Using javascript or jquery, how can I make a Required Field Validator control (of ASP.NET) visible. If we check the viewsource of the Required Field valiator, we can see that the visibility is false initially. $("#spanReqFieldValidator").show() / fadeIn() wont work.
From googling, I understand that jQuery has some issues with visibility attribute.
How to use single requiredfield validator for two or three textboxes in asp.net ?
View 1 RepliesI'm adding RequiredField validators to a group of RadioButtonList controls, and something strange is happening when the page loads. The page renders just fine with no validators tripped, but as soon as I click on one of the radio buttons, the validator for that RadioButtonList fires and shows me the error message. I initially thought that maybe the various validators were cross-linked, so I tried clicking on a radio button in every list, but they all react the same. Here's the code that generates the whole thing:

I got a problem when using required field validator in datalist ,We have 4 polls. In that user must answer two polls which are required.I have added all the four polls in my datalist ,it is displaying fine and while clicking submit button the required field validator is working and giving the error message. Once we answered the required polls and clicking submit button again, all other polls which are not required showing as required one.My poll answer getting submitted thats not a problem ,I want to avoid displaying the error message for non-required polls.Here is my design and code:
<div id="pollQuestion_div" Class="read-messages-poll" runat="server" >
<asp:DataList ID="PollDataList" runat="server" onitemdatabound="PollDataList_ItemDataBound">
<ItemTemplate>
<asp:HiddenField ID="PollIDReqHiddenField" Value='<%# Eval("PollID") %>' runat="server" Visible="false" />

<asp:ListItem Text = "Kidneys Donor" Value = "Kidneys Donor"></asp:ListItem>
<asp:ListItem Text = "Lungs Donor" Value = "Lungs Donor" >Eye Donor</asp:ListItem>

I am trying to make a button visible for users that are either in admin or manager role. I can't seem to figure it out,
Code:

How do I capture other events in an asp.net textbox on a webpage in more of a way in which a windows app does? For example, if I want to handle when someone just presses a key (keydown) on a textbox in a webpage?
The functionality that we want to create breaks down like this:
We want to create a "smart" search box at the top of our page. When the user starts typing, a little panel or some element should become visible and it will have some check boxes on it. They can search for one or many different types of searches: First Name, Last Name, Business Name, ZIP, Customer Number, and Contact Info. As they begin typing their search, we need it to execute some code that attempts to figure out exactly what they are searching. So if it can tell they are typing in alphabetic characters and not numbers, then we know to NOT check the Customer Number box, but we will want to check the First Name, Last Name, and Business Name boxes. If they start typing a number, we know that we can check the Customer Number box and leave the First Name and Last Name, etc boxes unchecked. If they type a number that is 5 digits, then we know to check the ZIP and Customer Numbers both. Any other length number characters and the ZIP will be unchecked. And any other rules like these that we might want to implement in the future. The idea here is we will almost always be able to tell what someone is searching, but the user can always check any box that they want to search for if they so choose. For example, if a business is named "123 Plumbing Company" and they just want to search the Business Name field for a number, they can over ride it and do that. Otherwise, they just can blindly type their search and hit enter and the program will usually know what kind of search they are trying to do.
I come from a strong windows app development background and have just recently tried to do some web development professionally. A quick few sentences on what philosophy I am missing out on as far as a more robust and "Windows App-like" webpage would be appreciated if anyone wants to coach me on that area and point me in the right direction!
Also, in my example we are using master pages. So if you can imagine a typical master page that has a logo top left and a search box and button top right, then you can picture what we have. Its simple looking. But with the content page being a separate aspx page, we are having trouble referencing it after a search is performed anyway. So what I mean by all this is The masterpage.master has a search textbox. They type something, hit enter. We then want a gridview that is on our default.aspx page to update with the results of the event that was fired from the masterpage.master.
My windows app background tells me to just point to it like I would from two different forms. Like if I had a form1 with a search box on it and I wanted it to show up the results on form2, I would just say Form2.Show: Form2.GridView = whatever.
Of course, with my confusion of what the scope of these asp.net pages is, I am having a difficult time just visualizing everything and how they are inter-related.
So I guess to recap here:
1) How do I tap into more events with textboxes or any other asp.net control. Is the answer AJAX? If so, can you elaborate just a little bit?
2) How would I use the keypress or keydown type of event to make a panel or some kind of content holder to become visible when the textbox gets focus from the cursor and go back to being invisible if it loses focus.
3) What about the scope in which asp.net pages behave?
i have a panel(visible false) in a page and a user control. i have a button in a user control when i click that user control button then i need to make the panel visible in the page... (panel which is not in the user control)...
View 3 RepliesI use DropDownExtenders everywhere in my project, but it bothers me that it's not visible all the time. It looks like an usual TextBox :-(
<script
type="text/javascript">
I have a Panel with property, Visible set to False
<asp:Panel ID="pnlUpload" runat="server" Visible="False" />
and i try to make it visible using javascript as code below
document.getElementById('<%= Panel1.ClientID %>').style.visibility = 'visible';
I'd like to be able to have the .NET AJAX CalendarExtender show on Load without having to click in a TextBox. If I can simulate a TextBox being clicked so the CalendarExtender will show I'll take that too.
View 1 RepliesI have a project that uses a CSSHandler with images and css style sheets in the project root directory in their own folders (img, styles, App_themes). I also have a sub application that comes with a MasterPage. The sub application is located in a separate folder in the root directory with all its images, css, and pages. Functionally the sub application works, but the formatting is lost. The images and colors are not displayed. How can I make the sub application's css visible to its pages? It has probably something to do with the way the CSS handler delivers themes and css style sheets?

View 9 RepliesI've successfully used the xmlhttp object to redirect (xmlHttp.open) user to another page but I have the following issue ..I have a classic ASP application that has some very antiquated "admininstration" functionality built in that loops through a SQL table with NT Accounts and allows the link to only be visible to users with NT account in the table. We have since moved on to manage permission to our .net apps using an object that looks for your NT account in an Active Directory Group. So, I would like to use the .net object to return True if NT account is a member of the group and then display the link (which is in the classic ASP page) if the .net object returned true.I don't know if that can be done .. I just know I'm able to return the TRUE value using the xmlHTTP ajax object but I only want to set visibility of a link rather than xmlHttp.open to redirect to another page.
