 Posted: Tue Jul 12, 2005 8:23 am Post subject: UniversalEditBox and Strongly Typed DataSet |
 |
|
Hello Support
I have a Strongy Typed DataSet bound to a Virtual Tree. Some (String)Cells are editable through a UniversalEditBox.
If the Cell contains null, it's not possible to type Text inside the UniversalEditBox (like http://www.infralution.com/phpBB2/viewtopic.php?t=47).
I suppose that the UniversalEditBox can't be associated to a TypeConverter beacause the Data inside the cell is null.
Why can't the UniversalEditBox take the right DataType-Information from the Typed Row?
Thanks and Best Regards
Giuseppe |

The answer is it probably should. ObjectCellBindings do pass the type information from properties to the editor (via CellData) - however the DataRowCellBindings currently omit this - we will fix this in the next scheduled minor release (1 to 2 weeks away).
In the meantime if you desperately need this you could override the GetCellData method/event and set the CellData.TypeConverter and CellData.TypeEditor properties for the specific columns that are a problem.

Another thought. What is the data type in the column you want to edit?
If the column you are having a problem with is a string type then you probably should simply change to use a simple TextBox as an editor for this column. You don't really need the versatility of the UniversalEditBox for strings and using a simple text box has no issues with null fields.

I want implement a Generic behaviour (for this purpose, the UniversalEditbox is very great) . The string type was just an example.
thanks again

Version 1.6.1 (just released) will now pick up the TypeConverter from the table column DataType allowing you to use an UniversalEditBox as an editor even the column contains DBNulls.
