The best way to handle this is to require that all expected query string parameters have a corresponding strongly typed property (getter only) in the view s code-behind, and return the value as the correct type. If a required parameter has not been passed in or is malformed (i.e., cannot be converted to the required type or contains an invalid value), then it should return a default value or throw an exception. Wrapping the retrieval of a query string parameter in a property this way makes for much cleaner and more maintainable code. For example, the following code is used to handle access to the ProductID parameter. As you can see it returns a typed value (an int), checks to see if the value has been passed in, and then parses out the value. Whenever you need the value of the ProductID parameter, you simply need to reference the ParamProductID property to obtain it. private int ParamProductID { get { int paramValue = 0; const string paramName = "ProductID"; if (NavigationContext.QueryString.ContainsKey(paramName)) int.TryParse(NavigationContext.QueryString[paramName], out paramValue); return paramValue; } } download pdf in c# windows application: Open Source PDF VIewer in Winform - Windows Forms Discussion ... how to retrieve pdf file from database in c# Download pdf Read Online Microsoft Visual C# 2015 : An ... - Issuu

The .wrap() method allows developers to enclose existing elements with one or more new elements quickly and easily. The argument accepted by .wrap() can either be a collection of one or more tags to wrap around the selected elements, or a callback function to generate the tags. First, wrap all the spans in the example document with a strong tag using the following: $("span").wrap("<strong />"); This results in the text of the two spans becoming bold (see Figure 2-8). open pdf and draw c#: C# tutorial: Add annotations to an existing PDF download pdf file from database in asp.net c# save file dialog to download PDF file - C# | The ASP.NET Forums

Figure 2-8. The spans appear bold after wrapping them with strong tags The syntax used for the wrapping element is relatively forgiving, and the output shown in Figure 2-7 could have been accomplished using either "<strong />", "<strong>", or "<strong></strong>". Additionally, multiple tags can be wrapped around elements by passing a nested set of tags to the .wrap() method: $("span").wrap("<strong><em></em></strong>"); After executing the preceding line, the text in the spans will appear bold and italicized (see Figure 2-9). Parallel LINQ (PLINQ) If the entity/object also implements the IDataErrorInfo interface, then the bindings will check the Error/Item properties for any data validation errors corresponding to their bound property, and handle them appropriately In conjunction with the new IDataErrorInfo interface, bindings now have a new property called ValidatesOnDataErrors (whose default value is False), which will treat any errors exposed by the IDataErrorInfo interface as data validation errors You must set this to True on your bindings (even in the DataForm control), or else the controls will not look for validation errors associated with their bound properties (and thus will be unaware of them, and won t restyle themselves accordingly). itextsharp pdf to xml c# Free .NET PDF Library - Visual Studio Marketplace
