Vb prevent focus change textbox validating
You do not have to disable the Form’s Auto Validate property.However, I prefer to call it explicitly and handle all validation at once since you most likely will take action only if the entire control’s children pass validation. The most important thing to recognize here is how precise you can be with the validation error message in the error provider.As you can see its nothing dramatic or anything like that. Item("onclick") = "this.disabled=true;") then it would not do the postback. After the errors are fixed (entering in a firstname and lastname for example) then when i click it againit disables and since there is no validation errors, it does the sqldatasource1.insert and goes to the next page.I have 2 Required field textboxes (txt First Name, txt Last Name) and 1 Range Validator textbox (txt Demo Sent) that holds a date. in the On Click attribute for the Button and it will disable the button when clicked and still do the Post Back that was triggered, but it will still proceed to the next page. To String it will still do the proper postback along with disabling the button. But since i'm using the above one, it is doing the postback, just the button is being disabled no matter if the validation causes an Error or if it doesn't. Looking at your code and by playing around with code from other sites, I think I've managed to get the Button to Disable and continue the postback code once the page validation clocks off as true: I added the following code to my Page Load event:- It seems to work with no problems my side, but I've not given it a thorough grilling.
What I have no clue about doing (and yes I have searched high and low on these forums and all other places that Google could pull up for about 6 hours now sadly) is making the "Button1" or the Submit button disable when there is no validation errors. Item("onclick") = "this.disabled=true;" & Client Script. You can't directly disable that button as it will cause the postback to not happen as you probably already have figured out. Add("onclick","this.style.display='none';Element By Id('_disabled_submit').style.display='inline';); This should give you the same effect that you were looking Hi, you could consider using Client-Side validation APIs to verify page validation: OR you could disable your button within the form's onsubmit event. Ok so i continued to mess around with this and ended up trying something and this is what I came to. Hope I've been some help to you, and admittedly, I must thank you as your code helped steer me in the right direction.Let’s assume when we click our save button that we wish to validate the controls and display an icon if there is a problem.First, add the following code to the Form’s constructor after the Initialize Component method: This is a handy trick to prevent implicit validation of our controls when they lose focus.Let's create a text box by dragging a Text Box control from the Toolbox and dropping it on the form. Text = "tutorialspont.com" End Sub Private Sub btn Message_Click(sender As Object, e As Event Args) _ Handles btn Message. The following are some of the commonly used properties of the Text Box control: Public Class Form1 Private Sub Form1_Load(sender As Object, e As Event Args) _ Handles My Base.
