asp.net OnClientClick not rendered for initially disabled Button

1582 ワード

Question:
I have a disabled asp.Button, which I enable later with JavaScript. Like this
<asp:Button ID="btnSave" runat="server" Text="Save" Enabled="false" OnClientClick="; return ValidateFields();" OnClick="btnSave_Clicked" />

Answer:
However, the "onclick"method is not rendered as html when the control is disabled. My work around is to add the following code in PageLoad.
btnSave.Attributes["onclick"] = "return ValidateFields();";
