So your problem, if I understand correctly, is that you need to attach an integer to a combo box item. This is pretty easy:

private class MyComboBoxItem
{
    public readonly string Text;
    public readonly int Value

    public MyComboBoxItem(string text, int value)
    {
        this.Text = text;
        this.Value = value;
    }

    public override string ToString()
    {
        return this.Text;
    }
}

// Code to add the "France" item to the combo box
MyComboBoxItem france = new MyComboBoxItem("France", 5);
myComboBox.Items.Add(france);

// The event handler that handles selection changed event.
void myComboBox_SelectedValueChanged(object sender, EventArgs e)
{
    MyComboBoxItem selectedItem = (MyComboBoxItem)myComboBox.SelectedItem;
    int value = selectedItem.Value;
}

You can use ComboBox.Text for the text to display and its ComboBox.SelectedValue.

In binding, you can use DispalyMember for text display and ValueMember for the corresponding value.

There are so many ways...are you planning on storing the images in a database? Search SQL images on this site, it should point you in the right direction.

My mistake, I didn't see the asp.net part of your original request. Guess I expected a question dealing with asp.net would be posted to the ASP.NET forum

Change the type of the combobox to a dropdownlist. You will find it in the properties.

NotSupportedException was unhandled

hello, I got this exception on the first line of this code in the designer:
//
// pictureBox1
//
this.pictureBox1.Image = ((System.Drawing.Image)(resources.GetObject("pictureBox1.Image")));
this.pictureBox1.Location = new System.Drawing.Point(3, 3);
this.pictureBox1.Name = "pictureBox1";
this.pictureBox1.Size = new System.Drawing.Size(222, 94);

Basically i just added a picturebox to contain a jpg image. this form is common to all the applications and they work fine with the others. but the app im working on throw me back the error message. Im using VS2005 CF .net 2.0 so do the other app (which are written by me too). So i don't get it. why the others are fine but this later doesn't work.

Any suggestion?

Missing System.Drawing.Point

I have been working on a large project in VS2005, and I have come to need the System.Drawing.Point struct, and instead of having loads of stuff in the System.Drawing namespace I only have:

System.Drawing.Dimension<br />
   System.Drawing.Dimension2D

I have been trying to work out what has switched this off but cannot fathom what it could be. Could some kind soul point (sorry for the pun) me in the direction of how to resolve this iritating issue, please.

Thanks.

I feel so stupid. As soon as I had logged this message I noticed that my project References was very low. I have now added a reference to the System.Drawing namespace and we are back in business. God knows why this became un-referenced!

I am optimizing application written in C#. It is apparently exceeding the user objects limit in XP.
Now I want to trace where all these user object are being created by the application.
Is there any tool available which would serve the purpose?
Or any other way?

Every bit counts
