Hi,
There is no such built-in functionality.
Though it's possible.
Example
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Ext.NET Example</title>
<script type="text/javascript">
var showPrompt = function () {
Ext.Msg.prompt("Title", "Message");
var d = Ext.Msg.getDialog(),
textEl = d.body.child(".ext-mb-input"),
btnOk = d.buttons[0],
btnCancel = d.buttons[3];
btnOk.disable();
btnCancel.disable();
textEl.on(
"keyup",
function (e, t) {
var disabled = t.value.length < 1;
btnOk.setDisabled(disabled);
btnCancel.setDisabled(disabled);
},
null,
{
buffer : 250
}
);
};
</script>
</head>
<body>
<form runat="server">
<ext:ResourceManager runat="server" />
<ext:Button runat="server" Text="Prompt">
<Listeners>
<Click Fn="showPrompt" />
</Listeners>
</ext:Button>
</form>
</body>
</html>
It might be best to implement your own window to achieve the requirement.
