<p>i've populated a dropdownlist control with different text properties but each text properties had THE SAME value (text property was A, value properties is blah,text property was B, value properties is blahblah, etc... )</p>

<p>ASP.net only checks value properties on postback and because ALL values were the same (for
testing reason) this little annoying behavior happened. Is there a work around? does this mean you can't never have the value to be the same? </p>

Sounds like you are working on the wrong event. Try
SelectedIndexChanged
.
Ensure you also have the
```
AutoPostBack
```
property set to
```
True
```
.

OK, so I got digging on this since I was curious :)
There is a "problem" when databinding with non-unique values.
So, firstly, I publicly apologise for saying otherwise.
To replicate:
ASPX
```
```
<asp:DropDownList ID="myDDL" runat="server" AutoPostBack="True">
    </asp:DropDownList>
    <asp:Label ID="lblSelItem" runat="server"Text="Currently Selected Item: 0"></asp:Label>
    <asp:Label ID="lblSelVal" runat="server" Text="Currently Selected Value: X"></asp:Label>
```
```
Code-Behind
```
```
List<string> MyData()
    {
        List<string> rtn = new List<string>();
        rtn.Add("I am the same value!");
        rtn.Add("I am the same value!");
        rtn.Add("I am the same value!");
        rtn.Add("I am the same value!2");
        return rtn;
    }

    protected void Page_Init()
    {
        if (!Page.IsPostBack)
        {
            // Load the Data for the DDL.
            myDDL.DataSource = MyData();
            myDDL.DataBind();
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        // Display the Currently Selected Item/Value.
        lblSelItem.Text = "Currently Selected Item: " + myDDL.SelectedIndex.ToString();
        lblSelVal.Text = "Currently Selected Value: " + myDDL.SelectedValue;
    }
```
```
Run, changing the values in the DropDownList. Note that a PostBack does not occur.
When looking at the Source, I realised that we need to explicitly set the "
```
value
```
" attribute for the
```
<option>
```
elements generated by the server control, which lead me to do something like:
New Code-Behind
```
```
Dictionary<string, string> MyTwoColData()
    {
        Dictionary<string, string> rtn = new Dictionary<string, string>();
        rtn.Add("1", "I am the same value!");
        rtn.Add("2", "I am the same value!");
        rtn.Add("3", "I am the same value!");
        return rtn;
    }

    protected void Page_Init()
    {
        if (!Page.IsPostBack)
        {
            // Load the Data for the DDL.
            Dictionary<string, string> data = MyTwoColData();

            foreach (KeyValuePair<string, string> pair in MyTwoColData())
            {
                myDDL.Items.Add(new ListItem(pair.Value, pair.Key));
            }

            myDDL.DataBind();
        }
    }
```
```
This explcitly sets the values to the "1", "2", "3" etc making them unique, while still displaying the correct data within the list.
Obviously, you can change this to work with single-column lists but just running through a for loop and using the value of
```
i
```
or something.
As to good workarounds with DataSets, not sure.
Realistically, would we present a list of options with the exact same values to the user?
I personally think not, which is probably why this "problem" hasn't been addressed :)
Enjoy!
PS:
Oh, I should also add, if you want to use the text value in the "fix" then change it to
```
SelectedItem
```
rather than
```
SelectedValue
```
