Access variables after initialization in page load ASP.NET Webforms-CodePudding

I have this webform:

public class web1{
    private string target = string.Empty;

    protected void Page_Load(object sender, EventsArgs e){
        target = "something";
    }

    protected void btnSubmit_Click(object sender, EventArgs e){
        //use target variable here
    }
}

When I click the button which triggers btnSubmit_Click() the target variable gets reset to string.Empty because of private string target = string.Empty.

Currently I'm assigning the new value to a Session and clearing it after the button click, but was wondering if there was a way of avoiding Session.

CodePudding user response：

This typcial would work:

private string target = string.Empty;

protected void Page_Load(object sender, EventsArgs e){
    if (!IsPostBack) 
    {
        target = "something";
        ViewState["target"] = target;
    }
    else
        target = (string)ViewState["target"]; 
}

Now any button click, event code, or whatever is free to use target.
