Hi.. yes I already filled up a dropdown list coming from SQL data as my datasource. But I dont know how to code the second part that you are saying.
"Secondly on the selectedindex change event of the first dropdown list bind the second dropdownlist(getting the corresponding data from the database).
To fill the second dropdownlist you have to pass the selected items ID(i.e. departments ID) in order to get the correct set of records."
Can you show me in vb.net code? I really appreciate it. Thanks.

What you need to do in the second part is you have to get the ID value of the item selected in the department dropdownlist(when you would have bind the first dropdownlist then you would have assigned the text and value field, you need to get that value of the selected item). And once you are having that you can query to get the records associated with that department ID. And once you get the desired records you have to bind the second dropdown exactly like you have done with the first one. I think now it would have been clear.

Hi all,
In my Asp .net Application.. I need to store the date in a variable.. For that i wrote the following code
Dim thisDate, startDate, endDate As Date
Dim thisMonth, thisYear As Integer
thisDate = Now.Date
thisMonth = Month(thisDate)
thisYear = Year(thisDate)
If thisMonth = 1 Or 3 Or 5 Or 7 Or 8 Or 10 Or 12 Then
startDate = "1/thisMonth/thisYear"
endDate = "31/thisMonth/thisYear"
ElseIf thisMonth = 4 Or 6 Or 9 Or 11 Then
startDate = "1/thisMonth/thisYear"
endDate = "30/thisMonth/thisYear"
Else
startDate = "1/thisMonth/thisYear"
endDate = "28/thisMonth/thisYear"
End If
But it shows the error message as,
Cast from string "1/thisMonth/thisYear" to type 'Date' is not valid.
Please help me in this issue..

The Or operator doesn't work that way. You can't use it to compare one value to several values. You have to make each operand a complete condition.
JVVS wrote: startDate = "1/thisMonth/thisYear"
You can't use a variable inside a string. You have to concatenate the string values.
Why are you trying to create a string to be converted to a date? Use the constructor of the DateTime structure that takes year, month and day.

How can i check without or operator..

You don't have to do it without the or operator, you only have to use it correctly:
If thisMonth = 1 Or thisMonth = 3 Or thisMonth = 5 Or thisMonth = 7 Or thisMonth = 8 Or thisMonth = 10 Or thisMonth = 12 Then

Hi,
Can we access html controls created through javascript in ASP.NET code behind ?
var arrInput = new Array(0);
var arrInputValue = new Array(0);
function addInput() {
//arrInput.push(createInput(arrInput.length));
arrInput.push(arrInput.length);
//arrInputValue.push(arrInputValue.length);
arrInputValue.push("");
display();
}
function display() {
document.getElementById('parah').innerHTML="";
for (intI=0;intI<arrInput.length;intI++) {
document.getElementById('parah').innerHTML+=createInput(arrInput[intI], arrInputValue[intI]);
}
}
function saveValue(intId,strValue) {
arrInputValue[intId]=strValue;
}
function createInput(id,value) {
//alert(id);
return "<input type='text' id='test "+ id +"' onChange='javascript:saveValue("+ id +",this.value)' value='"+ value +"'><br>";
//alert(test);
}
function deleteInput() {
if (arrInput.length > 0) {
arrInput.pop();
arrInputValue.pop();
}
display();
}
Dynamic creation of input boxes
Add more input field(s)
Remove field(s)
<asp:button id="MySubmit" runat="server" text="submit">
Can i access the controls data in codebehind ? i dont see it getting enumerated in the Controls collection ?
foreach (Control c in Controls)
Response.Write(c.ClientID.ToString() + c.GetType().ToString() + "
");

I have an ASP page that is the basic 'home' location (called user_area.asp) for all of my clients who log into my website. In the user_area.asp page, it calls for some common elements with an #INCLUDE FILE statement that are standard and not variable. (Such as 'header_inc.asp' and 'footer_inc.asp')
If I have a field in my Cutsomer Data Base (.mdb) called 'Custom2' and that field would contain a URL to something like:
mysite.com / clients / clientname / client.asp
What I would need to do is be able to use the #INCLUDE FILE statement to call for the 'Custom2' field so that I could include the clients 'client.asp' within the 'user_area.asp' page.
This 'Custom2' variable in my database would change accrdingly to whomever logged into the system. Since none of the clients have the same exact download files, the 'Custom2' variable would always change and the #INCLUDE FILE statement would always point and display a seperate client.asp page withing the user_area.asp page.
Thoughts? Resolution?

I'm building a web accounting application in ASP.NET 2.0 using VS 2005 and SQL Express. I already developed a VB6 accounting app but re-developing in ASP.NET 2.0 is a bit difficult.
My problem is in making the form/web page look very much like the actual business form, say a sales invoice. In VB6 I could use the DBGrid control to add data but in ASP.NET 2.0 the GridView can only edit, select or delete. How to Create an Invoice-like Form in ASP NET 2.0 ?
I am at the moment trying to use a FormView for the invoice header so that I can rearrange the textboxes so that it looks like an invoice header (eg. invoice number, date on the right top edge, address on the left top edge, etc)
For the line item details (Stock Code, Description, Qty, Price and Amount) I put another FormView with a row of text boxes and an Insert link at the end and then a GridView just below it so that the columns are aligned with the input text boxes above. When users enter the input in the one-row text boxes above the grid, they can inserted into the grid row by row and the text boxes become blank again to accept new input.
I have tried to use the DetailView control to make my programming easier but I find no way to convert it into one single row rather than what it is now (1 column, a new rows for each field).
Anybody knows of a better way ?

I am trying to understand how to send HTML emails to the users. The content of the emails can vary according to the users, e.g.:
Dear [CustomerName]
Thanks for your orders. Your order number is [OrderNumber].....
How can I create / manage email content such as above.
I am also interested to know how does Amazon create their emails. Because the whole content of their emails is tailored for each individual customer.
Thanks

Hey,
Check out Syed Moshiur Murshed's tutorial for sending email using GMail[^].
in his tutorial you can see that one of the properties he configed was:
<br />
mailMsg.BodyFormat = MailFormat.Text;<br />
MailFormat is an enum that one of his options is "HTML" that sends the email in html format (as you asked) and by using the class MailMessage you can render a html code and send it to the customer..
something like:
<br />
string customerName = ".....";<br />
long customerId = 539482;<br />
string messege = "<html><body>Hello " + customerName + " your Id is " + customerId.ToString() + "</body></html>";<br />
and then by using the Body property in MailMessage you can set the mail's text to the messege
by using:
<br />
mailMsg.Body = messege;
Hope I helped...
Good luck 
Tal Kain.

Hello,
I have an Imagebutton with the folowing tag:
<asp:ImageButton runat="server" CommandArgument="0" ID="btnNota0" meta:resourcekey="img1" SkinID="Note0" OnClick="btnNote_Click" />
I need to create this button at runtime and adding it with the Controls.Add method.
The aspx file have a resx file in the LocalResources folder with the key "img1.Tooltip" to have the tooltip of the button localizable.
My problem is how can I create the button at runtime and use the same resource key?
Is this simple?
Thanks to everyone for the replies.

Hi everybody!
I have a UserControl and all it's functionality is placed in an assembly (DLL). The UserControl generates a form with a number of TableRows containing a title, a input field and some other information. My problem is that every TableRow has a Tooltip set, and I don't want to show this. How on earth can I access the TableRow in the UserControl from the main-page's Page_Load and disable the Tooltip? My wish it that i somehow can access all the Tables TableRow's and disable them in a loop (like foreach (TableRow t in Table-placed-in-DLL-and-placed-in-usercontrol)...). Is it possible? Or do I have to solve this with javascript (hope not)?
Thank you!

If you have developed the user control then provide a public property to disable/enable tooltip by using a for each loop that loops through all tablerows and assigns a blank string
If you didn't develop, see whether the table is exposed as a property and manipulate it using server side code

Krishna, how did you implement ICallbackEventHandler for 2.0? Can you post your code? I can help you if I see your code first.
