I'm trying to write code that responds to a button click event that will make an asp.net drop down box reveal its list. Hence, this will eliminate the need of the user to actually click on the drop down list. Can someone write out the code for this in c#.

[code]....
Right now my ASP page has a text box and a submit button, what I am trying to do is once the user hits the submit button load a drop down list.
The drop down list should not be visible before the submit button is pressed
How would I create a list then on click add data to the list which is then stored into a session variable, then on another page retrieve the variable and output them? Currently I have:
Page Load:
List <myClass> listName=new List<myClass>
OnClick:
listName.add(3);
listName.add(4);
Session["IDs"]=listName;
Second Page
I need to get the whole list and add output the list so I can output (hopefully) the '3' and '4'.
i have a web form in which i ve a button which will open a sliding pop up box(jquery) on click of it. In the same page i ve also a linkbutton for downloading files. Now the problem is first time wen i click that button it does nothing. (will not open popup box). Once i click on download button and then if i click that button it will open popup box along with download dialog box. Why is it happening so... is it because am using same event click for both these.
but download option is implemented in gridview_rowcommand()..
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:

On my Search page, I have a search textbox, four drop-down lists and a "Search" button. If I use only the drop-down lists and click the "Search" button, results are immediately returned. However, if I enter text into the textbox and click the "Search" button, nothing happens until I click the "Search" button a SECOND time.The processes that occur for the latter scenario are as follows:Text entered into textbox, and Search button clicked:On FIRST click attempt:
1. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Search.aspx is called
2. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Main.Master.vb is called
3. Process stops! No results
On SECOND click attempt:
1. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Search.aspx is called
2. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Main.Master.vb is called
3. Protected Sub SearchSubmit(ByVal sender As Object, ByVal e As EventArgs) Handles btSearch.Click for Search.aspx is called
4. Search continues and completes.
So, why will the 3rd step not kick in until clicking Search for a second time

I find a special circumstances as follows:
My web form contains a postback button. The button will postback and call a server-side method. The method will process something that may spend about 20 seconds. However, user may try to click the button several times within the waiting period. The sequential clicking may cause the first running method incomplete and stop, since the second click postback will dominate the method and start again. How can I solve it?
PS: It can not use client side script to disable the button, because it requires to use some server-side validation within the method.
I have two listboxs, one contains the author list and another contains the author for the selected book.And I have button two move author from first listbox to second listbox. All are working but the problem is:If the author is already exist in the second listbox, do not move from first listbox.So what kind of code can I write into move button so that it checks the selected value in the first listbox with the values in the second listbox, if exists; display the message "Already exists; try another one"

i have a listview (inside an update panel) in a user control with two columns in each row. the list view is bound to a datatable via a stored procedure. i use the control on a web page and on the click of a button (which is not inside the listview, but in the user control) i want to add a new row at the end of the listview which should add a row with two empty text boxes (one for each column) at the end of the listview.
i am currently able to achieve that, but only on clicking the Add button TWICE.

I got a function to load a grid view and works fine. Then, I got a button, when click, I wanted to add a new row into the grid, what I did is I add a new to to the dataset and rebind the dataset to the grid view.
The problem I faced is that is it able to add a new row, but it only shows ONE column only, which is the most left column.

im now created a function where i can import excel file to be displayed in gridview and then insert the data from gridview into database.
It is running smoothly until i copied the page into another file. Suddenly, when i try to display the gridview, it does not appear.
I've try copied everything exactly the same like the original one, but still failed.
Does anyone have experience like this before?

Moreover, before Saving I also want to check if that User is not already registered by checking Email ID.

I require HTML button since there are some HTML fields whose value gets blank as soon as page is postback(which happens if I use .net button Control).

What I am trying to grab in particualr is the PayRoll Label. I've named sequentially as "lblPayRoll" + the counter. Which from what I think I should be able to do is get the total count of my array and from then loop through the controls and grab the label data.
Problem is that I can get the data, but it disappears after I click the button to grab it. I think I am saving everything to the viewstate, but they just disappear.
