DataView Columns

Hi NG,

how to make a DataView show only selected COLUMNS?

E.g:
DataTable table // is already in memory and has two columns: "id" and
"value"
DataView view // should only show all rows from "value"
TIA,
KN

Hi Karl,

Please try this:
MyDataView.Tabl e.Columns.Remov e("ColumnName ")

Thank you, Mike

I have a dataview that is generated from a dataset which gets its data from an xml file. I would like to use the dataview to include only certain columns in the result set. The xml file contains 7 seven columns and I need my dataview to contain only five of them. Is the dataview the right control to do this? Thanks... *** Sent via Developersdex http://www.developersdex.com ***

Hi, I'm developing a webpage with a dataview. The data is retrieved from a database view. The columns in the dataview are created dynamically via a dataset. How can I add special columns like buttons and hyperlinks dynamically to the columns? When using MS Studio Developer you can add these columns via the property builder. In that case the first colums contains the buttons, I want them in the last columns.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
