RadBindingNavigator is a familiar looking navigation control that allows the user to move between objects in an underlying data source, as well as initiate the creation of a new object, or delete an existing one. RadBindingNavigator is another new control being introduced in Q1 2014. Since when will I ever need to edit and maintain a single object? What do I do when I’m working with a collection of data and I need to move between records in my form? Luckily Telerik UI for WinForms has you covered in this scenario as well. RadDataEntry also has ErrorProvider support as well as an integrated validation panel where you can conveniently display any error messages. A rich event model gives you even more flexibility where you can include things like data validation or swap out an automatically generated editor. You can specify how many columns of fields you want to have displayed as well as other visual attributes like the width of the data entry controls and the directional flow of the form.
Turn errorprovider off full#
On top of this, you retain full control over how the form gets rendered. RadDataEntry handles the CRUD (Create, Read, Update, Delete) to the data source automatically. You no longer have to painstakingly lay out simple data entry forms, let this control take care of this for you. This versatile control will save you loads of time by automatically generating a data entry form based on an underlying data source. RadDataEntry makes its entrance to the UI for WinForms control suite. New Controls Simplifying Data Entry with RadDataEntry Let’s take a quick look at what this release has to offer. The Q1 2014 release of UI for WinForms is packed with some great new controls and cool new features. I found an appropriate regex here and the following will validate your email text box for you (note I've set the email text to lower case to allow for a simpler regex - always a good idea in my opinion). Next - as per my comment, there is no need to turn autovalidation off while you are validating - it sort of defeats the purpose :-) The correct way to let the system know that the validation has failed is to use the CancelEventArgs parameter provided - i.e. Let's deal with TxtEmail_Validating first.Īll those checks that could finally lead to the message "Email cannot be left blank" are a waste of time - if you choose an appropriate regex to test against.īut if you were going to leave them in, you need to exit appropriately once you have discovered that the validation has failed.Īlso there is no need to set the focus to the control that you are validating because you have not yet left that control.įinally, you went to all the trouble of trimming the text in the textbox, but didn't use it when matching to the regex.
Turn errorprovider off password#
In the case of Password Validation.Even after entering password as per the parameters within the Regex,it throws "Invalid Password" message.I saw questions here based on validation but none of them have satisfactory solution to my question.Ĭan anyone help me to rectify this error? I want to achieve Validation without ErrorProvider which is another option.
But when I remove the text within the texbox and re-enter it, validation doesn't work the 2nd time and does not throw the message "Invalid Email" I am using AutoValidate feature to cancel validation if the parameters within the Regex match.But the problem is when I use AutoValidate or Set CauseValidation to false,the validation of TextBox is done the first time the form is loaded. Regex r = new Regex( (r.IsMatch(TxtPassword.Text)) Private void TxtPassword_Validated( object sender, EventArgs e) MessageBox.Show( " Invalid Email Format") Regex r = new Regex( (r.IsMatch(TxtEmail.Text)) MessageBox.Show( " Email Cannot be Left Blank") If (StrEmail = " " || StrEmail.IndexOf( " ") > 0 || StrEmail.IndexOf( ' "') > 0 || StrEmail = " " || StrEmail.IndexOf( " ") > 0) Private void TxtEmail_Validating( object sender, CancelEventArgs e)
