create own style task panel with custom style

Creating a customized style task panel with custom styles in MS-Word using VSTO Word Add-In in C# involves a series of steps. Here's a high-level overview of how you can achieve this:

1. Creating the VSTO Word Add-In Project:

- Start by creating a new VSTO Word Add-In project in Visual Studio.

- Make sure to reference the necessary assemblies for working with Word documents.

2. Adding a Custom Task Pane:

- To create a custom task pane, you can use the `CustomTaskPane` class from the `Microsoft.Office.Tools` namespace.

- Add a user control or a WPF control to serve as the content of your custom task pane.

3. Defining Custom Styles:

- You can define custom styles programmatically by accessing the Word document's `Styles` collection.

- Define the properties of your custom styles such as font, size, color, etc.

- Apply these custom styles to specific content in the Word document using the `Style` property.

4. Sample Code Snippet:

Here is a basic example of creating a custom style and applying it to a range of text in Word using VSTO Add-In in C#:

    // Access the current Word document
    Microsoft.Office.Interop.Word.Document doc = Globals.ThisAddIn.Application.ActiveDocument;

    // Define a new custom style
    Microsoft.Office.Interop.Word.Style customStyle = doc.Styles.Add("CustomStyle", Microsoft.Office.Interop.Word.WdStyleType.wdStyleTypeParagraph);
    customStyle.Font.Name = "Calibri";
    customStyle.Font.Size = 12;
    customStyle.Font.Color = Microsoft.Office.Interop.Word.WdColor.wdColorBlue;

    // Apply the custom style to a range of text
    Microsoft.Office.Interop.Word.Range rng = doc.Range(Start: 0, End: 10);
    rng.set_Style(customStyle);

5. Real-World Application:

- Custom styles and task panes can be beneficial for users who frequently use specific formatting in their documents or need quick access to predefined styles.

- They can streamline the document creation process and ensure consistency in formatting across different documents.

By following these steps and customizing the code to fit your specific requirements, you can successfully create a customized style task panel with custom styles in MS-Word using VSTO Word Add-In in C#.
