Hi Shunman,

After inspecting your code I found that you are not setting e.Item.Text of RadComboBox. Please try the following code snippet in ItemDataBound event of RadComboBox.

VB:

Protected Sub RadComboBoxProduct_ItemDataBound(sender As Object, e As Telerik.Web.UI.RadComboBoxItemEventArgs)

Dim labelProduct As Label = DirectCast(RadComboBoxProduct.Items(e.Item.Index).FindControl("RadComboBoxItemProduct"), Label)

Dim labelProductStatus As Label = DirectCast(RadComboBoxProduct.Items(e.Item.Index).FindControl("RadComboBoxItemProductStatus"), Label)

labelProduct.Text = DirectCast(e.Item.DataItem, DataRowView)("ProductName").ToString()

labelProductStatus.Text = DirectCast(e.Item.DataItem, DataRowView)("CodeName").ToString()

e.Item.Value = DirectCast(e.Item.DataItem, DataRowView)("FirmProductNo").ToString()

e.Item.Text = DirectCast(e.Item.DataItem, DataRowView)("CodeName").ToString()

End Sub

Hope this helps.

Thanks,
Princy.
