C rowvalidating Bangalore live sexchatting

Row Cell Style event to highlight cells with values that are wrong initially, not after an end-user has modified them.

Demos: Data Validation | Validate the active editor's value With the row validation feature, the Data Grid delays checking cell values to the point when a user moves focus to another row.

This property can be accessed from the column smart tag.

Behind that is the need to just check the business Object for a property called Is Changed and ask the user to save or discard the changes, before the bindingsource selects the next item.

A repository item is a core from which a full editor can be generated.

For instance, a Repository Item Spin Edit object is the core of a Spin Edit editor.

If you didn't implement this, then you would have to always rebind to your collection, because the grid has no clue when the list has changed (it only knows what it read from the list on hookup). If I add the following below the Remove At call, everything works correctly Grid1. Data Source = my Data Source; I should not have to rebind my datagrid to my datasource.

In Win Forms I could handle the Validated event to do something after the user changed text in a Text Box.

This can be useful when each particular cell is valid, but the entire row with these values is incorrect.
