Answer:
lets take an example what you want simply when user see her/his mail then after clicking the mail the row color is chage . Exactly we want this in your project .. So there are a solution ..
write the following code on your child window page laod  or where you want

const string cRefreshParent = "<script language='javascript'>" +

    "  window.opener.document.forms(0).submit();" + "</script>";

    const string cRefreshParentKey = "RefreshParentKey";

    if (!this.Page.ClientScript.IsClientScriptBlockRegistered(cRefreshParentKey))

    {

        this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(),

        cRefreshParentKey, cRefreshParent);

    }

I think   this solution is quite easy but very useful if you want to create Web applications in which  open child window and you want to refersh parent page.
