Too bad. javascript is what runs on the client, so that's what you have to use.

In addition:

It is however possible to set the AutoPostback property of the TextBox to true and wait on the TextChanged event. However this event fires only when the user leaves the TextBox.

However, not exactly what you asked for and the user experience is rather bad.

Yeah, I didn't suggest it for that reason. My experience on these forums is if you mention in passing something that you should never do, the OP will proceed to do it.

SmartNavigation in asp.net 2.0

Hi All,
SmartNavigation is obsolete in 2.0. MaintainScrollPositionOnPostBack is added. But there are some features which were more in SmartNavigation, absent in the present version.
One of the most useful feature was, not entering browser history items for post backs on same page. I tried lot of ways to implement the same using javascript, but i failed. I found that SmartNavigation uses FRAMES (IFRAME) for doing this.
Can this be done in 2.0 ? Is there direct property of page to enable this feature only ? SmartNavigation was for IE only, is there a more generic solution for the same ?

Any help will be greatly appreciated.

Thanks

Pb with RequiredFieldValidator

jpeg26-Jul-07 23:32

26-Jul-07 23:32

Hello everybody

Maybe one of you can help me.
I have an ASP.NET page that contains :
- a TextBox
- a RequiredFieldValidator for this TextBox.
- an HtmlImage

I added an attribute 'onclick' to my HtmlImage. It executes a javascript fonction that fill the TextBox with a default text.

If I do the following :
- click on the TextBox
- remove the text in the TextBox
- click the image

Then the textBox looses the focus and calls the validator which detects that the text has been changed and is now empty. So the validator displays the validation message (a '*' char).

After that, the javascript function is called (event onclick) and set the TextBox text to the default text. But the validation message is always displayed on the web page whereas the TextBox has got a valid value.

I have tried to use focus() in my javascript function but it was unsuccessful.

Can I call the validation function in my own javascript function to force the RequiredFieldValidator to re-evaluate the text in the textbox ? Or have you got any other idea ?

Thank you for help.

Thank you for your reply Pathan but It does not seem to work properly
I tried the following jscript on my button :

<br />
var oTxt = eval(document.all[objText]);<br />
var sVal = "25/12/2007";<br />
oTxt.value = sVal;<br />
<br />
// oTxt.onchange.call();<br />
oTxt.blur();<br />

The js code does not hide the validation message that has been being shown until TextBox looses the focus.

Hi all,

I have one webservice conating one method like this

using EmployeeInformation;
[WebMethod]
public Employee getEmployeeInfo()
{
Employee emp = new Employee();

return emp;
}

Where Employee is Name of the Class .
I have on dll name EmployeeInformation which contains definition of Employee Class in following manner.

namespace EmployeeInformation
{
public class Employee
{
private ArrayList E_firstName;
private ArrayList E_LastName;

public Employee()
{
SqlConnection cnEmp = new SqlConnection(ConfigurationManager.AppSettings["EmpConnectionString"].ToString());
cnEmp.Open();

SqlCommand cmdEmp = new SqlCommand();
cmdEmp.Connection = cnEmp;
cmdEmp.CommandType = CommandType.Text;
cmdEmp.CommandText = "select E.FirstName,E.LastName from Employee E";

DataTable dtEmp = new DataTable();
SqlDataAdapter daEmpInfo = new SqlDataAdapter("select E.FirstName,E.LastName from Employees E", cnEmp);
daEmpInfo.Fill(dtEmp);

E_firstName = new ArrayList();
E_LastName = new ArrayList();

foreach (DataRow Emp in dtEmp.Rows)
{
E_firstName.Add(Emp["FirstName"]);
E_LastName.Add(Emp["LastName"]);
}

cnEmp.Close();
}

public Object[] Firstnames
{
get { return E_firstName.ToArray(); }
}
public Object[] LastNames
{
get { return E_LastName.ToArray(); }
}

}
}

Which returns Firstname and lastname of Employee from northwind database.

Where are these files ? If they are on the server, then it's kind of trivial, if they are on the client, it's not possible.

If you're moving files on the server, then you just need to render some representation of the possible paths a file can live in, and on postback, use the File class to move the file. Why do you want to do this ?

You need to make use of Rand() method available in SQL Server. This will generate random number. I presume that each of your question having unique id. First you need to find starting and ending question number. Then start a cursor, Find random number which comes in between starting and ending question id. Inside this loop you need to select question details for the randomly generated question id and insert values into one temporary table. Finally select your temporary table.

Using cursors is not advisable practice, but if no other methods are available you can choose this. D'Oh! | :doh:

You can't program the serial port in ASP.NET. .NET 2.0 has a serial port class, for windows apps.

Hi,

I have been given a task to monitor all user behaviour on our web site, this has to include capturing all values of any controls which have been changed.

I really want to create a standalone module which will do this for me. We have created our own controls - eg a IntegerTexBox that will only numbers, and a floatTextBox which will only accept decimals, and I am wondering if I could add method, or override an existing method, in these controls, to handle my task?

I am at a loss of where to start really Confused | :confused:

, here's hoping someone can maybe point me in the right direction? Tried to google and found articles, just none that can point me in the right direction.

Has anyone done something similar before?

Many thanks, in advance,

Janet

To capture the values of all controls, you indeed need to create your own control classes which capture changes in state and store them. Sounds like overkill to me.

If user is entering any dummy value before submitting the form, do you need to track that also. ? If so I think you need pretty big storage medium. Are you planning to store all these values in DB ?

DixonJM wrote:

Yes you need to do this to track details. Since your controls are custom written you have always a chance to write events on that. But honestly speaking, your requirement seems to be very big and tough to implement. If it is the case of tracking user visited pages, that will be easy. I found some articles here in CP which explains about tracking user visited pages.
