I have an ASP.NET web application that is using RegularExpressionValidator controls inside of a user control. The user control is placed inside of a panel with an ajax:modal popup. When I click the link, it will open the popup displaying the user control.
What is happening is when I click the link to open the popup, it is throwing a postback and activating the validators before the user has any opportunity to type anything into the boxes. I need to be able to click the link, open the popup, fill out the text boxes, and submit. The validators should only run when the submit button is clicked. Any ideas?
setting the validators parameters on the load in the code behind of the popupbox might fix your problem

I have some input fields, regular expression validators, and custom validators inside an ASP.NET ASCX control. The behavior is a bit odd in that it works the following way:
If a client side validator flags an error message and I tab away from the input field and click submit then the page posts as it should. However, if a client side validator has flagged an error and instead I correct the error and click submit button then the error is cleared but the page is not submitted until I click the submit button a second time.
My question is how do I change this behavior such that I only need to click the submit button once to both clear the error and postback the page? Also, is this "behavior" standard?
Update: This behavior occurs without using the user control. I believe it is specific behavior to the CompareValidator. Nope, same behavior occurs with custom validator. If I don't "tab away" and click the button then I must click it twice to get the postback to occur. The first click just clears the validators.
The issue is that the CustomValidator has display type as Dynamic and not Static. This post helped me to discover the answer
RequiredFieldValidator have to click twice
I will give credit for anyone who explains why it causes this behavior.

Think about using an IFrame to achieve this, from the sounds of what you are talking an IFrame would suffice and provided the needed functionality.
<iframe src="YOUR PAGE HERE"></iframe>
There's a lot more you can do with it, these are just the tags to get you going.
When using ModalPopupExtender inside a repeater, when the page loads, ALL of the popups appear without being called ( one for each item in the repeater) and then rapidly dissappear. With this, the popup works , but the problem is these popups being showed at the beginning. The popup is an OK/CANCEL popup, that triggers a postback when OK is clicked and does nothing when cancel is clicked. It is loaded on page load so that it exists when the user clicks on a linkbutton on the repeater. When the user clicks on the linkbutton, our intention was taht the popup appear directly without doing a postback, and this was achieved , just that small problem that random parade of popups at the beginning!thank you in advance!
I was not able to answer until now, sorry.
Turns out the HTML code and the CSS had conflicting codes and that made the popup appear!
I have an ajax control toolkit modal popup on my page and in that modal popup i have a gridview on which user select some item through checkbox on each row of gridview. Whenever user check or uncheck on checkbox my modal popup automatically hide. I have set autopost property of checkbox set to true becuase im perporfing some calculation on each checkchanged event. what may be the problem
Your page is posting back because of the autopostback="true" on the checkbox, thus hiding the modal popup.
Look up 'ASP.Net Page Lifecycle' for further understandinf. It is important to know how this works.
I'm sure you'd also like to know how to solve this.
You could:
Set AutoWireUp=false on the page, but then you'd have to wire all events on the page manually. Since you aren't familiar with the Page Lifecycle, I'm not sure how successful you'd be.
Use a javascript-only modal popup.
Perhaps an UpdatePanel can be used.
I have a master page with a search box and button at the top. This search functionality is taking over the "enter" key for all my web forms that use this master page. That is, if I have a login page that uses this master page and the user enters in their username/password and hits "enter", instead of logging in the user the system performs a search.
What's the best way to set up the default submit buttons. I could wrap everything in asp Panels and set the DefaultButton property, but that seems a bit tedious. Is there a better way?
use defaultbutton property of form or panel
<form defaultbutton=“button1” runat=“server”>
<asp:button id=“button1” text=“Same Page” runat=“server”/>
<asp:panel defaultbutton=“button2” runat=“server”>
<asp:textbox id=“foo” runat=“server”/>
<asp:button id=“button2” runat=“server”/>
</asp:panel>
</form>
As you have discovered default buttons can cause issues when there is more than one button on a page. I would take the Geeks suggestion but simplify it by removing the setfocus client script and extend it by adding the keydown event to both the search textbox and the login textboxes such that the enter key fires the correct button depending on if your user is using the search box or the log in box, or any other textbox you want to add the javascript to.
You can set focus on loading the page (in code behind if you like) to save the user some mouse work or tabbing if there is a sensible control for the user to start at, but otherwise the control the user is interacting with should determine the flow of the page and what the enter key does.
set focus on the text box ,
Page.RegisterStartupScript("SetFocus", "< script >document.getElementById('" + TextBox1.ClientID + "').focus();< /script >");
and then
In the keydown event for the last textbox you can do something like this:
If e.KeyCode = Keys.Enter Then
Me.Button1.Select()
End If
Rather than using javascript to manipulate the page you could put the search box and the submit button into an IFRAME on the master page. If the focus is in the iframe clicking will submit the search form, if the user is on your main form within the page they will submit the normal page.
The <iframe> src attribute points to a little self contained aspx page holding your text box and submit button which redirects to your search results form.
This is what we tried on our project which seemed to work. I changed the Search asp:Button to be an asp:LinkButton. I then added some CSS style to give it a background image to make it look like a button. LinkButtons are apparently not used by the page for determining which Button is the default action when pressing Enter. The sweet part was that LinkButton can still have click actions associated with them so I didn't have to change any of my code-behind stuff.
