Confirmation before the event fire

The purpose of Attributes

---

In asp.net one of the main control is command Button. My scenario is display the confirmation before the event fire. Let we see


It’s simple

Use JavaScript function “confirm”.

Syntax:

[controls]. Attributes.Add(strkeys as string , values as string)


Code :


btnExit.Attributes.Add("OnClick","return confirm('Exit from this Page')");

btnExit – Command Button
Attributes- basic control Attributes( HTML controls or Client controls)
So when you add an Attributes its fire on the Client side without server requst
OnClick- Event Name . Not only the events css also
Confirm- JavaAcript

Example or Events:

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
// set the Attributes at the time of form loading

btnExit.Attributes..Add("OnClick","return confirm('Exit from this Page')");
}
}



Another one Example with CSS :

protected void grdRackingmaster_RowDataBound(object sender, GridViewRowEventArgs e)
{

// set the row background color of the gridview at the time of DataBound event

if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onmousemove", "this.style.backgroundColor='#D1D9E5'");


e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=''");

}

}

- when the mouse moves on the gridview control row color changed

Result :
