DataGrid Default Column Style

[Andrew Armstrong]

I have a datagrid where I want to hide a couple of the columns. To do this I
have added a Table style with two DataGridTextBoxColumn and set their widths
to 0 and MappingName property to the names of the Columns I want to hide.
This achieves the required effect. However when I had a new Column without a
style mapped to it the Column does not appear in the DataGrid. If I am using
TableStyles do I have to define a style for each Column or is there a way of
setting a default style.



I would be grateful for any help or insight into this problem. I am sure it
is possible I just don't know how.



Many Thanks



Andrew

Hi Andrew,

If you defined a TableStyle for a data table, DataGrid will only use the
defined TableStyle to display the datatable. Default table style will not
take effect.
So you need add all the columnstyles needed to the TableStyle object before
adding the tablestyle to the TableStyles collection*.

* as MSDN documentation states:

<cite>
CAUTION Always create DataGridColumnStyle objects and add them to the
GridColumnStylesCollection before adding DataGridTableStyle objects to the
GridTableStylesCollection. When you add an empty DataGridTableStyle to the
collection, DataGridColumnStyle objects are automatically generated for
you. Consequently, an exception will be thrown if you try to add new
DataGridColumnStyle objects with duplicate MappingName values to the
GridColumnStylesCollection.

That clears up what I can and can't do with Table Style's.
