.aspx.
