Not to clear textbox on page reload or button click event

Question

I have developed a website in C# asp.net which contains a Master Page. I have designed a top menu with Search bar(txtSearch) and a Button(LinkButton). When I click on search Button it redirects to the page where searched data is to be displayed but when it redirects it clear's the txtSearch. What I want is not to clear the txtSearch on page redirect or page reload.

Top Menu (Search bar)

<asp:TextBox runat="server" ID="txtSearch" TextMode="SingleLine" CssClass="form-control" Placeholder="Search term..." />
<span class="input-group-btn">
    <asp:LinkButton runat="server" ID="btnSearch" CssClass="btn btn-default" type="button" OnClick="btnSearch_Click"><span class="glyphicon glyphicon-search"></span></asp:LinkButton>
</span>

I Hope that the question is clear.

What you can do is.. Store the TextBox value in Session in onclick() Function

protected void btnSubmit_Click(object sender, EventArgs e)
{
   Session["TextBoxVal"] = TextBox1.Text;//The particular TextBox that has value
}

and onPageLoad just assign the value to the TextBox value like this

 protected void Page_Load(object sender, EventArgs e)
    {
       if (!IsPostBack)
       {
            TextBox1.Text = (string)ViewState["TextBoxVal"];
       }
         //use this as per your needs just an example how to use
        if(IsPostBack)
        {
            TextBox1.Text = (string)ViewState["TextBoxVal"];
        }
    }

and once it is assigned value to the TexBox clear the session or it will keep assigning the same value.. do it like this

Session["TextBoxVal"] = null;

How to add that that value back to txtSearch(of master page) from Search.aspx page ? @Frost_Mourne – Jay Patel Jun 27 '17 at 07:02
Same TextBox1.Text = (string)ViewState["TextBoxVal"]; session can be used in any page of the Solution. just give the proper TextBox Id and u can use it – Frost_Mourne Jun 27 '17 at 07:03
I know that Session value can be retrieved in any page but how to retrieve the textbox(txtSearch of Master Page) ?? – Jay Patel Jun 27 '17 at 07:04
(string)ViewState["TextBoxVal"]; this just gives u the string which u previously saved u can give it to everything that can hold data u can give it to even label.Text= (string)ViewState["TextBoxVal"]; or anyother element – Frost_Mourne Jun 27 '17 at 07:10

You must pass value in querystring in between pages to persist it.
