1. Is it always required to use javascript to do client side validation.
2. If we dont want to use the script then can I write the code in c# for validating a control like text box using the events.
3. If I write the code in c#, does it always requires a postback?
how can I implement validations for controls in c#. I am not familiar with javascript, so is it good to write the validations in c#

View 1 RepliesI want to implement validations in setter of properties.

A thought was to use return but it is not allowed.
Throwing error looks not good as generally we avoid thorwing custom errors.

I want to Add, edit, delete and update the records using gridview with validations.
I am not using any default datasources like sqldatasource or accessdatasource.
Want to do it in code behind.
Validations should be used as if some one try to update the value as blank or do not enter characters/numbers like that.
I have a form that uses ASP.NET validations. I am using some inline C# in the aspx to show/hide certain controls depending on a user's role. I would use the Visible property, but there are so many of them, I just decided to do inline C# to show and hide (I know, not best practice, but bear with me for a second). I am having an issue where Page.IsValid is always set to False when I submit my form (when certain fields are being hidden). Will the validations still fire off even if the controls are not even rendered on the pag? Also, if this is not the case, is there an effective way of breaking down Page.IsValid to find out what is setting it to False?
View 2 RepliesTo me this should be much easier, but I can't seem to retain the values that are put in the Insert template upon a validation failure or when the sql fails. This will prevent the user from having to retype everything agin in the event of a failure.
As you can see I am using the Sub Insert_Click and not using an insert through the wizard. so the fields are unbound textboxes on the form. There are 2 dropdowns that provide choices for the other fields.
I pasted in the code using the text only option becuase the format was getting messed up. I probably need more background on why the fields are blanking out.
