You can:

* Override [PromptFileNotFound](/api/wisej.web/common-dialogs/wisej.web.filedialog.md#promptfilenotfound). It's called when the specified file doesn't exist and the property [CheckFileExists](/api/wisej.web/common-dialogs/wisej.web.filedialog.md#checkfileexists) is true.
* Override [PromptFileCreate](#promptfilecreate). It's called when the specified file doesn't exist and the property [CreatePrompt](#createprompt) is true.
* Override [PromptFileOverwrite](#promptfileoverwrite). It's called when the specified file doesn't exist and the property [OverwritePrompt](#overwriteprompt) is true.
* Override [CreateUI](/api/wisej.web/common-dialogs/wisej.web.filedialog.md#createui) to create your custom [Form](/api/wisej.web/containers/form.md) when the method [ShowDialog](/api/wisej.web/common-dialogs/wisej.web.commondialog.md#showdialog) is called.
* Set the [DialogTemplate](/api/wisej.web/common-dialogs/wisej.web.commondialog.md#dialogtemplate) to a [Form](/api/wisej.web/containers/form.md) class that has a constructor that accepts [FileDialog](/api/wisej.web/common-dialogs/wisej.web.filedialog.md) as the single argument to change the User Interface (UI) of the file dialog.
* Override [OnFileOk](/api/wisej.web/common-dialogs/wisej.web.filedialog.md#onfileok) to provide your custom implementation of the actions to execute when the user presses the OK button.

You must add at least one [IFileSystemProvider](/api/wisej.core/general/wisej.core.ifilesystemprovider.md) to the [Roots](/api/wisej.web/common-dialogs/wisej.web.filedialog.md#roots) collection before showing the dialog.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wisej.com/api/wisej.web/common-dialogs/wisej.web.savefiledialog.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
