How to change ASP.NET CheckBox control Enabled property using javascript. bug or behavior?

31 בדצמבר 2008

Changing status to enabled\disabled for regular input type checkbox in javascript is very simple. You just need to use the javascript code:var checkBox = document.getElementById("chkToTest"); checkBox.disabled = true\false; Well try to use this javascript code above on ASP.NET checkbox web control when you set the server side Enabled property to false like below: chkToTest.Enabled = false; I'm telling you it will not work!!!!

Architecture Question Use ADO.NET Sync Framework Or Other Solution

24 בדצמבר 2008

היי, יש לי התלבטות איך לממש משהו מסויים וחשבתי אולי ללכת על פיתרון של:  Sync Framework of ADO.NET.   הדרישה בגדול היא לתת ליוזרים לעדכן נתונים במערכת ובזמן מסויים לאחר בדיקות תקינות של הנתונים לעלות אותם למערכת האמיתית של PRODUCTION בצורה אוטומטית. האפליקציה כנראה תהיה ASP.NET על שרת IIS. חשבתי שה-DB שה-ASP.NET יעדכן יהיה ה-DB הזמני וכאשר יוזר יחליט שהמידע תקין ומתאים לו הוא יוכל להעביר אותו ל-DB האמיתי ע"י לחיצה על כפתור או כל דרך אחרת.   מעניין אותי לדעת מה אתם חושבים? איך הייתם מממשים דבר כזה? האם לפי הניסיון שלכם התשתית SYNC של ADO יכולה לתת לי מענה ברמה של: ביצועים סבירים, תמיכה בסינכרון של מספר טבלאות עם קשרים בניהם (קשרים...

How to Modifies code generation for just-in-time (JIT) using code

23 בדצמבר 2008

Hi all, Did you know that you can control JIT code generation using code? Well you can. You can use the .NET DebuggableAttribute. The DebuggableAttribute controls how the runtime treats code within the module. The runtime might track extra information about generated code, and it might disable certain optimizations based on the values contained within this attribute. How to use: On your AssembllyInfo.cs file you can add the code: First boolean (IsJITTrackingEnabled) - Gets a value that indicates whether the runtime will track information during code generation for the debugger. Second boolean (IsJITOptimizerDisabled) - Gets a value that indicates whether the runtime optimizer...

Cross site Ajax plugin for Prototype

2 בדצמבר 2008

Thierry Schellenbach has implemented a Prototype plugin that allows you to do cross site remoting using the dynamic script tag method that other frameworks such as Dojo and jQuery have supported for awhile.You can implement this by simply setting crossSite: true as a config parameter to Ajax.Request.Code example:new Ajax.Request('myurl', {method: 'GET',crossSite: true,parameters: Form.serialize(obj),onLoading: function() {//things to do at the start},onSuccess: function(transport) {//things to do when everything goes well},onFailure: function(transport) {//things to do when we encounter a failure}});the full information can be found on Thierry Schellenbach blog
