Hello,
i have one question regarding textbox update. What happens is i have used one textbox say txtbox1 and button btn1 in aspx page. And i have one usercontrol in ascx page. On the button btn click event, i am getting values from user contro to the txtbox1. And on the same button click, i am using that txtbox1 value to insert into the database. but Since its a same button click, though the value is showing in the txtbox1, it is not inserting into the database. So what can be the reason for that ? Is that because of not using postback thing or any other reason. I am using asp.net with sql server.

What do you mean by this? Does this mean you are using AJAX to get value from usercontrol to textbox and then textbox to DB?
Whatever the case is, did you debug it? What did you got?

Is it two client events working on the same button? If so, what is the order? Are they async? They need to be in order... synchronously.
Post a little code, if these doesnt help. The button click event part, the way you are binding the methods and whats in the menthod.

No error at all. Actually i have one user control in ascx page. And using that user control, i put that result in the textbox which is in aspx page. now the value which i am keeping from user control to that textbox is in button click event. now On the same button click, i am trying to use that textbox value for inserting into the database. but it is not sending that value to the database though once i click the button, that value is showing in that textbox. So just wondering is that because i didnt put the postback thing??

You need to be little more clear Suchita!
From what i got from your details, the flow should be:
1. Fill some value in Usercontrol ascx: ValueA
2. Press buttonA in ASPX parent page.
3. buttonA, brings ValueA in the textboxA of ASPX parent page
4. buttonA, send the ValueA in DB to store.
Now, if the sequence is right, they need to be SYNCHRONOUSLY, i.e. one after other.
Further, step 3 & 4 needs to be coded together in its handler. Add on if i missed something and also post a little part of your button click event.

you got it. But the problem is since the textbox is getting value and also textbox value is using for database in the same event, i think textbox value is not going to the database. But if i use the same thing in two events, its working fine. but i need that in a single event..

For that, please share the event code! Once you get the value in ASPX, you should be able to save it.

protected void btnSubmit_Click(object sender, EventArgs e)
{
WriteThisMessageToThePage1.sendMessageToThePage += delegate(string message){txtNeededDate.Text = message; };
WriteThisMessageToThePage2.sendMessageToThePage += delegate(string message){txtRequestDate.Text = message; };
cmd = new SqlCommand("INSERT INTO ProjectRequestInfo(ClientFName,ClientMName,ClientLName,Email,Extension,DepartmentName,ProjectTitle,ProjectDescription,DueDate,RequestDate,IntendedUsersAudience,SubmittedDate,NotificationTo) values('" + txtFirstName.Text + "','" + txtMiddleName.Text + "','" + txtLastName.Text + "','" + txtEmail.Text + "','" + txtExtension.Text + "','" + DrpDwnDepartmentList.SelectedItem.ToString() + "','" + txtProjectTitle.Text + "','" + txtProjectDescription.Text + "','" + txtNeededDate.Text + "','" + txtRequestDate.Text + "','" + txtIntendedUsers.Text + "','" + System.DateTime.Now.ToShortDateString() + "','" + getHighCnt + "')", conn);
conn.Open();
cmd.ExecuteNonQuery();
}
here i am getting value for txtNeededDate.text from message(i.e from usercontrol) and i am inserting the txtNeededDate.text to the database like that. It is not giving any error but it is not inserting value to database.

Could you just try putting a little delay after first two lines, before inserting in SQL?
like a dummy loop of 10,000 or so.
Or in debug mode, just put a breakpoint at cmd line and check what is the value of txtNeededDate.

Dummy loop is also not working...

From your code, there does not seem any problem.
One suggestion, yo could've public property in your usercontrol which gives the value that you want to update in textbox and use that property. This is cleaner and simple approach.
Debug your code and see where the problem lies.
Using the textbox to insert the data in DB should not be a problem. Also try using a local variable assign this first, then use this to insert in DB, might be you get the problem.

I tried using local variable too but the same problem...

Ya i tried with debug mode. textboxes are not getting values within that event. After that event, they are getting values.. So what can be done for such problems ??

Hi All,
I'm user VS 2005 and wanted to know if it's possible to create a user control that can be used in both a Windows Application and a WebSite?
I'm coding in C# with ASP.NET.
I'm wanting to create a control like the DateTimePicker, which is available when creating Windows Applications, but it doesn't seem to be available when creating WebSites. Please tell me if I'm wrong, this way I can build upon the existing control. Thanks.
If you know of any websites that might be useful, I would be very geratful if you shared them.
Thanks in advance.
Mel

Not possible, they are two separate environments.
