Hi

First of all insert the values into the database in the save button click event of first form then in second form you fetch the values from data base to data set  then bind the drop down with the data set values.

there are two ways to pass data between web forms:
 
1. QueryString
2. Session
3. PreviousPage
 
► Using QueryString
 
protected void Button1_Click(object sender, EventArgs e)
{
  Response.Redirect("Default.aspx?name=" + TextBox1.Text);
}
 
protected void Page_Load(object sender, EventArgs e)
{
  string name = Request.QueryString["name"].ToString();
}
 
► Using Session:
 
protected void Button1_Click(object sender, EventArgs e)
{
  Session["name"] = TextBox1.Text;
  Response.Redirect("Default.aspx");
}
 
protected void Page_Load(object sender, EventArgs e)
{
  string name = Session["name"].ToString();
}
 
► Using PreviousPage:

 
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

 
protected void Button1_Click(object sender, EventArgs e)
{
  Response.Redirect("Default.aspx");
}
 
On Default.aspx:
protected void Page_Load(object sender, EventArgs e)
{
  string name = ((TextBox)this.PreviousPage.FindControl("TextBox1")).Text.ToString();
  Response.Write(name);
}

Hello friend,

first of all, i'm not sure where there are any form controls in asp .net either it is page or something else like iframe  but form controls or in windows application anyway, if it is windows application than u can create the object of first form in the second page and fetch the value.


or

if it is a web application than on click of your control simple save the value in database using ado.net, i'm assuming here that u have prior knowledge of ado.net and than on the page_load method of second page u can fetch the value.


let me know in case u need more help on this!!

hi,

You can just use Session and pass the values.I am sure there might be some other way this is simple way to do.


Example

Session("textboxval") = txtbox1.value;

Call this session value on another page as

str = Session("txtboxval")

Thnanks,
