问题 We have asp.net application using DevExpress 9.3 version and we have to upgrade to 12.1, what is the best way to upgrade ? 回答1: Use the Project Converter tool for this purpose. See the Upgrade Notes topic for details. 回答2: Generally you just install the new version, then open the solution in the newer version, that's how Visual Studio, etc. works. They should run in parallel and make backups, so trying won't be of any harm. 回答3: In Visual studio, click DevExpress -> Project Converter ->

I have found the following: CheckedComboBoxEdit.Properties.GetCheckedItems() which returns an object, but I cannot find any reference on what I

问题 Suppose I have an DevExpress ASPxTextBox whose id is "instrument". I want to access the value of the text box at client side. So I need to write a javascript. If it was a normal asp text box, I could have accessed the text box by writing code like var instrumentElement = document.getElementById('<%=instrument.ClientID%>') But the same approach is not working for the DevExpress's Text Box. How can I access an ASPxTextBox ? I am using Developer Express Version 7.2. Here is some more thorough

问题 We have run into a strange bug that we're having problems debugging. We have a MDI workspace that uses Microsoft CAB, DevExpress components, and .Net 3.5.

Can someone point me in the right direction? 回答1: Source: Project Wizard documentation The Choose Theme tab allows you to specify a theme to be applied

问题 The TcxRadioGroup component of DevExpress has a very nice way to specify items. You can specify a Caption and a Value (and a Tag) for each TcxRadioGroupItem.
