The issue is, you need to create them before page load for viewstate to be restored. It's better to not create them dynamically.

Thanks for reply.

In this application based on one dropdownlist box value, I am creating required number of dropdownlist box.this I have to do dynamically.

so is their any other way to get the value from dynamically created dropdownlist box.

There are many ways to do this functionality
1.you can have a repeater in that repeater control add all your dynamically created dropdowns, if you are showing them in same section then only you can use this .
2. Store the id that you have given to dropdown and check
in the Request object it will give selected value of that dropdown,
But if you are using Master Page/User control then you will have to give client ID,get that one by checking html content of the page.

I hope it will help you

please help me to resolve this issue.

below is the code to create dropdownlist dynamically.

protected void createddl(int surveyID, int attributeID)
   {
       ISession session = NHibernateSessionManager.Instance.GetSession();
       IQuery attributeValueQry = session.CreateQuery("from MasterValueEntity mve where TypeID='" + attributeID + "'");
       IList attributeValueList = attributeValueQry.List();
       IQuery labelValueQry = session.CreateQuery("from MASTERTYPEEntity mte where TypeID='" + attributeID + "'");
       IList labelValueList = labelValueQry.List();
       IQuery hierarchyValueQry = session.CreateQuery("from HierarchyEntity");
       IList hierarchyValueList = hierarchyValueQry.List();
       DropDownList list = new DropDownList();
       list.Items.Add("Select");
       Label label1 = new Label();
       if (attributeID == 0)
       {
           label1.Text = "Hierarchy";
           label1.Width = Unit.Percentage(60);
           label1.Height = Unit.Percentage(50);
           foreach (HierarchyEntity hierarchyEn in hierarchyValueList)
           {
               list.ID = "Hierarchy";
               list.Items.Add(hierarchyEn.Hname);
               list.Width = Unit.Percentage(65);
           }
           list.Items.Add("All");
       }
       else
       {
           foreach (MASTERTYPEEntity masterTypeEn in labelValueList)
           {
               list.ID = masterTypeEn.TypeName;
               label1.Text = masterTypeEn.TypeName;
               label1.Width = Unit.Percentage(60);
               label1.Height = Unit.Percentage(50);
           }

           foreach (MasterValueEntity masterValueEn in attributeValueList)
           {

               list.AutoPostBack = true;
               list.Items.Add(masterValueEn.TypeDesc);
               list.Width = Unit.Percentage(65);

           }
           list.Items.Add("All");
       }



       PlaceHolder1.Controls.Add(label1);

       PlaceHolder2.Controls.Add(list);


       session.Close();
       NHibernateSessionManager.Instance.CloseSession();
   }

Hi,
If i put dd/mm/year format in textbox means then how can i convert that ddmmyear format into mmddyear format?

string mashing, I guess.

Thanks for ur reply sir...

But i dont understand ur answer.

So can u give me solution for that problem?

you have a string, and you want to change it's format, so you need to take the string and reorganise it. use the split method to split based on the / then reorder the three items you get back, to get the format you want. Or just use int.tryparse to get the ints and build a date time from there, if that is what you need.

Except for mashing, there is a nicer way:

DateTime dt = DateTime.Now; //replace with your datetime.<br />
string mmddyear = dt.ToString("MMddyyyy");

see for more options: http://www.geekzilla.co.uk/View00FF7904-B510-468C-A2C8-F859AA20581F.htm[^]

Sorry for that previous post,was only a partial answer. Here is the complete answer

//Get input, parse it correctly.
string input  = "31/12/2005";
DateTime dt = DateTime.ParseExact(input, "dd/MM/yyyy", System.Globalization.CultureInfo.GetCultureInfo("en-US").DateTimeFormat);

//Show output in our format:
string output = dt.ToString("MMddyyyy"); // will give us 12312005

Hi,

I have a login page which takes the username and password and connects to the Oracle database. The login details are same as oracle db login details. If the user attempts 5 invalid logins to the application, the user id gets locked in both the application and the database. However, if the user is typing the same wrong invalid password consecutively for 5 times, the user id is not getting locked in the database. This means for the same set of userid and password, the post back is not working. Can you please explain and give a solution? We are using ASP.NET 1.0 with VB.NET. Thanks in advance!

Regards,

why would it ? I mean, it's still one attempt,right ?

I guess this means some component is doing this, it's not your own code ?

Hi
I am using the following statement:

cmdSearch.CommandText = "select doctitle, filename, characterization, hitcount from SCOPE
('" /dotNet "') where FREETEXT ( '" + searchText + "') ";

but it is showing an error for /dotnet, it has a problem with the /
How can I edit the query so it allows the /, is it a banned character so to speak

thanks

/ is used as an escape character. For example /" is how you put quotes in your string. Putting a @ at the start of the string turns these off, and will fix your code. Or you can use // to escape a /.

I am using the article below
http://www.codeproject.com/KB/aspnet/IndexingServer.aspx

and trying to include the following line:

FROM SCOPE(' SHALLOW TRAVERSAL OF ("/", "/Help") ')

but it wont allow me to add it as it says there is a syntax error, why would this be?

thanks!

string selectintranetquery = "select doctitle, filename, vpath, rank, characterization, hitcount
FROM SCOPE(' SHALLOW TRAVERSAL OF ("/", "/Myfile") ') where FREETEXT(Contents, '" + searchText + "') order by rank asc ";

for the reason I told you, but in reverse. C# can't tell when you mean a " to be in the string, because you're not escaping it.

string selectintranetquery = @"select doctitle, filename, vpath, rank, characterization, hitcount
FROM SCOPE(' SHALLOW TRAVERSAL OF (""/"", ""/Myfile"") ') where FREETEXT(Contents, '" + searchText + "') order by rank asc ";

note that you use "" to get quotes when using @.

No, it's not. You are thinking of the backslash character: \
