问题 I am generating a dropdown list in codebehind and cannot get the selectedindexchanged event to fire automatically. It works fine when put directly into the ASPX page, but I need it to be in the codebehind. This doesn't work: var deptList = new DropDownList { ID = "deptList", DataSource = departments, DataTextField = "deptname", DataValueField = "deptid", AutoPostBack = true, EnableViewState = true }; deptList.SelectedIndexChanged += new EventHandler(deptList_SelectedIndexChanged); deptList

ASP.NET - Inline vs. Code-Behind

If it works, it works, but I can't

Convert a single file aspx to code behind

由 社会主义新天地 提交于 2019-12-21 12:05:14
问题 I'm working on a web site (not a web application) in VS 2008 .Net 3.5 and it uses the single file .aspx model where the server code is included in the head portion of the html instead of using a .aspx.cs code behind page. I'd like to quickly convert the files to use the code-behind model, but so far the only way I can do this is by removing the file, creating a new, code-behind aspx page of the same name, then manually copying in the aspx related code to the .aspx page and the server code to
