I'm binding to a grid and I'm getting a weird error when I try to bind a datasource:

This is the statement that causes the error:
RootBindingSource.DataSource = _model;

This is the error:

Value of '1' is not valid for 'Value'. 'Value' must be between 'Minimum' and 'Maximum'.
Parameter name: Value

I can't figure out what is wrong based on the error description.

I added the following statement and it no longer throws the exception:

GridView.MasterGridViewTemplate.AddNewRowPosition = Telerik.WinControls.UI.
PinnedRowPosition.Bottom;

The above is a workaround / hack so it's not really resolved.  I would hope this would go into your defect list to be fixed before the release of Q1.

Also, if I have a read only grid and only have one item in my bindinglist it throws an exception when I bind to the grid.  I have to set AllowAddNewRow to true, bind the grid, then set AllowAddNewRow to false for bindinglists / grids with only one item.

Hello Russell,

Thank you again for your suggestions.

You are right, that this is just a workaround. We added the issues reported by you in our TODO list and they will be addressed in the official Q1 2008 release. We don't have plans to release a second beta before the official release as we're too close to the release date.

Don't hesitate to write me, if you have other questions.

All the best,
Jack

Hello,

I've got the same problem using the current release.
I'm getting this error while populating the Gridview through DataReader.
