![]() To use this approach you should remember to set e.Cancel = true in Validating event of the control when you set an error for control.Īlso to let the user to move between controls even if there is an error, set AutoValidate property of your Form to EnableAllowFocusChange in designer or using code: this.AutoValidate =. It's enough to check ValidateChildren method of your form and if it returned false, it means there is some validation error. You don't need to make the save button disabled. It blocks them into one particular text field. But these events don't allow users to edit their errors whenever they want. AppSettings appset new AppSettings () optionsPropertyGrid. Namespace: Assembly : 22.2. Because of the focus lost.Īnyone has a better idea for this? I have been looking on google and the only things i found was a single validation with the errorprovider, or the event validating. PropertyGrid optionsPropertyGrid new PropertyGrid () optionsPropertyGrid.Size new Size (300, 250) (optionsPropertyGrid) this.Text 'Options Dialog' // Create the class and display in PropertyGrid. DXErrorProvider.SetIconAlignment(Control, ErrorIconAlignment) Method In This Article Declaration Parameters Remarks Specifies the alignment of an error icon for a control.

If (!InputChecks.IsFilledIn(txtFirstname.Text))ĮrrorProvider1.SetError(txtFirstname, "Firstname needs to be filled in!") ĮrrorProvider1.SetError(txtFirstname, "") ![]() So, now the code: private void txtFirstname_Leave(object sender, EventArgs e) Exceptions ArgumentOutOfRangeException The value is less than zero. This because otherwise I noticed you cannot go to another field, until you changed your error. The rate, in milliseconds, at which the error icon should flash. So when there are still errors, the "save" button will keep greyed out or "disabled".īecause I don't want to block my user when he is making an error, and I want him to be able to make the changes whenever he wants im using the event "leave" or on focus lost. Once on the textfields directly, so the user sees that he has made some errors, and once on the button itself. Now I want to have a "double" validation. Im working with errorprovider in a c# winforms application.
