Validation controls are good to use but plz guide is there a way that I can prevent validation controls to be validate on input and force them to validate on button press ?
e. g. In a textbox if a reqular expression validator is applied requirment is to make validator fire on button press not on entering text.
How can one fire a button click event when someone presses Enter in Textbox. I had a master page on which Search button & a Textbox for writing Search text is there. When one clicks on "Search" button, it works fine. But when one presses Enter, no search results are displayed.
View 3 RepliesI 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?

What is the best solution for adding Textbox controls dynamically to a page when a button is pressed?
The secnario is: "The page initially loads with 3-4 textboxes already displayed but the user needs another textbox added. They click add textbox and another textbox control appears."
I would hope to be able to do this within a updatepanel and use AJAX async postback.
- I'm using a RequiredFieldValidator to check whether the text box is empty. I only wanted this validation to run when I press one specific button.
- I dont want the validation to be done on every button control within a page. For example, i have 2 buttons, one is showing a list of data and another will be checking for an empty text boxes. So, when I click the show list button, I dont want the validation to be run, what I want is the validation to be run on the check empty text boxes button.
I have a web form where i have a key field "Account #" and ive put some live validations sort of function which validates the input text against values in database and instantly displays result if the account # is valid or invalid and ive put this on "onblur" event of the textbox.
The problem i am facing is that i have a "SAVE" button also and when user inputs account number the onblur fires and validates the input then user presses tab key fill other details and change his mind and go back to account # and type some invalid values and without pressing tab clicks on SAVE button with the mouse ..darn in this case it doesnt fire ONBLUR instead if fires SAVE event...how to overcome this problem and execute onblur first in any case.
I have to set enter key event to text box, it work fine in IE, but not in firefox.
Here my code:
function DoClickToButton() {
var keycode = (event.keyCode ? event.keyCode : (event.which ? event.which : event.charCode));
alert(keycode);
if (keycode == 13) {
document.getElementById('<%=Button1.ClientID %>').click(); return false;
}
else {
return true
};
}

Whatever server Control we take on aspx page while in coding phase, all those controls are converted to html controls through the asp.net engine and sent to the requesting web browser. That's fine.
Now, all the controls that are rendered on the browser are html controls. I am bit confused that how after pressing any button (Or any such control that post back pages) page is posted back to the asp.net engine. How such html controls comes to know where (address) they have to go?

View 1 RepliesI am developing and Asp.net website. Occsionally I will have to display A Java Script dialog box. The dialog box will have two buttons on it. One labeled "Proceed" and the other labeled "Cancel". Then I need two Java Script methods to respond to which button was pressed.

Anyway, I don't know how to invoke these methods when the dialog button are pressed.
