Hi all,

I want to add the selected element from one listbox to another listbox and remove also on button click event >(button text for add) and <(button text for remove).

Also I need to add all the element from one listbox to another and remove also on button click event >>(button text for add all) and <<(button text for remove all).

I want to do this with Javascript.

Please help me as I have to do this by today.

Hey Varsha,

Use this code. This code has a ability to move the Selected Items from source to target. You can alter it as you like.

function AddItem(src,target){            
    for (i=src.length-1; i>=0; i--){
        if (src[i].selected){                    
            for (j=0; j < target.options.length; j++){                    
                if (src.options[i].text.toUpperCase() < target.options[j].text.toUpperCase()) 
                    break;
            }
            var oOptions = document.createElement("option");            
            target.options.add(oOptions,j);
            oOptions.value=src.options[i].value;
            oOptions.innerHTML=src.options[i].innerHTML;
            src.options.remove(i);                     
        }
    }
}

                Response.Clear();<br />
                Response.Buffer = true;<br />
                Response.ContentType = "application/vnd.ms-excel";<br />
                Response.Charset = "";<br />
                string sep = "";<br />
                foreach (DataColumn dc in dt.Columns)<br />
                {<br />

                    {<br />
                        Response.Write(sep + drow[count].ToString());<br />
                        sep = "\t";<br />

                    Response.Write("\n");<br />

What you are asking here is really basic, you simply take the input value from the login form then execute a simple query against DB to select the value. There are tons of tutorials out there that you can learn, you might also download the starter kits from the Microsoft ASP.NET site to learn from them.

I followed the article here http://www.kirupa.com/net/sql_asp_introduction.htm

everything compiles ok but when it get to opening the database I get error message
An attempt to attach an auto-named database for file C:\Path\Games.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share

I do not have any other databases with the same name and it is on the C drive so leads me to believe for some reason it can not open the database.

could someone please help me with this.
Thanks

ok i figured out what was wrong, .net 2.0 needed to be reinstalled, my app now runs but does not write to the database, is there something wrong with my code to write to the database?

SqlConnection connection;
protected void Page_Load(object sender, EventArgs e)
{
connection = new SqlConnection(ConfigurationManager.ConnectionStrings["GameConnection"].ConnectionString);
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
SqlCommand command = new SqlCommand("INSERT INTO gameTable(gameName, gamePlatform) VALUES (@id_gameName,@id_gmaePlatform)", connection);
SqlParameter nameContent = new SqlParameter("@id_gameName", SqlDbType.VarChar);
nameContent.Value = txtName.Text;
command.Parameters.Add(nameContent);

SqlParameter platformContent = new SqlParameter("@id_gamePlatform", SqlDbType.VarChar);
platformContent.Value = txtPlatform.Text;
command.Parameters.Add(platformContent);

connection.Open();
command.BeginExecuteNonQuery();
connection.Close();

You make an asynchronous call to insert data, but you close the connection right after that then how data can be inserted into DB. You might also double check the parameter name gmaePlatform as well.

I have a GridView that displays rows of pictures along with text that describes the pictures. When I click on the picture I would like another page to display. How do I write an event for that, or can I configure the Imagefield in the GridView to do this? Thanks.

minhpc_bk31-Jan-07 14:09

AFAIK, the ImageField does not allow you to define the event handler in the field markup, instead you'll need to use the RowCreated/RowDataBound event of the GridView control and try to get reference to the Image control, then register your event handler script. Another option is to use the Image control with the TemplateField in lieu of the ImageField and you can easily add the event handler for the Image control in the template.

You shouldn't need any event handlers, a template field with an image link will do the trick.

You can't get only a date. The DateTime structure is used to handle dates and times, and there is no Date structure wihtout time. The time is always there, even if it's 0:00, it's still there. It's no problem, though, as you choose what you want to display when you convert the DateTime value to a string.

The formatting string that you use in the call to ToString determines the format. The "d" string specifies the use of a short date format. The short date format is depending on the culture, so you should specify a FormatInfo or CultureInfo object to determine the culture to be used.

Is there any way to handle event(maybe some custom) raised by ASP.NET page in outer application(of course in .NET platform)? I am running Windows Form and start ASP.NET server from form. And data received from web should be processed in form too.
