I am working on bringing applications with older components to the 2020.1 fold .. I have the following problem that I need to resolve.
On one hierarchical grid there is a need to format cells as the underlying data is floating point but only one row actually need to show decimals while the rest of the data should be whole numbers…. In an old application that was addressed by assigning delegate to the GridView.Columns[i].FormatFieldMethod that actually return the correct formatting string. It worked fine.. In new components it blows up if data on the grid was updated… If you can have a look and advise how to address the issue.
Here steps to recreate :
2. Click Post button, page get reposted, all the same.
3. Change some value in the a5 or a6 column on the main grid. It blows up, as somehow the lr4whdg reference is not there .. it also skips lr4whdg_RowUpdating event.. It does not skip it and works fine if data on the child grid updated..
