I tried this out and I do not get the results you are describing.

I ran this code and selected item 2 from the list. I see a 2 in the Combo and the ValueChanged event fires with a 2.

Then I typed in a "4", and the ValueChanged event fired with a "4".

I am, of course, using the latest service release of the controls.

The control has to return the text you typed.When DropDownStyle is set to DropDown, it's perfectly valid to type something into the combo that is not on the list and you, the developer, have to be able to get the value from the combo.

So if this was returning null in some older version of the controls, then that was a serious bug and must have been fixed.

Hi Mike,

You might have not aware of that...Check the sample with Infragistics 8.2 version dlls. First select some valid value from the list then type invalid data and check the value.. it  comes null.

here is the sample code.

private void ultraCombo1_ValueChanged(object sender, EventArgs e)
{
         Debug.WriteLine(ultraCombo1.Value.ToString(), "ValueChanged");
}
private void Form1_Load( object sender, EventArgs e )
{
        DataTable dt = new DataTable( "Test" );
        dt.Columns.Add( "ID", typeof( Int32 ) );
        dt.Columns.Add( "Code", typeof( string ) );
        dt.Rows.Add( 1, "A");
        dt.Rows.Add( 2, "B");
        dt.Rows.Add( 3, "C");
        ultraCombo1.DataBindings.Clear();
        ultraCombo1.SetDataBinding( dt, null);
}

execute this code with 8.2 version dlls.

Hi Dhananjay,

I'm not sure what earlier versions you are referring to. As far as I can remember (and I have been working here at Infragistics since before the UltraCombo existed), the control has always worked this way.

If you type in a value that is not on the list, the control's Value property returns the Text you typed in.

If you set teh DropDownStyle to DropDownList, then the user will be unable to type in an invalid value, and if you set the value in code to something that is not on the list, it probably returns null. But this behavior has not changed in any version as far as I know.

Hi Mike,

Why ultraCombo.Value is coming as invalid data? in earlier version dlls if we type invalid data ( If ValueMember does not match ) then Value was coming null. now its coming as typed invalid data... I think, earlier functionality was correct.. combo.Text should come as Typed text and Value should be null because ValueMember did not match.. Do you guys fix this Or this is new feature...?

Thanks
