I came across this issue too. Did not like to have to put the OnClientClick=return false on every linkbutton. With a simple page it just easier to use an anchor and avoid asp filling the href in for you.
However this is not always possible. So a Simple conclusion is just to inherit the LinkButton and add a variable like AutoPostBack. if false then just override the output with the html or add the OnClientClick in. I dont really like inline tags.
namespace My.WebControls {
[ToolboxData("<{0}:LinkButton runat=server ID=btn></{0}:LinkButton>"), ParseChildren(true), ToolboxItem(true)]
public class LinkButton : System.Web.UI.WebControls.LinkButton {
private bool _postback = true;
[Bindable(true), Category("Behavior"), DefaultValue(true), Description("Gets or Sets the postback click behavior")]
public bool AutoPostBack { get { return _postback; } set { _postback = value; } }
protected override void Render(System.Web.UI.HtmlTextWriter writer) {
if(!AutoPostBack){
this.OnClientClick = "return false";
}
base.Render(writer);
}
}
}
Many attributes should need to be handled in a ViewState but in this case I think we are good;
