Question

I want to ask how to pass a variable from a page to another page.

example.

in (page1.aspx.cs) there is button click and textbox

    protected void Button1_Click(object sender, EventArgs e)
    {
        textbox1.text = ;

    }

in (page2.aspx.cs)

A = “hello”
// A is variable that can be change, A variable is coming from microC

What I want is show “hello” from page2 in textbox1.text when I click button1 in page1.aspx

Answer 1

You can pass the value as a querystring parameter.

So if you are using Response.Redirect you could do something like

protected void Button1_Click(object sender, EventArgs e){
    Response.Redirect("Page2.aspx?value=" + taxtbox1.text);
}

On Page 2 you can get the value using Request["value"].ToString()

Notice that the querystring parameter name is what you request. So if you have ?something=else you will Request[“something”]
