I have tried the function but it is not working

Page.ClientScript.RegisterOnSubmitStatement(Me.[GetType](), "reload function", "return reloadDocTab();")

Try this:

.aspx

<script type="text/javascript" src="/scripts/visit-flash-report.js"></script>
<asp:Literal runat="server" ID="litJS" />

.cs

litJS.Text = @"<script type='text/javascript'>alert('hello');</script>";

If you dont need to execute the script on a different postback you might want to assign an empty string to the literal.

Do you use a Scriptmanager? Is it a callback or a full postback? – Schadensbegrenzer Jun 19 '14 at 16:15

@user1263981 My bad... I edited my answer. I forgot to add the param "true", so that the script will be added within a script tag. – Schadensbegrenzer Jun 20 '14 at 10:09
@user1263981 When guessing your .aspx structure you would need to insert a placeholder (in this case a literal) after the line where you reference your .js file. See my updated answer for more details – Schadensbegrenzer Jun 22 '14 at 08:52

If I understand what your trying to do. You want to save the record on postback then when the page reloads call the javascript function.

Try this:

PageBody.Attributes.Add("onload", "reloadDocTab()");

no, i don't want to call reloadDocTab() on postback. I want to call it when i click certain button which will save record in DB and then refresh tab. – user1263981 Jun 19 '14 at 15:42

Try one of these:

Page.ClientScript.RegisterStartupScript(this.GetType(), "ScriptKey", "reloadDocTab()", true);

OR

ClientScript.RegisterStartupScript(this.GetType(), "ScriptKey", "reloadDocTab()", true);

OR

ScriptManager.RegisterStartupScript(this.GetType(), "ScriptKey", "reloadDocTab()", true);

And i think you might need to refrence the .JS file in the head tag

<head runat="server">
    <script src="~/scripts/visit-flash-report.js"></script>
</head>
