# Step 2 of 6: Set up the C1DynamicHelp control

## Content



In order to associate topics from your Help file with form controls, you must specify the source Help file.

You can do this from the **C1DynamicHelp** **Tasks** menu by setting the [HelpSource](/componentone/api/win/online-dynamichelp/dotnet-framework-api/C1.Win.C1DynamicHelp.4.8/C1.Win.C1DynamicHelp.C1DynamicHelp.HelpSource.html) property to any \*.chm file or NetHelp \*.htm file (use the default.htm or the file name that was used as the base URL for the NetHelp target.). In this example, we will use the **C1Sample.chm** installed with **DynamicHelp for WinForms**, by default.

1.  Click the [C1DynamicHelp](/componentone/api/win/online-dynamichelp/dotnet-framework-api/C1.Win.C1DynamicHelp.4.8/C1.Win.C1DynamicHelp.C1DynamicHelp.html) smart tag (![](https://cdn.mescius.io/document-site-files/images/3b487bec-9ad4-47e0-ad8d-39717dc3c4e1/imagesext/image9_1.png)) to open the **Tasks** menu.
2.  Click the **ellipsis** button next to the HelpSource property.
3.  Locate and select the **C1Sample.chm**. It is located in the Tutorials/Data folder, by default.
4.  Click **Open**.
