redirection between two pages Asp.net - asp.net

Question

I have a asp.net form with several text boxes and a link-button which is redirected to the other page. here is my form:
<table>
<tr>
<td >
<asp:TextBox ID="TextBox_Name" runat="server" Width="100%"></asp:TextBox>
</td>
<td>
<asp:TextBox ID="TextBox_FatherName" runat="server" Width="100%"></asp:TextBox>
</td>
<td>
<asp:LinkButton ID="LinkButton_BirthPlace" runat="server" OnClick="LinkButton_BirthPlace_Click" >Search</asp:LinkButton> </td>
</tr>
and it is my method for link button :
protected void LinkButton_BirthPlace_Click(object sender, EventArgs e)
{
Response.Redirect("~/Profile/CitySearch.aspx");
}
my problem is: When I enter value in my text boxes and then click on link button , redirected to CitySearch.aspx page and when I come back to base page my values in text boxes were deleted.I need those values that I enterned.
What should I do?

Answer 1

You need to repopulate your textboxes with your information from the Session. Put a method similar to this on your "base page"
Psuedocode:
protected void Page_Load(object sender, EventArgs e)
{
string Birthplace = Session["Birthplace"].ToString();
MyBirthplaceTextBox.Text = Birthplace;
}
You'll need multiple Session values to store multiple pieces of information. You'll also want to code in some checks to make sure your session variables aren't null, and take action accordingly.

Try like This on your First Page:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
if (Session["search"]!=null)
{
TextBox_Name.Text = Session["search"].ToString();
}
}
}

Try like this,
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack==false)
{
if (Session["search"]!=null)
{
TextBox_Name.Text = Session["search"].ToString();
}
}
}
protected void LinkButton_BirthPlace_Click(object sender, EventArgs e)
{
Session["search"] = TextBox_Name.Text;
Response.Redirect("~/Profile/CitySearch.aspx");
}
