Hi Dave,
You would apply "word-wrap: break-word" on your column style. For example:
Code: HTML/ASPX
<ColumnTemplates>
<eo:StaticColumn>
<CellStyle CssText="word-wrap: break-word"></CellStyle>
</eo:StaticColumn>
</ColumnTemplates>
You would however need to increase ItemHeight property because that one does not automatically increase based on the number of lines, which itself also makes this solution a bit limited.
Thanks
