We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

To pass pass values using you need to follow the way.

First on the first page you place that value on a page control, I prefer on your case a hidden field, that is also post back to any page.

Then you add your value to that field

ValueHiddenField.value = CellText(dtparent.Rows[0]["UnitName"].ToString())

and you make also a public field so the second page can read it

public string ValueHiddenField
        return ValueHiddenField.value;

And you say to the button to post back to the second page using the PostBackUrl field of the button.

Now this is the way you get your data from second page:
On the redirect page declare what is the previous page on aspx as:

<%@ Reference Page ="~/PreviousPageName.aspx" %>

and on code behind on second page you get the value as:

if (Page.PreviousPage != null)
    if (Page.PreviousPage is PreviousPageClassName)
        Label1.Text = ((PreviousPageClassName)Page.PreviousPage).ValueHiddenField;
        Label1.Text = "no value";
    Label1.Text = "no value from previous page";
