This is javascrpt 101, the main thing is you need to write script that creates variables that contain the client side names of the checkboxes.
What else do you need help with ?

You probably would have to modify connection string, to point it to mdb file.

Hi,
I have an array like this:
string[3] arr;
arr[0]="ck1";
arr[1]="ck2";, arr[2]= "ck3"..
Now In my aspx page I have 3 checkboxes. Now I want to set the Checkbox text from the array arr values (for the first checbox text as arr[0]. like this) instead of setting the text while declaring the checkboxes.
Thanks in advance.

|
|
|
there is a read/write property "Text" for checkbox. So what is the problem is setting the text ?
You can set it like
checkbox1.Text = arr[0].ToString()

I can't seem to get to display the results from a gridview. The code compiles but it only shows 'no records' when I display the webpage. Any help would be greatly appreciated. I am thinking that maybe the information for 'typename' and 'dataojecttypename' are incorrect. What exactly should these two contain?
Here is my code in part:
[DataObjectMethod(DataObjectMethodType.Select)]
public static List<userdata> getAllUsers()
{
MySqlCommand cmd = new MySqlCommand();
DB_Connection conn = new DB_Connection();
try
{
cmd.Connection = (MySqlConnection)conn.DBConnect();
cmd.CommandText = "getAllUsers";
cmd.CommandType = CommandType.StoredProcedure;
cmd.ExecuteNonQuery();
MySqlDataReader dr;
dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
List<userdata> userList = new List<userdata>();
while (dr.Read())
{
UserData user = new UserData();
user.UserID = Convert.ToString(dr["User_ID"]);
user.UserLastName = Convert.ToString(dr["User_Last_Name"]);
user.UserFirstName = Convert.ToString(dr["User_First_Name"]);
}
dr.Close();
return userList;
<asp:objectdatasource id="ObData" runat="server" typename="users"
="" oldvaluesparameterformatstring="original_{0}" selectmethod="getAllUsers" dataobjecttypename="userdata">
<asp:gridview id="GridView1" action="databind" runat="server" datasourceid="ObData" autogeneratecolumns="False" emptydatatext="<b>No Records</b>" allowpaging="True" datekeynames="User_Id">
<columns><asp:boundfield datafield="User_Id" headertext="User_Id" sortexpression="User_Id">
<asp:boundfield datafield="User_Last_Name" headertext="LastName" sortexpression="User_Last_Name">
<asp:boundfield datafield="User_First_Name" headertext="FirstName" sortexpression="User_First_Name">

Your method returns userList, which has only been instantiated and has not been initialized. You might want to put some values in that list for the datagrid to bind to. I'm assuming thats what you're binding the datagrid with.
Next time, please put the code in <pre></pre> tags to make it easier to read.

List userList = new List();
You create an instance of a List object but you don't add any items to it.
while (dr.Read())
{
UserData user = new UserData();
user.UserID = Convert.ToString(dr["User_ID"]);
user.UserLastName = Convert.ToString(dr["User_Last_Name"]);
user.UserFirstName = Convert.ToString(dr["User_First_Name"]);
}
For each iteration of the loop, you create a new UserData object and populate it with data from the current record returned by the DataReader. However you don't do anything with each UserData object. After each iteration of the loop the UserData object will go out of scope and be lost. You should add these objects to some sort of collection data structure if you want to retain them.

Thanks, Paul. You pointing this out made me realize that I had forgotten a very important line of code, mainly: userlist.add(user);
It is working like a charm now.

I am developing an home page which can be access from 5 countries. Based on user location (which i don't know it could be Country A, B, C , D or E) i need to change home page accordingly. By default we will have country A.
My boss says try to explore culture...but i have no idea for the same...Could you please show some directon....
Thanks
Thanks

You can create a CultureInfo object from a culture identifier or culture name. Example:
CultureInfo culture = new CultureInfo("en-GB");
You just have to find out what culture the user preferres. The Accept-Language header in the HTTP headers might be one way to find this out.
You use the CultureInfo object whenever you format any data that is culture dependant, for example in the string.Format or double.ToString methods. Example:
labelPrice.Text = price.ToString("C2", culture);

Yes, of course. You are showing the culture that the server is using.

Check the dataset that is returned from from the fill method 
"Session("Formats") = dsFormat"
Don't store your dataset in a session variable, it is bad practice and a performance drain.
"selectText = "select format from Formats where fID='" + num + "' and format <> 'Other'"
Don't use in-line sql. Use stored procs, or at least parameterized commands.
And don't hard code the connection string, even if it is a test app, get in the habit of using good programming practices.

Thank you Mark, I will try changing the session variables thing later, once I get this to work.
How can I check if the dataset returned is empty or not. Can you plz help me with the code for it?
|
|
|
|
|
And once when I find that the result set is empty, I must fill the grid with a custom message.
Can you please help me how.

No. A little research on your own will be more valuable then giving you the code. I'll give you a hint though. How many rows are there in a DataTable?
