Validation - Check validation rules when input focus changesI would like to execute an action (i.e. validate the data of a field) when leaving the field as opposed to validating onSave or onDelete. I know I can make custom contexts for validation - I still cannot figure out how to specify what triggers this custom context, but I know it exists.
I looked at http://www.devexpress.com/Support/Center/e/E449.aspx as well, and it is still unclear how I can handle an event that I would get from most common controls such as a "leave" event.
Hello,
Thank you for contacting us.
As I see, this example already shows how to handle events of underlying controls:
C#void editor_ControlCreated(object sender, EventArgs e) {
// You can access the corresponding property editor control by the following code:
Control editorControl = ((PropertyEditor)sender).Control as Control;
editorControl.HandleCreated += editorControl_HandleCreated;
}
void editorControl_HandleCreated(object sender, EventArgs e) {
// Sometimes it is necessary to access editor's control after it is visible (its handle is created).
((Control)sender).HandleCreated -= editorControl_HandleCreated;
}
You can handle the Leave event there. Then, in your Leave event handler you can validate your custom context.
In addition to the example you found, I suggest you review the Access Editor Settings help article. I hope this helps.
