Several Ways Redirect to Another Page

Hyperlinks

Performs new request on the target page.
Does not pass current page information to the target page.
Requires user initiation.
Redirects to any page, not just pages in the same Web application.
Enables you to share information between pages using query string or session

state.

Cross-page posting

Posts current page information to the target page.
Makes post information available in the target page.
Requires user initiation.
Redirects to any page, not just pages in the same Web application.
Enables the target page to read public properties of the source page if the pages are in the same Web application.
To pass current page information to the target page (as in multi-page forms).
When navigation should be under user control.

Browser redirect

Performs a new HTTP GET request on the target page.
Passes the query string (if any) to the target page. In Internet Explorer, the size of the query string is limited to 2,048 characters.
Provides programmatic and dynamic control over the target URL and query string.
Enables you to redirect to any page, not just pages in the same Web application.
Enables you to share information between source and target pages using session state.
For conditional navigation, when you want to control the target URL and control when navigation takes place. For example, use this option if the application must determine which page to navigate to based on data provided by the user.

Server transfer

Transfers control to a new page that renders in place of the source page.
Redirects only to target pages that are in the same Web application as the source page.
Enables you to read values and public properties from source page.
Does not update browser information with information about the target page. Pressing the refresh or back buttons in the browser can result in unexpected behavior.
For conditional navigation, when you want to control when navigation takes place and you want access to the context of the source page.
Best used in situations where the URL is hidden from the user.

Detect Javascript is enabled in ASPX programmatically

if (Session["Flag"] == null)
{
Session["Flag"] = "Checked";
string path = Request.Url + "?temp=1";
Page.ClientScript.RegisterStartupScript(this.GetType(), "redirect",
"window.location.href='" + path + "';", true);
}
if (Request.QueryString["temp"] == null)
Response.Write("JavaScript is not enabled.");
else
Response.Write("JavaScript is enabled.");

Could not find the visual SourceSafe internet web service connection information. SourceSafe web service cannot be accessed.

Could not find the visual SourceSafe internet web service connection information. SourceSafe web service cannot be accessed.


Solution:

Visual Studio -> Tools -> options -> Choose Source Control and Plug-in Selection.

Switch Back to Microsoft Visual SourceSafe instead of Microsoft Visual SourceSafe(Interenet);

Multi Language Support

Use Global Resources for your page text and controls based on the user’s language. 

Basics

1. A Resource file(.resx) stores values.
2. Manually indicate that controls should use resources for their property value
3. At run-time, the controls property values are derived from the resource file.

Steps

1. In Solution Explorer, right click the root of your web site , Click Add ASP.NET Folder and then click App_GlobalResources..

             

2. Right-Click the App_GlobalResources folder, and then click Add New Item
3. Choose Resource templates , Name box , type MultiLanguage.resx and click Add.
4. Open the MultiLanguage.resx file
5. First row under the Name column type Login  and Value Column type Login

       6 . Create for resource file for Chinese and Malay language in the name of  MultiLanguage.zh-SG.resx  and MultiLanguage.ms-MY.resx

       7. Enter the all the corresponding values.

Now you have created three values for the resource. At runtime, ASP.Net will read the value based on what language user selected.

     8. Add Label Control to the page

1.    Default.aspx and switch to design mode, drag label control into the page

2.    Right-Click the Label control , click properties and then click the ellipsis(..)button in the expression box.The Expressions dialog box appears

3. In the Bindable Properties list, click Text.

4. In the Expression Type Lost, Select Resources.

5. Expression Properties, Set ClassKey to MultiLanguage and ResourceKey to Username , click Ok.

6. Assign for all Control.

Chinese Link Button Event

Session["Language"] = "zh-SG";

Response.Redirect("Default.aspx");

Malay Link Button Event

  Session["Language"] = "ms-MY";

  Response.Redirect("Default.aspx");

Add the below function in every page

protected override void InitializeCulture()

    {

String str = (String)Session["Language"];

        if (str != null)

        {

            String selectedLanguage = str;

            UICulture = selectedLanguage;

            Culture = selectedLanguage;

            Thread.CurrentThread.CurrentCulture =

                CultureInfo.CreateSpecificCulture(selectedLanguage);

            Thread.CurrentThread.CurrentUICulture = new

                CultureInfo(selectedLanguage);

        }

        else

        {

            base.InitializeCulture();

        }

}

Write the InitializeCulture function in separate file and call that file.
