How do I open PDF's to specific pages?

Open a PDF to a specific page from a web-server 1. Use name/destination pairs when you Distill your PDF document. Please refer to the https://partners.adobe.com/asn/acrobat/sdk/explodedSDK/Documentation/PDF_Creation_APIs/pdfmarkReference.pdf This is designed for PostScript engineers or for those who are generating their own PostScript. 2. Use a highlight file. 3. append #page=x [where x is the page number]. 4. Select File > Document Properties > Open Options and target the page and view you want. This is the easiest, but least flexible method, as you get exactly one view that you can open to.

How to get the readonly textbox value on the server

In ASP.NET 2.0 and Newer versions , the readonly TextBox will ignore the submitted text , this change due to security reasons . However , assume you have a readonly textbox and you are going to change its value on the client side ( via script) , Now how you will get the changed value on the server side ? One option is to disable the textbox control , and set "SubmitDisabledControls" for the form to true , but this is not always a solution .

UserControls

User Control: User Control is the custom, reusable controls. User Controls offers a way to partition and reuse User Interface (UI) functionality across ASP.NET Applications. Advantages of User Control: • Code Reuse. • Cache the output of the control independently using technique called fragment caching. This will improve performance if used appropriately. • Can program against any properties declared in the control, just like ASP.NET web controls. Disadvantages of User Control: • User Controls can be instantiated in the pages that resides in the same web application. If you want to use across applications, you need to place same .ascx control in each application. • Can't hide code of user controls like server controls by compiling into an assembly. Adding User Controls to an WebForms Page: At the top of the .aspx page, add the below line above tag. <!--Register TagPrefix="Test" TagName="TestControl" Src="Test.ascx"--> This d...
