UltraCombo AutoCompleteMode.SuggestAppend problem
posted

Hello, Infragistics Team!

I use AutoCompleteMode.SuggestAppend!

1)Then i write some text in combo, it append my text, but after i press Enter, i get that Combo.Value == null and Combo.SelectedRow  == null (i try to catch this param in AfterCloseUp event). If i again open and close Combo, get right SelectedRow.

2)It was very unexpectedly for me, then after i write some text (for example 'bla-bla-bla'), which had not include in combo.datasoure, then combo.Value ='bla-bla-bla'. In previous version value was null in this situation.

Thanks. //Sorry for my English.

    1. This is because AfterCloseUp fires before the value is assigned. You can get around this using BeginInvoke to define a method to be called after AfterCloseUp has fired, at which time the Value and SelectedRow will have been assigned.

    Example:
    void ultraCombo_AfterCloseUp(object sender, EventArgs e)
    {
        this.BeginInvoke( new MethodInvoker(this.ultraCombo_AfterCloseUpAsync) );
    }

    void ultraCombo_AfterCloseUpAsync()
    {
        object val = this.myCombo.Value;
        UltraGridRow selectedRow = this.myCombo.SelectedRow;
    }

     

    2. As far as I know this has always been the case - the SelectedRow would return null, but the Value property returns the text in the edit portion. The exception to this rule is when the DropDownStyle property is set to 'DropDownList'.
