Visual Studio Tips &Tricks : 3 – Ctrl+, - File Search Easy

By Francis   Posted at   11:28 AM   Visual Studio Tips and Tricks No comments
                 Whenever the project grows large it’s hard to take the necessary file in Visual studio. That is we need to traverse a lot of folders or sub folders if we know the file where it was exactly. 

                  Sometimes, when you deployed in a new project, if another user just mention a file name and ask you take a look about particular logic its really painful to find that file where it was located exactly.

                   At these times the hot key combination Ctrl + , (Control Key with Semicolon) comes a handy. Which opens “Navigate To” window in which if we started type it will list down the file name in a quicker manner. So that we can pick up the file easily.
Navigate To - Window 

                   It not only listed the File names, it also list down the method name too. So whether you search a method or File use the 
shortcut key Ctrl+, and navigate quicker.

Please give your valuable comments which improves my future articles!

Access ASP.Net Server Control in Client Side Using Javascript

By Francis   Posted at   12:18 PM   Client ID in ASP.Net No comments
              Some time, we have a situation to access the server side ASP.Net controls and its values using Client side script like java script.  In this post I’m going to explain how to do that with a simple example.

A word about Client ID:

              As all of us know, that server side controls are submitted and processed by the ASP.Net engine, which emits the respective HTML to the browser. At that time the ASP.Net engine takes the server controls and provide ID (which can be varied across asp.net versions) for it.

            Consider the below example, which has 3 text boxes, after entered values in first 2 text boxes when the user clicks the button then javascript function called which will add the values and put it in 3rd text box. These controls are Server controls.

 
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
        function Add() {
            var intFirstNo = document.getElementById("<%= txtFirstNo.ClientID %>").value;
            var intSecondNo = document.getElementById("<%= txtSecondNo.ClientID %>").value;
            var intResult = parseInt(intFirstNo)  +  parseInt(intSecondNo);
            document.getElementById("<%= txtResult.ClientID %>").value = intResult;
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <table>
<tr>
            <td>
                Enter First Number:
            </td>
            <td>
                <asp:textbox clientidmode="Predictable" id="txtFirstNo" runat="server"></asp:textbox>
            </td>
        </tr>
<tr>
            <td>
                Enter Second Numer:
            </td>
            <td>
                <asp:textbox id="txtSecondNo" runat="server"></asp:textbox>
            </td>
        </tr>
<tr>
            <td>
                Addition is:
            </td>
            <td>
                <asp:textbox id="txtResult" runat="server"></asp:textbox>
            </td>
        </tr>
<tr>
        <td align="center" colspan="2">
        <asp:button id="btnResult" onclientclick="Add(); return false;" runat="server" text="Calculate">
        </asp:button></td>
        </tr>
</table>
</form>
</body>
</html>
Consider this java script line:

 
var intFirstNo = document.getElementById("<%= txtFirstNo.ClientID %>").value;

                When the above line is read by the ASP.Net engine, it will search the Server control ID “txtFirstNo” and get the respective client ID, which has been assigned by ASP.Net engine.  In other words, ASP.Net get the Client ID for that Server control “txtFirstNo” and substitute there in between the double quotes. As a result when we saw the view source of the page we can read that above one as follows:

var intFirstNo = document.getElementById("txtFirstNo").value;

We also return false (in line no 42) after call the javascript function "Add" to avoid the postback when we click the button.

 Just copy the above sample in a webform and try it yourself!

Work Around: Break Point Not Hitting in Visual Studio

By Francis   Posted at   11:14 AM   Visual Studio No comments
                In my professional experience with Visual studio sometimes break point doesn’t hit when we attached to the Worker process. It just tells that Symbols are not loaded.

                 The below are the possible workaround to solve this problem (Try it one by one in this case):
  1. Clean and Rebuild the Solution/Project.
  2. Close all the windows using Window -> “Close All Documents” and restart the Visual Studio. Then Build/Rebuild the Solution/Project.
  3. Go to the Temporary Folder (which is available in the .Net Framework installed Location) and clean the Temporary files of that Solution/Project. Kill the worker process and rebuild the solution.
Hope this helps a bit!

Visual Studio Tips & Tricks: 2 – Create Virtual Directory Problem

By Francis   Posted at   12:15 PM   Visual Studio Tips and Tricks No comments
                     Few days ago, I just want to create a virtual directory for my ASP.Net web project. I just go to the “Solution Explorer” and “Right click” on the Web project in the floating menu choose the “Properties” of the Web project.

Project Properties Float Menu

              In the Properties page, Select “Web” Tab and select the option “Use Local IIS web Server” and then click “Create Virtual Directory” button. At that time the below error occurred:

Unable to create the virtual directory. To access local IIS Web sites, you must run Visual Studio in the context of an administrator account.
