I have the latest version of the MyraUI Editor working.
However, I have to agree with the other poster who is still not finding any actual C# code generated with the export for the controls created.
Another point that should be taken into consideration and should at least be well documented. The properties provided for the grid in terms of the columns and rows are not labeled properly. To define the number of columns and rows the term parts is used such as with ColumnParts. This makes no sense coming from a professional development background. However, since these are existing properties in the API they should at least be provided with some documentation explaining that these properties are used to define the number of columns and rows that the grid will contain.
Again the terms for the properties that are applied to the controls, which determine where they will be placed in the grid are labeled with suffixes as X and Y. Again, from a professional point of view, this indicates pixels\points in a grid coordinate system or an absolute positioning system for controls on a form. Such terms should have been used with the more meaningful term of index. However, since these terms are already in the API, they should be clearly explained in documentation as to how they related to a cell within the grid.
It took me a while of tinkering with the MyraUI Editor to finally understand how these properties work and realize how necessary they are if one is going to set up a complex interface for the game or simulation.
