How to Redirect to new asp page while clicking on the data row of the data grid view in asp.net - asp.net

Question

My data grid view in asp.net displays only selected id from sql server database as a single row.
Now I need to display a particular page when I click on the particular id (data row) and also I want to display all the details in a new page belongs to the selected id (on click on the id).
I have tried this code:
protected void btnserch_Click(object sender, EventArgs e)
{
SqlConnection objsqlconnection = new SqlConnection(CONNECTIONSTRING);
string query = "Select id from registration";
SqlCommand objsqlcommand = new SqlCommand(query, objsqlconnection);
objsqlconnection.Open();
SqlDataAdapter da=new SqlDataAdapter();
DataSet ds=new DataSet();
objsqlcommand.CommandText = query;
objsqlcommand.Connection = objsqlconnection;
da = new SqlDataAdapter(objsqlcommand);
da.Fill(ds);
objsqlcommand.ExecuteNonQuery();
GridView1.DataSource = ds;
GridView1.DataBind();
objsqlconnection.Close();
}
This code returns a grid by selecting only id column from registration table. Now when I click on the data row of the id column, I need an another page which should display all the details belonging to that id.

Answer 1

like #MelanciaUK said "OnItemDataBound" is your friend.
For checking ID even on postback, select it in "SelectedIndexChanging"
hope it helps.

Easiest way to redirect to new page:
<asp:GridView ID="grd" runat="server" autogeneratedcolumn="false">
<asp:TemplateField HaderText="ID">
<ItemTemplate>
<%#Eval("ID")%>
<ItemTemplate>
<asp:TemplateField>
<asp:TemplateField HaderText="Name">
<ItemTemplate>
<%#Eval("ID")%>
<ItemTemplate>
<asp:TemplateField>
<asp:TemplateField HaderText="Edit">
<ItemTemplate>
<a href='Newpage.aspx?ID=<%#Eval("ID")%>'>Edit</a>
<ItemTemplate>
<asp:TemplateField>
<asp:GridView>

Answer 3

You can redirect from one page another page in two ways
<asp:GridView ID="grd" runat="server" autogeneratedcolumn="false">
<asp:TemplateField HaderText="Action">
<ItemTemplate>
<a href='mypage.aspx?ID=<%#Eval("RowID")%>'>Edit</a>
Edit
<ItemTemplate>
<asp:TemplateField>
<asp:GridView>
<script type="text/javascript">
function Redirect(id) {
window.location = 'mypage.aspx?ID=' + id;
}
</script>
