将值从一页传递到另一个使用按钮或链接和代码？

Question

In asp.net, C#, I actually want 3 conditions on a particular click to delete a record: 1. Ask for confirmation 2. Redirect to another page 3. Pass the id of the record to be deleted internally(not present in any text field or anything) to the next page whose record has to be deleted

If i use a link i an fulfill the 2nd and 3rd condition by using a query string

but if i use a button, then i can fulfill the 1st and 2nd condition.

and in the onclick i redirect it to the next page.

I tried with postback url also, it gives the value 0.

Can anybody tell me what should i use and how so that all the 3 conditions are fulfilled?

Answer 1

Ok i got the answer to this. i simple used this in the onclick event of the button:

string redirect = string.Format("~/Admin-DeleteEmployee.aspx?Id=" + id + ""); Response.Redirect(redirect);

and i can ask for confirmation also and redirect the page along with the value. So all the three conditions are satisfied. Thanx a lot!

Answer 2

If the ID of the record is passed in the ID of the button, you can use something like this when it is clicked

protected void ButtonCliked(object sender, EventArgs e)
{

    string buttonID = "";
    if (sender is Button)
    {
        buttonID = ((Button)sender).ClientID;

        string url = "RedirectUrl.aspx?buttonID=" + buttonID;
        Response.Redirect(url);
    }
}

Hope this helps.
