[code]...
The first time the page is requested, it displays the gridview with the data. But when I click on the button, the gridview disappears (and only the button shows up). When I comment out the code: int x = GridView1.Rows.Count; in the Page_Init(), the gridview does NOT disappear. Why is that one line of code causing it to disappear?
In our site we are having a peculiar problem with SSL green bar. When we load the page SSL Green bar is showing up in the URL as usual but it diseappears after one second. I checked the view source and all the images are pointing to https only. I could't understand exactly what is causing the disappearing of Green SSL bar from the URL. Is there any thing that I need to check?
I am developing a C# VS2008/SQL Server 2005 Express website application. I'm a newbie to ASP.NET. I am using one of the database files in my App_Data folder. Also, I am trying to implement Security into this solution.
Everything works fine until I click on the Submit button. I traced through the code but didn't see why my Hashtable was changing to null.
Possible causes I've thought of:
currently some of my methods are protected, some are privateI have no Page_Load method defined in the DataMatch.aspx.cs file. Instead I have a Page_Init method. I have included most of this DataMatch.aspx.cs file--hopefully this will give you enough info.
ddl_ht is the hash table that is getting set to null after it enters the btnSubmit_Click method.
I am also including my DataMatch.aspx code now also.
DataMatch.aspx.cs file: public partial class DataMatch : System.Web.UI.Page { string targettable = ""; DropDownList ddl = new DropDownList();
... nothing is displayed. However, outside of the <% %> tags (ie in the HTML) £ displays correctly.
I have no trouble displaying the usual alphanumerics, it's just the £ sign that is proving problematic. The underlying file is in Windows 1252 encoding, and I need to serve it as such. If I save the file as UTF-8, I get mojibake instead of a £.
what I can do to make this work, or any settings that might be preventing it from working (other than saving the file in a different format)?
I use shared hosting. I have set my page to be cached indefinitely. The page gets cached after the first request. However on the next day when I visit my site it is no longer in the cache and has to be regenerated.
What is happening? Is the hosting removing my pages from the cache? Or something else?
I have a GridView (insde a UpdatePanel with a Timer control) which is refreshed every 3 seconds and one of its fields (a TextBox) is "linked" to a HoverMenuExtender. It works great to display the Multline Textbox results but when the next refresh timer intervalcomes the TextBox control is re-populated with the new data and the user does not have the time to read its content.I am not sure if there is a way to maintain the content after each refresh (as long as I don't move the mouse of course).ere is part of my code:
I have a tabcontainer with three panels. Initially the second tab is not enabled. I have a button in the first panel which when clicked, enables the second tab and changes the focus to it via the code-behind (requires a post back but that is desirable, since I shall put business logic there).
Works perfectly well.. but if I repeatedly keep clicking the next and the disable buttons.. once in a while the entire page disappears.. i.e I get a blank browser screen (IE6 and Chrome) and in FF the second tab doesn't become disabled at all.

I have a page that has a dropdown. When I select a value, it does a post and depending on the value, it get a webuser control and inserts it into a placeholder. The code is below. On the webuser control, there is a fileupload control with a button that does a post to upload the file. When I post, the web user control disappears?
I am designing an user control in ASCX similar to which is shown in the link below [URL] I am using textbox with Div around and image for arrow and a listbox group control for multiselect option and wrote a javascripts to show and hide the listbox when onclick of image arrow. I could achieve everything except when I click on outside the list is not disappearing
I have an odd error with an ASP.NET web page (ASP.NET 2.0, C#). For several users at one customer location, on one part of one page, HTML content and attributes are being stripped out. So, something that should look like this:
<p class="adminmainlink"> <a href="ad_resourcewizard.aspx">Add or edit resources</a> <script type="text/javascript">
I have a small tabcontainer at the footer of my page with a gridview in several tabs - this works fine. Customer has asked for a re-design and for the tabcontainer to cover the entire page. When I increase the size of the tabcontainer (say to 550px) the gridviews disappear!
Noticed a few things;
- If i move the gridview before or after the tab container it is displayed
- There is definatly data in the gridview
- Controls on another tab work fine (these are the ones that were previously covering the rest of the page)
what might cause the back button/history in Internet Explorer to become greyed out when navigation between web forms occurs?
Example - I have a hyperlink on my main webform that when clicked directs the user to a second web form. This web form has a variety of databinding occuring. When the page has finished loading/binding, the back button goes from blue to grey. It appears that the referring page is removed from the history as well.
I put loginView control inside ModalPopupExtender, the problem is: when I try to login with wrong user/password and press the login button, this button cause a postback and then the page reloads and ModalPopup dissapears, only when I press the button wich cause ModalPopup to show itself, I see the loginview control with the message "username or password is wrong"
What can I do to prevent ModalPopup from disappearing after wrong login?
- I've created a Survey with multiple sections in it
- The answer types are variable and, thus, the controls are created dynamically
- I have a Repeater where each RepeaterItem corresponds to a Category. (I have 5 categories in my current test, so I have 5 DataItems in the Repeater) Each RepeaterItem contains another Repeater which will hold the Question / Answer values
- After I data bind the Category Repeater, I loop through each RepeaterItem, find the Repeater contained in each RepeaterItem, and DataBind() this second Repeater to a list of Questions
- After DataBinding the Repeater containing the Questions, I sent that Repeater object to another routine, which is where the Answer controls are dynamically created and added to a Panel inside each of this Repeater's RepeaterItems.
I am able to navigate back-and-forth among Categories, save / delete answers, and fill in answers for Surveys that were left incomplete when a user logs back in.
One of the the potential control types for an answer is a ComboBoxList.
Each Question has an option for answers that require a ComboBoxList called "MaxAnswers." When this value > 0, I inject a little javascript that prevents the user from selecting more boxes than the "MaxAnswers" value. This is done during the last step described above like so:
[Code]....
This appears to always be added regardless of how many questions I answer or don't answer or how many times or directions I navigate around inside the survey. (I can push "Back" and "Previous" buttons as well as jump directly to any individual category by clicking a LinkButton)
Another option for Questions requiring a CheckBoxList is to specify if the selection of a specific ListItem within the CheckBoxList should display a TextBox. (e.g. a selection of "Other" will display a TextBox for the user to write-in an answer) I want to prevent a post-back just to show/hide a TextBox, so I inject an onclick event attached to the specific ListItem to accomplish this. The following code appears as the very next routine following the code pasted above:
[Code]....
This also works the first time the page is loaded but not after any PostBacks...
The lblMessage.Text lines are written to the page after ever PostBack, the MaxAnswers routine correctly adds the onclick event to the necessary CheckBoxList controls, but the "fncShowFTB" event is not added. Viewing the HTML with Firebug does show the onclick the first time the page is loaded, but it's missing after every subsequent postback.
Can anyone see what I am doing wrong that causes me to lose this event?
I am having an issue where i have fields on a form that contains an update panel that i want to do Jquery validation on. The issue is when i click the OK button, the validation error message appears then goes away. the code is below:
i have created aspx pages with left navigation menu control... when ever mouse over the menu control some elements disappearing... that disappeared elements having position:relative CSS this problem having IE6.0 and IE7.0only
Have a Order entry application where create a Cookie to store OrderID when 1st item is purchased. Then go through a series of 3 pages to accept shipping info, etc. When we get to the Payment Method page a button allow user to pay via PayPal. If clicked a call is made to Paypal to log user in. PayPal then redirect back to application page called "PayPalConfirm". When we get back to the confirm page the OrderID cookie is missing!
Here is how I create cookie and set expiration to 1 day: Response.Cookies("OrderID").value = "ABCD" Response.Cookies("OrderID").Expires = DateTime.Now.AddDays(1)
Again, the cookie exist through several pages but when return from PayPal it is gone.
I am new to jQuery. i place the return false to stop postback, that postback is stopped, but error messages are appearing. How can disappear the message by click cancel button. I used e.preventDefault() also it not working. here my code:
I have a site that show infomation that are contained in div blocks. The info is taken from a database so the user can change the info or delete it. When the user deletes a div block i want to use jQuery to animate that its disappearing and also that its deleted from the database. How can i do this without doing a postback, i dont want the site to reload, i just want the Div block to disappear visually and be gone from the database at the same time. Would i use Ajax update panel to achieve this ?

I am using the following code to load user control on to ASPX Page, which under a Master Page:
[Code]....
The user control name is passed as a parameter on the URL.
Inside the user, there is a LinkButton. The link button has a simple server side code for OnClick event.
Everything is working fine on the production machine, but, on the Development machine, I can see incorrect behaviour. I have started making some development changes on the Development Machine since several months back, and it will be very difficult to find out what caused the problem.
When I click the LinkButton inside the user control, the user control is removed from the parent page, and the OnClick event of the LinkButton is not firing.
I did debug, and found out that after I click on the LinkButton inside the user control, then the Page Load events for the master page and the ASPX page are working fine, and the IsPostBack is set to true, but the OnClick event of the LinkButton is not firing.
I created three web pages: Page1, Page2, Page3. In Page1, two variables(Var1, Var2) were stored by subkeys(Key1, Key2) in a single cookie. After storing, Page1 was redirected to Page2 by Server.Transfer() as the following code:
If Cookies("MyCookie") isn't rewritten by other code, it should return Var1 ~ Var5 respectively to execute Request.Cookies("MyCookie")("Key1") ~ Request.Cookies("MyCookie")("Key5") in Page3. However... Strange things happened, Var1 and Var2 were not returned, but empty string are returned instead.
As noted above everything appears fine until update button is clicked. The page refresh is blank - the formview displays no data. What's strange is that when I go back to that page the formview will not display data. The data is in the database, updated as expected. I tried rebinding on postback, nothing. The empty template is displayed.
