C errorprovider validating

Now put this code in your Button1_Click to validate the textbox.Let's say you have a form with textbox control, textbox1.You can display multiple error indications on a form at the same time using the same Error Provider control.

c errorprovider validating-73

Now we need to create validating events for both text boxes.

Right-click on the Text Box then click on "Properties"click on the lightening bolt (Events) icon at the top of the window, then double-click on validating event.

The string specified in the second argument in the function invocation is displayed as the tooltip when the mouse is moved over the Error indicator.

When the user enters data in the controls which fails validation, a blinking error image is displayed on the form next to the control and the error message is displayed as a tooltip to the error image.

You need to set the Data Source, Data Member and Container Control properties of the Error Provider control to set the error for a databound control.

To display the dataset column error, invoke the Set Column Error method of the Error Provider.

EDIT: presently as a work around, I have a method that toggles the "Causes Validation" property on and off. It has to be set on the parent form and suppresses the validating event when a control is losing focus.

I default everything to not Cause Validation, enables them all before I use the event for validating the whole form, and disables them all after again. I think this is the best way to go with validation using Error Provider Component (Or) Try this I've used something along the following lines: 1) Define the controls you want validated in a collection of some sort.

I did find this thing here Counting Error Provider but incase someone knows a better way... Ok so basically I have a Win Form which has many Text Boxes Now when user enters values I use Validating to perform validation and if it does not match Regex I set the Error Provider ON for that Control..

similarly if the user changes the value to a acceptable one I switch Error Provider OFF for that Control..

but when SAVE is clicked i have to do another check anyways incase the user did not listen to me and change the thing like he was supposed to and still clicked SAVE.. soo mm is there like a thing where I could say if Error Providers is not active then proceed with save else message box saying change it.
