Validating event net
Hi Eric There was a good sollution in this newsgroup from Jeffrey Tan, Someone cleaned it up.There stayed another sollution from Jeffrey, describes the problem good, but gives not such a nice sollution. Causes Validation documentation, this property is used for "Gets or sets a value indicating whether the control causes validation to be performed on any controls that require validation when it receives focus." It means that when a disabled control Causes Validation option becomes focused, the validation is not performed on the previous focused control.I am afraid that your goal is not quite clear to me.The values can even be combined with a bitwise OR operation which actually results in a logical AND operation between the individual values.You can choose from: None - validates all child controls Selectable - validates child controls that can be selected Enabled - validates child controls where Enabled is true Visible - validates child controls where Visible is true Tab Stop - validates child controls that have a Tab Stop value Immediate Children - validates child controls that are directly hosted in the container, but not the children of these children One last warning ...
Implicit validation occurs when Auto Validate for the form is set to Enable Prevent Focus Change (the default) or Enable Allow Focus Change. But each control has a Validating and Validated event with a Console. Here's a partial snippet: Private Sub Text Box1_Validating( By Val sender As Object, By Val e As System. In this simple example, the only candidate is the main form. To illustrate the principal, I've coded a call to the Validate method from the Click event of the form.--------Click Here to display the illustration--------(Keep in mind that this only happens when Auto Validate is Disable.)The other Validate overload passes a boolean. NET whether to check the current value of the Auto Validate property. Passing False gives the same result that you get with no parameter at all and results in the Validating and Validated events being triggered.Both Cell Validating and Row Validating events allow you to stop the commit process by setting the boolean property Is Valid to False.
