i have used runtime checkbox in gridview.Below is my code for that.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
       {
           if (e.Row.RowType == DataControlRowType.Header)
           {

           }

           if (e.Row.RowType == DataControlRowType.DataRow)
           {
               int i = Convert.ToInt16(ViewState["i"]);
               CheckBox chk = new CheckBox();
               chk.ID = "DynamicCheckBox" + e.Row.Cells[0].Text;
               //chk.Text = e.Row.Cells[3].Text;
               e.Row.Cells[0].Controls.Add(chk);
           }
       }

C#

foreach (GridViewRow grdRow in GridView1.Rows)
{
    if (((CheckBox)grdRow.FindControl("DynamicCheckBox" +grdRow.Cells[0].Text)).Checked)
    { 
          // do something
     }
}

You can add a jquery click handler for the button.

XML

<pre lang="Javascript">
$('#button').click(function(){
   $('[^=DynamicCheckBox]').each(function(){
      if($(this).is(':checked'){
      //add the attribute of checkbox(you want -- can be the row idx) to a hidden field with a delimiter
      }
   });
});

</pre>

Then in the code behind in button click event split the hidden fields value
and get the values you want
