I have page with several textboxes, dropdowns, and check boxes on it. When I click my update button and the update happens, at that point all of the textboxes on the page are locked, I cannot click into any of them. The dropdowns and check boxes still work.
I do have an update panel on the page:
[Code]....
I'm creating multiple textboxes dynamically bases on different criterias, after that every time any control is posting back to the server,
i need to regenerate all the dynamic fields.
What should i do to make the controls stay once added to the form even if a post back occurs.
I'm trying to make a form that could have one or multiple textboxes. I have a textbox and a button to add additional textboxes.
I have no problem adding a second textbox inside a panel but I want to be able to keep adding more textboxes every time the link button is clicked and later reference those boxes to be saved. I would also like to maintain the value of the textboxes there. They are not saved to the database until all the necesary texboxes have been added.
I added the textbox using:
private void button1_Click(Object sender, System.EventArgs e)
{
TextBox textbox1 = new TextBox();
panel.controls.add(textbox1);
}
that works fine, but when i click the button again it doesn't add an additional textbox which is what i need.
This is fine with a single textbox, but I want show different value from database into different textboxes.
How can I do that?
I have an asp.net dropDownList listing hours and minutes of the day. I want the time chosen to be shown in a texbox. Can this be done without making a postback?
View 4 RepliesI have "n" <tables></tables> on my page and each <table> has One(1) <asp:CheckBox.. Enable ='true"/> and "x" <asp:TextBox Enabled="false"..>. Each Table looks as follows
[Code]....
When I click checkbox, it calls javascript function and enables textboxes (I have added onclick attribute to checkbox). Page also has <asp:Button ...Text="Submit"/> whcih actually grabs the data from the textboxes on the page and send it to the databse. Here is the Onclick event of the <asp"button../>
[Code]....
If the exception is thrown , textBoxes are not reset but on postback textboxes appear as disabled (values are not reset)
So here is what happening on postback when exception is thrown
1) Values are not reset (that is what want)
2) Texboxes appear as Disabled (that is what I don't want on exception, REMEMBER I enable textBoxes using client side script)
How can I keep the textboxes enabled = "true"
I used the code for gridview within a gridview using jquery functions for expanding and collapsing as shown in article : [URL] .... It works well, but I have textbox in childgrid and it behaves wrongly when i submit childgrid data for saving, it shows character comma (,) before data entered in textboxes.
I commented all coding for submit button outside both grids, then also on clicking of submit button, there comes comma automatically in textboxes in child grid..

<script type="text/javascript">
$("[src*=plus]").live("click", function () {
$(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>")
$(this).attr("src", "images/minus.png");
});
$("[src*=minus]").live("click", function () {
$(this).attr("src", "images/plus.png");

I have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx
[Code]....
[Code]....
Repeater.aspx.cs
[Code]....
Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.

View 13 Repliesi want is to copy huge data from many tables to a master table in my database.
the copying process should executed once at the time from asp.net.
so if a user "A" start copying process, user "B" will not have the permission to copy untill the old process (started from user "A") complete.
what i am thinking to do is if its possible to lock "Copying Function" from using more than once at the time.

I have two roles admin and member. In my application, admin can manipulate most of the member data. I know that in forms authentication a user can be unlocked like,
MembershipUser user = Membership.GetUser(clickeduserName);
user.UnlockUser();
Membership.UpdateUser(user);
My questions are,
How to lock a user in forms authentication? Why is MembershipUser.IsLockedOut Property set as ReadOnly? Is it not the right way to LockOut people as an administrator?
I need to know how many ways I can lock a file? Suppose a process has opened a file and reading or writing it, by this time another process try to open it and read or write, how many ways I can impose lock level on that particual file?

View 3 RepliesI have a FormViewwith several bound textboxes whose values (text) are generated in code. The textboxes are bound to the data with Bind("<FieldName>"). Because there values are generated in code, I'd rather not let my users change their values. I have tried making them read only. However the values of the text boxes did not update when the form was updated. I tried disabling the textboxes but that grayed them out. I tried replacing the textBoxes with labels while keeping Bind("<FieldName>") but that didn't update either.
(1) Am I doing this right? (2) Is there any way to lock the value of a text box without graying the textbox?
Does anyone know why the lock that is to show when on an https site would show, but then vanish once the page is done loading?

A few months ago I was interviewing for a job inside the company I am currently in, I dont have a strong web development background, but one of the questions he posed to me was how could you improve this block of code.I dont remember the code block perfectly but to sum it up it was a web hit counter, and he used lock on the hitcounter.
lock(HitCounter)
{
// Bla...
}
However after some discussion he said, lock is good but never use it in web applications!What is the basis behind his statement? Why shouldnt I use lock in web applications?
Is their a wayin sql server 2005 to change some type of setting on a data table so that it can not be updated or inserted into?
My problem is that I have a data table that is somehow being populated by an application. I have looked through all of the stored procs, views, functions and the C# code itself. I can't find out where or how it is populating a certain data table. So I figure if I can somehow make the table non updateable, then I can find out where the insert/update is occuring.
This would all occur in a test environment of course.
I'm developing an ASP.NET forms webapplication using C#. I have a method which creates a new Order for a customer. It looks similar to this;
private string CreateOrder(string userName) {
// Fetch current order
Order order = FetchOrder(userName);[code]....
The problem here is, it is possible that 1 customer in two requests (threads) could cause this method to be called twice while another thread is also inside this method. This can cause two orders to be created.
How can I properly lock this method, so it can only be executed by one thread at a time per customer?
I tried;
Mutex mutex = null;
private string CreateOrder(string userName) {
if (mutex == null) { [code]....
This works, but on some occasions it hangs on WaitOne and I don't know why. Is there an error, or should I use another method to lock?
What I'm looking to do is lock the application so the admin can do maintenance for however long. All i want to do is be able to click a button on a "maintenance" page and it makes it so anyone who attempts to use the system and anyone who is already in the system is redirected to a page, if they try to do anything, that says the site is down for maintenance.
on postback, on redirect, etc. No Access until that button is clicked again to unlock.
