If the combo is bound, you have to add the row to the data source.

Hi Mike,

how to insert a Row in UltraCombo i have already bind dataset

ulcombo.DataSource = dscoram;

ulcombo.DataBind();

now i want to add extra row like value is "***********"

how can i add like wise in .net Dropdown we have option like

ddl.item.insert(0,listitem("*****"));

how can i achieve in ultracombo pls advice

Hm, this is pretty confusing to discuss in a forum thread.One odd thing I notice is that you are binding the Text property of the UltraCombo. That's a little unusual. You would probably be better off using the Value instead.

Perhaps you could post a small sample project demonstrating the problem?

>> I'm still a little unclear on what you are binding in terms of the editor portion of the control.

I assume you are binding the Value property of the UltraComboEditor. Are you binding it to an instance of a class? Or a property on your class? <<

And I am not clear on what you mean by binding to an instance of a class or a property of a class :)

I believe it is the property of the class.

Here is relevant code from the designer. Let me know if you want additional code.

It is a little different from the example I described...but "Dimension" is bound to a ProductDimension (string) property on the business object. The business object has its own datasource called RequestItemBindingSource. 

The business object has a "ProductSize" (string) property, which I am trying to set when the dropdown is clicked using the ValueChanged event.

Dim UltraGridBand1 As Infragistics.Win.UltraWinGrid.UltraGridBand = New Infragistics.Win.UltraWinGrid.UltraGridBand("ProductSizeInfo", -1)

Dim UltraGridColumn1 As Infragistics.Win.UltraWinGrid.UltraGridColumn = New Infragistics.Win.UltraWinGrid.UltraGridColumn("Id")

Dim UltraGridColumn2 As Infragistics.Win.UltraWinGrid.UltraGridColumn = New Infragistics.Win.UltraWinGrid.UltraGridColumn("Size")

Dim UltraGridColumn3 As Infragistics.Win.UltraWinGrid.UltraGridColumn = New Infragistics.Win.UltraWinGrid.UltraGridColumn("Dimension")

Me.SizeUltraCombo.CheckedListSettings.CheckStateMember = ""

Me.SizeUltraCombo.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.RequestItemBindingSource, "ProductDimension", True, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged))

Me.SizeUltraCombo.DataSource = Me.ProductSizeBindingSource

.....

Me.SizeUltraCombo.Name = "SizeUltraCombo"

Me.SizeUltraCombo.Size = New System.Drawing.Size(121, 22)

Me.SizeUltraCombo.TabIndex = 23

Me.SizeUltraCombo.ValueMember = "Dimension"

I'm still a little unclear on what you are binding in terms of the editor portion of the control.

I assume you are binding the Value property of the UltraComboEditor. Are you binding it to an instance of a class? Or a property on your class?

If you are binding it to a single property on the class, then this seems like it should work okay. But if you are binding to the class instance itself, then I could see how this might cause a problem, because when you select an item from the list, that item on the list would be assigned to the Value of the UltraComboEditor. In which case, setting the ShirtSize on it would be redundant - since it would already be an instance of the class that has the same property settings. And when if it sends notifications, the combo might be re-selecting the item on the list that matches it and thus causing a recursive loop.
