C#

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

C#

string primaryKey = DataBinder.Eval(e.Row.DataItem, "Entry_No") + "";

C#

if (e.Row.DataItem == primarykey)
           {
               e.Row.BackColor = System.Drawing.Color.Blue;

Hi Jack.

You can try like this.

1) After getting the primary key from gridview using javascript, you can pass the primarykey as query string in the url
example ( window.location = ' your url.aspx?Key='your key' )

2) And in the page load method you can check the query string for that particular key as below.

C#

string _primaryKey = "";
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                _primaryKey = Request.QueryString["key"];
            }
        }

        protected void GridViewJobList_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                string primaryKey = DataBinder.Eval(e.Row.DataItem, "Entry_No") + "";
                if (primaryKey == _primaryKey)
                    e.Row.BackColor = System.Drawing.Color.Blue;
            }
        }
