Hello,

It's possible that certain types of data sources have a way to hide specific fields from the controls to which they are bound. However, I have not personally used any data source with such an option.

By default, UltraGrid will use the fields in the data source to define its schema. You can override this behavior by defining a schema beforehand and telling the grid to use its predefined schema instead of creating a new one from the new data source. Since you already have your data source, you can use it to automatically define the schema first, then bind to the data itself later. In order to do this, take the following steps. I am assuming that you are doing this in the designer and starting with a databound grid:

1. Click the Start! button on the grid or choose Designer Dialog... from the smart tag.
2. Select Data Schema from the tree on the left if it isn't already selected.
3. Click the Manually Define a Schema button.
4. Click Yes to cause the grid to create a schema based off the previously bound data source.
5. Modify the schema if necessary, then click Okay on the Edit Schema dialog.
6. Choose the If you WILL be supplying a DataSource at runtime... option to avoid creating an unneeded data source object.
7. Click OK on the UltraWinGrid Designer form.
8. Add the following code to bind the data without overwriting the schema you set up:

ultraGrid1.DisplayLayout.NewColumnLoadStyle = Infragistics.Win.UltraWinGrid.NewColumnLoadStyle.Hide;
ultraGrid1.DataSource = ultraDataSource1;

Please let me know whether this solution works for you.

I understand we could do that through code.  We have thousands of ultragrids and ultracombos that we setup in design time.  So if your suggestion is the only way to do it, then what is the point of setting everything at design time and getting everything perfect then having to add a new property to an object throws off every grid or combo that we have created based on that object.  It just seems like there should be a way after setting up the grid, that it will lock it to look the way we want.  Is there something simple like adding an attribute to the objects property that tells infragistics to ignore the property.
