I have a validator with a ValidatorCalloutExtender. The validated TextBox is set to empty string after postback and this unfortunately causes the callout to popup. There must be a way to restore the validator to its initial state but I cannot figure out after trying quite a few things including setting IsValid to true.
View 10 RepliesI have compare validators that I build on the fly in code behind that validate textboxes that are also built up in the code behind:
[Code]....
These work fine until a postback occurs. After a postback they still validate the form (i.e. they don't let you postback) but the error message won't display.
Required field validator error message is disappeared, after post back event. how to maintain the Required field validator error message on post back also?
<asp:RequiredFieldValidator runat="server" ID="reqProductName" Display="Dynamic" ControlToValidate="txtProductName"
ErrorMessage="Enter Product Name" ValidationGroup="registration" ></asp:RequiredFieldValidator>
I'm learning asp.net page life cycle. I find an article on MSDN [URL] It says that If the request is a postback, control event handlers are called. After that, the Validate method of all validator controls is called, which sets the IsValid property of individual validator controls and of the page. And the picture in the article also says validate fires after event handling. If this is true how can I get status of validator when I handling the event?
View 3 RepliesI have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?

When it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?
I have a validator callout extender that works, it shows the callout box. But, it does a postback. It didn't do a post back the first time I clicked the button but it did for subsequent times. I read on the AJAX site that a custom validator must be used with this for it to work. I'm currently using this with a required field and regular expression validator. It works, the callout appears, but it doesn't work every time with out the post back.I posted this to see if there is a way to get this to work with a required field and regular expression validator, with out using a custom validator. I'm using the newest release of the toolkit, so I thought the documentation may be old, since the callout is appearing.

I've integrated CKEditor to my ASP.NET app which is working fine. Here's how I'm using it -- I've noticed that a lot of people had issues with this:
[Code]....
Nothing fancy but it works. My issue is with integrating RequiredFieldValidator with this. When add the the validator, I have to hit the submit button twice. The first time around, I get the validator message telling me that tbEditor is a required field even though I already have filled out that field i.e. tbEditor.If I hit the submit button again, everything works fine but clearly this is annoying. Any idea how I fix this?

View 2 RepliesI have a table that displays data by year. The year headings and data selections are dynamically generated, so that the code does not need to be changed every year. Each cell has 2 validators on it, and the ErrorMessages for each validator needs to say the item and the year. On top of that, the validators are in FormView templates. I know how to set the ErrorMessage text in code behind, but I am wondering if there is a way to do it more efficiently. Right now for each cell I have to code:
string Year1_Text = ...code to set the year...
RequiredFieldValidator Year1_Item1 = (RequiredFieldValidator) FormView1.Findcontrol("Year1_Item1RequiredFieldValidator");
Year1_Item1.ErrorMessage = Year1_Text + " Data Item Is Required";
CompareValidator Year1_Item1 = (CompareValidator) FormView1.Findcontrol("Year1_Item1CompareValidator");
Year1_Item1.ErrorMessage = Year1_Text + " Data Item Must Be Numeric";
With 5 years and 10 data items, that will be a LOT of code. Is there an easier way?

I have more than two text boxes in my web form.Now I want to validate either of the text boxes value is empty then only user should get error message i.e enter either text values.
For ex: There are two text boxes Phone no and Name. If user clicks on submit button without entering in either of text boxes then only user will get error message i.e enter either phone no. or your name .I can use the javacript in order to solve this case but I want to know is there any control in asp.net to solve this purpose?
I have a a web form with multiple formviews and one field is a mandatory field. Each formview has its own submit button. User cannot submit the data in any of the formviews until that one mandatory text field is entered.
But I also have another section in the webform, which has a calculation code in it. It takes in input from two text boxes, does some calculations and displays the result in another text box. Because of the validator control, I am not able to run the calculation code without the mandatory field filled in. I would like to run the calculation code irrespective of the mandatory field.
How do I do this? I need that submit button (in calculation section) to disregard the validator and display the result.
I am adding validator controls to a page on runtime. When I do this it seems to work except for one thing: the page doesn't get validated (the Validate() method is not invoked) - neither on the client nor on the server. However when I can Validate() myself, the validators do their work and generate the required errors. So it looks like the simple fact of adding a validator programmatically causes the page validation to not take place. My page does have validators in the aspx file - they work fine when I don't add any programatically, but as soon as I do add one programatically, the Validate() method is not invoked.
The way I add the validators is by creating an instance, giving values to all relevant properties, and then adding to the page control collection. I tried this in the PageLoad, and prior page-cycle events. The same result occured. I also tried with or without having a ValidationGroup, and with or without having a ValidationSummary control on the page. The same result occured.
