Jan 13, 2017 · Making PDF Viewer in C#.net using Adobe Reader dll file.Duration: 6:54 Posted: Jan 13, 2017 Figure 4 15. Error due to having specified no value for the page parameter How is the MVC Framework supposed to invoke your List() method when it doesn t know what value to supply for page If the parameter were of a reference or nullable type,13 it would just pass null, but int isn t one of those, so it has to throw an error and give up. As an experiment, try changing the URL in your browser to http://localhost:xxxxx/ page=1 or http://localhost:xxxxx/ page=2 (replacing xxxxx with whatever port number was already there). You ll find that it works, and your application will select and display the relevant page of results. That s because when ASP.NET MVC can t find a routing parameter to match an action method parameter (in this case page), it will try to use a query string parameter instead. This is the framework s model binding mechanism, which is explained in detail in 12. Of course, your site still needs to work when somebody visits the root URL without any query string value, so let s define the default page index. how to open pdf file in web browser c#: Upload pdf files in ASP . net - CodeProject c# adobe pdf reader Get image from first page of pdf file - CodeProject

As you ve seen, there are several places to give Drupal information about where your theme, validation, and submission functions are. Having so many options can be confusing, so here s a summary of where Drupal looks, in order, for a theme function, assuming you are using a PHPTemplate-based theme named bluemarine, and you re calling drupal_ get_form('formexample_nameform'). This is, however, dependent upon your hook_theme() implementation. First, if $form['#theme'] has been set to 'foo' in the form definition: 1. 2. 3. 4. 5. themes/bluemarine/foo.tpl.php // Template file provided by theme. formexample/foo.tpl.php // Template file provided by module. bluemarine_foo() // Function provided theme. phptemplate_foo() // Theme function provided by theme engine. theme_foo() // 'theme_' plus the value of $form['#theme']. However, if $form['#theme'] has not been set in the form definition: 1. 2. 3. 4. 5. themes/bluemarine/formexample-nameform.tpl.php // Template provided by theme. formexample/formexample-nameform.tpl.php // Template file provided by module. bluemarine_formexample_nameform() // Theme function provided by theme. phptemplate_formexample_nameform() // Theme function provided by theme engine. theme_formexample_nameform() // 'theme_' plus the form ID. During form validation, a validator for the form is set in this order: 1. A function defined by $form['#validate'] 2. formexample_nameform_validate // Form ID plus 'validate'. And when it s time to look for a function to handle form submittal, Drupal looks for the following: 1. A function defined by $form['#submit'] 2. formexample_nameform_submit // Form ID plus 'submit'. Remember that forms can have multiple validation and submission functions. c# remove text from pdf: iTextSharp Replace Text in existing PDF without loosing formation ... c# winforms pdf viewer control Open PDF File in New Window or New Tab on Button click in ASP .

A nullable type is a type for which null is a valid value. Examples include object, string, System.Nullable<int>, and any class you define. These are held on the heap and referenced via a pointer (which can be set to null). That s not the case with int, DateTime, or any struct, which are held as a block of memory in the stack, so it isn t meaningful to set them to null (there has to be something in that memory space). Drupal has a built-in mechanism for highlighting form elements that fail validation and displaying an error message to the user. Examine the validation function in our example to see it at work: /** * Validate the form. */ function formexample_nameform_validate($form, $form_state) { if ($form_state['values']['user_name'] == 'King Kong') { // We notify the form API that this field has failed validation. how to open pdf file in c# windows application Reading Contents From PDF , Word, Text Files In C# - C# Corner

Rating 3.7 It s very easy to tell ASP.NET MVC what value to use for an action method parameter if no other value is available. Update ProductsController s List() method signature by applying a [DefaultValue] attribute: public ViewResult List([DefaultValue(1)] int page) { // ... method body as before ... } Now if you run the application with no query string values, you ll see the error message has gone, and you ll be shown only the first page of products (as in Figure 4 16). The <isreference> test checks whether the given ID is indeed a valid reference. You can also check whether this ID refers to a certain type of Ant structure. Table 3-12 shows the attribute of the <isreference> element. form_set_error('user_name', t('King Kong is not allowed to use this form.')); } } Note the use of form_set_error(). When King Kong visits our form and types in his name on his giant gorilla keyboard, he sees an error message at the top of the page and the field that contains the error has its contents highlighted in red, as shown in Figure 10-6. c# pdf viewer wpf Open pdf doc in new window MVC4 | The ASP.NET Forums
