Firing both Client side event and server side event for server side button
I would like to make a server side validation after calling a js function that makes the client-side validation.
I do not understand couple of things:
1. Do i need a server side button or a simple HTML submit button in order to call both of the tests?
2. How do i call a server side function which is written in csharp after i finish my JS validation (the submit button is calling the JS function for validation first.)- is it possible to call it directly from a js function?
3. I know that my toolbox on asp.net contains validation controls who probably are b...Validation Controls in .NET ( Client side or server side?)
i have a very basic question. We have all these validation controls in asp.net ( required field, range validator and others)..my question is the required field validator is a server side control. So does that mean that it does a post back?..is it client side or server side control
The only controls that post back are buttons and other inputs where you set AutoPostback="True", such as a dropdownlist or a textbox. Another way of posting back is using an UpdatePanel and placing a trigger in it for a specified control and/or event.
All controls are considered clien...Can we check validation both on client side & server side?

i see a web form that consists of three controls :textbox,requiredfieldvalidator that weired to the textbox and a button
within the click event of the button there is the following:
if page.isvalid then
response.redirect("Page is valid")
response.redirect("Page is not valid")
according to my understandings:
when the user does not fill anything in the textbox and then clicks the button the the page will not be submitted (i.e no request to the page will be happened or no postback will be happened) then no server event will be happened so it is sure when the us...Server Side Validation vs Client Side Validation

I see an inaccurate validation behavior on my asp.net (2.0) form. The EnableClientScript property of my validation control is set to True by default, so it performs the validation on clientside. But as soon as this occurs, it also performs the server-side validation, so the page refreshes. When the validation error occurs on clientside, it should not do the validation on serverside (I'm not calling Page.Validate() or doing Page.IsValid). In my past experience, asp.net handled this automatically, but I guess it's not always the ca...client side and server side validation
I have multiple usercontrols each displayed by pressing a button and then change the apperance to a new user control and so on. I have to check that almost every field in this user controls have a value entered, and then indicate (e.g. with a red star) those textboxes that does'nt have a value entered. How should I do this in the best way, client side or server side with some validator? I have in mind that when using a server side validator, it may dissapear when making a postback. But I'm not sure, and I assume there is a way to come around this problem?What do you all say? Client side or s...Validations client side or server side ???
