title: Update DataSet in Crystal Reports
body: <p>I have little to no experience in using Datasets and Crystal Reports so please don't bash me if the answer is really obvious, I didn't manage to find the answer on-line.</p>
  
  <p>I have a C# Winforms application, containing a Crystal Report that takes its data from a DataSet. I populate the DataSet dynamically from inside the application.</p>
  
  <p>In the past, if I added another column to the DataSet, I could right click the DataSet in the Crystal Report and click "Verify Database" to make the new columns available in the Report.</p>
  
  <p>Now, if I do this the following window pops up:</p>
  
  <p><img src="https://i.stack.imgur.com/QtQtF.png" alt="enter image description here"></p>
  
  <p>There is no item available in the Class Name combobox, and if I check the checkbox, another combobox appears which is also empty.</p>
  
  <p>Please note that I populate the DataSet from inside the program, so there is no connection. </p>
  
  <p>How can I update the DataSet in the Crystal Reports, so that the new columns become available?</p>
  
  <p>Thank you.</p>
  
  <p>P.S.: I have tried the following solution but it didn't work: <a href="https://stackoverflow.com/questions/4959814/update-dataset-schema-on-crystal-reports-for-vs2008">Update DataSet Schema On Crystal Reports for VS2008</a> because I am presented with the same window as above.</p>

  <p>Edit1: The fields appear in the Data Sources but do not appear in the Field Explorer. </p>
  
  <p>I already have some Formula Fields that have the same name as the newly added Columns but removing them didn't help either.</p>
