How to show selected record from grid view to another page?

In this article I have explained about how to show selected record details from grid view into another page one page. In the second page we update the selected Record details. This article I used to transfer a primary key value using Query String option.

Grid view is used to display records from database some time we need to edit that data instead of grid view edit option we want to send that details another page and update that record values from that values. So I used the Link Button in the grid view for show user Identity Primary key value if user click that link button I send that value as query string to another page.

How to send selected record ID field as query string?
Here I used GridView1_RowCommand event for send user selected record identity value.I check that user command event use of "e.CommandName" if match command value then redirect to another page.
Below code is send value through query string

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
if (e.CommandName == "cmdBind")
LinkButton lb = (LinkButton)e.CommandSource;

Response.Redirect("Default2.aspx?sid=" + lb.Text + "");


How to get query string value ?
You can get query string value in another page (redirected page) Page_load event.

if (!Page.IsPostBack)
String sid = Request.QueryString["sid"];
if (sid == "")
Response.Write("Invalid Student ID");
sqlcmd = new SqlCommand("select * from stud where sid='" + sid + "'", sqlcon);
da = new SqlDataAdapter(sqlcmd);
if (dt.Rows.Count > 0)
TextBox1.Text = sid;
TextBox2.Text = dt.Rows[0][1].ToString();
TextBox3.Text = dt.Rows[0][2].ToString();

Source Code Detail:

    my requirement is select an item in gridview and navigate to another page with use of QueryString where i can get the complete costmer details from the db using query string user id

    No. of ways we can do this. In that one of the best way is use HyperLinkField template of gridview and use DataNavigateUrlFields property to pass parameters from one page to another page.

    Use below sample to achieve our goal

    asp:HyperLinkField Text="View" DataNavigateUrlFields="CL_Id,CL_Desc,CL_Short_Desc" DataNavigateUrlFormatString="~/_Layouts/DMS/ChecklistItems.aspx?CL_Id={0}&CL_Desc={1}&CL_Short_Desc={2}"

    and in page2, you just call that parameters using QueryString.

    string CL_Id="",CL_Desc="",CL_Short_Desc="";

    if( Request.QueryString["CL_Id"] != null)
    CL_Id = Request.QueryString["CL_Id"].ToString();

    if( Request.QueryString["CL_Desc"] != null)
    CL_Desc= Request.QueryString["CL_Desc"].ToString();

    if( Request.QueryString["CL_Short_Desc"] != null)
    CL_Short_Desc= Request.QueryString["CL_Short_Desc"].ToString();

    we can able to pass the values like above.

    i think the best and easy way to pass Gridview Parameters to another page using HyperLinkField.

    Hope this will help you someone else those who are looking for the same.
