how to refresh an indiviual user control without refresh entrire page

 

[Hermit Dave]

you can't... user control is rendered as a part of page... if you wish to
just have a particular area refresh. consider using iframe and instead of
user control having a dedicated aspx page which is wound to iframe using src
attribute. you can use the meta tag or client side event based refresh the
page within iframe.

Thanks, Dave.

What about use JavaScript to call PostBack on the control ? Will that work ?

 

[Hermit Dave]

Simply create a public method (example : public void refresh()) where you'll Bind the usercontrol's controls with Datas...
When you need to refresh the user Control call this method ! (in a event for example)

in user control :
public void refresh()
{
DropDownListUsers.DataSource=yourdatesource;
DropDownListUsers.DataBind();
}

And in your Page_Load (in UserControl) you'll have :
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
refresh();
}
}


In the page where you use your UserControl :
protected void ButtonValid_Click(object sender, EventArgs e)
{
YourUserControl1.refresh();
}
