DropdownList Reset In Updatepanel On Submit Button?
Oct 7, 2010
I have a dropdown list which is in updatepanel. I have to fill that dropdown on a client event through javascript which calls __dopostback of the updatepanel and calls its load event.
Problem is that when i submit the form updatepanel_Load event also execute again and it again reset the DropDownLIst which causes the loss of selectedValue in Dropdown.
On page Load this dropdown is Empty .... no funtion to fill it.Now the problem is when ever I Fill the Dropdown throught Load of UPatepanel, that UPdatepanel Load event also execute when I submit my page. Actually the solution of javascript is due to a table and on Selection of the table row item it Fills the DropDownList from __dopostback of my updatepanel.
I have button which opens a popup window and that popup window contains a table, when client select some item from that table and close that popup window then I fill my dropdown (in parent or opener page through Ajax, Updatepanel's Load) as further selction option. so dropdown databind is dependent on that tables input.
I have a web form with some labels, textboxes, buttons and a gridview. The gridview has AllowPaging ="true". Girdview displays record numbers (hyperlinked), When I click on a record number in the grid view it populates textbox1. Then I hit the 'Search button to auto populate the form the that record data from the database.
My problem is when I am on say 5th page on my grid view and click a record number to go in textbox1, and then click on the search button to auto populate the form, the gridview goes back to page 1.
How do I make the search button not reset/refresh the gridview?
I am using upload feature in my asp website. So i am using file input type. But this control add a default upload button browse and a textbox where path is shown after selecting file in Internet explorer. I don't want to show browse button etc. So what i did is add a button "Attach a File" and i have written script 'triggerFileUpload' function where i make it to click on upload control.
So now when i click on "Attach a File" button browse for file windows appears and can select file to upload. But when i click on submit button the file upload control becomes reset and file is not uploaded. Error is that on clicking to submit button the file control becomes null. It happens only in internet explorer.
Below is code which can show the problem i am facing in IE.Same problem comes if i use asp:FileUpload control also. (my plan is to hide the file control and show only attach file button to user).
Have a dropdown list with autopostback set to 'yes' have another dropdown list box that will be populated based on the selection of the first dropdown. It works fine until I put a submit botton on the form. When I do it appears to not do the auto postback until the submit button is pushed. Can you have a submit button on a form that has a dropdown with autopostback active.
I have three drop down lists that are all databound to a gridview. When the user selects 1. a school, 2. a house number, and 3. a street from seperate drop down lists, bus stops for that address are displayed in a gridview. Everything works fine. After the user selects a valid school/house number/street combination the gridview automatically displays. I would like to add a "Submit" button and not have the gridview display until this button is clicked.

I've read several questions explaining how to handle file uploads in asp.net mvc. I am trying to submit both the file as well as form fields describing it. That might be the issue. I'll go write to the code:
View code:
<% using (Html.BeginForm("CreateFile", "Video", FormMethod.Post, new { enctype = "multipart/form-data" }))
I've seen several examples, but haven't come across one that is trying to submit both a file and other form data. Some other things of note is other examples seem to not put a HttpVerb attribute on the action method at all and have an empty parameter string. The files I'm looking to accept will be video files of various types but they can be anywhere from 100-300 mb. The files I've attempted to use (locally) have been rather small comparatively (50 or so mb).I know it's been asked but I feel like my issue here is different somehow. When I submit the page I see:
The connection was reset
The connection to the server was reset while the page was loading.
I'm currently having an issue where an updatepanel does an async postback and loses the tab order when the partial postback occurs. When you run through the tabs the tab order works correctly, but then you press a button and the partial postback occures the tabindex is reset. Is there any non-javascript solution to this. If not, what would the javascript solution be?

I have a cascading dropdown list on my page. The first dropdown contains a list of events. The second dropdown contains a list of attendees. When an event is selected, an AJAX call is made to get the list of attendees for that event, and populate the second dropdown.
My problem is that for the attendees dropdown, I want the user to be redirected to a URL on the SelectedIndexChanged event, with the selected value in the query string. But on the SelectedIndexChanged event, all the items in the second dropdown are reset. Here's my code:

I have 3 tabs with 3 seperate gridview and radios buttons in them.

I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
I am working on an ASP.NET 2.0 website. The issue that I'm having is that it queries a database to get the info it displays on screen, but the database occasionally gets to where it has too many open connections. This causes the website to reject the attempt to log-in for anyone, after that database error.This is caused because many users will log-in, do what they need to do, but then leave the website running while they do other things without logging out. It will time out on them, but the connection still seems to be open. We then have to contact the person in charge of the server it's running on and have him reset it for us.I have looked and all connections made to the database seem to be closed after the request and query is made. So, what I want to do is to add a button that when clicked will reset the website, instead of having to call the guy in charge of the server every time. Then we can reset it whenever we need to. So, how do I reset an ASP.NET 2.0 website with a button on one of the pages inside the site?
