Visual Studio Macros and Build Events

Visual studio has a nifty feature called Post/Pre Build events. These are used to include extra Dos commands and Macros and execute them before or after build.

You can open it using project properties and it will open dialog as shown below:

BuildEvent Dialog

For post-build events you can define when to run commands included as shown in below snap:

Post-build events

You can click the respective Edit build buttons and it will open popup as shown below:

Build Popup

By clicking the Macro button it will open macro listing and their respective value.

By using Macros and dos command you can copy files from one location to another and run batch files and so on. In my current project I do have below command to copy xml file and email templates from common code project to my solution directory:

RD "$(SolutionDir)WebAdmin\XML"
MD "$(SolutionDir)WebAdmin\XML"
COPY "$(ProjectDir)XML" "$(SolutionDir)WebAdmin\XML"

RD "$(SolutionDir)WebAdmin\EmailTemplates"
MD "$(SolutionDir)WebAdmin\EmailTemplates"
COPY "$(ProjectDir)EmailTemplates" "$(SolutionDir)WebAdmin\EmailTemplates"

In above code, $(SolutionDir) and $(ProjectDir) are macro names. Macros are non case-sensitive. Check out this link that shows macros along with their descriptions.

Use this nifty feature and automate your tasks Smile

Reset .net validation controls client side

On many occasions we provide form reset functionality and people handle it client side or server side. In general we validate input from the user and show proper validation message. But sometimes it happens that user has entered wrong input and thus it will display validation messages. Now if you have handled form reset functionality client side, you must reset all validation message as well. You can do it as shown in below code:

  function ResetForm() {
            $('input[type=text], textarea').val('');
            return false;

        function Page_ClientValidateReset() {
            if (typeof (Page_Validators) != "undefined") {
                for (var i = 0; i < Page_Validators.length; i++) {
                    var validator = Page_Validators[i];
                    validator.isvalid = true;

 <asp:Button ID="btnReset" runat="server" Text="Reset" OnClientClick="return ResetForm();" />

Now let’s understand what JavaScript properties and functions are.

Page_Validators : This is an array containing all of the validators on the page.

isvalid: This is a property on each client validator indicating whether it is currently valid.

ValidatorUpdateDisplay: Inbuilt function which checks whether validation control’s display property is set to dynamic, if yes then it will set css style of that validator to none.

So basically it loops through all the validators, set isvalid property to true and set validators’s visibility to none. Here we're not using form reset funtction to clear form fields as Reset doesn't clear a form, it simply sets the form value to their default which may or may not be blank. 

I hope it helps!
