Hi Anguar 2 experts,

I have a question,

In Angular 2, How can we get the user name of the logged in user.

I log in to the windows computer with the network credentials. So how can i get the user name in angular application. If we can directly get user name in angular2. what is the application solution to implement using angular2.

Thanks,

Kiran

hi aamir,

As per my understanding you que is "you have two aspx pages called a.aspx and b.aspx, and a.aspx containing gridview with hyperlink, if any one click on that hyperlink than system will redirect to b.aspx and b.aspx also contain grid view".

If i am right that follow step given below.
1) A.aspx - create grid view with column hyperlink.
 <asp:GridView runat="server" ID="GridView1" ShowFooter="true" AutoGenerateColumns="true">
<Columns>
 <asp:HyperLinkField DataTextField="sname" DataNavigateUrlFields="sid" DataNavigateUrlFormatString="b.aspx?Id={0}"
 ....
</Columns>
...
...
</asp:GridView>

here "DataNavigateUrlFields" pass property name of Id and DataTextField pass property name of Display name and DataNavigateUrlFormatString pass url.
2) now on page load of b.aspx you write your grid bind logic.
3) you can get value selected value of grid row by Request.QueryString["Id"]

hope this will help you.
