问题 I have this text box on the bottom of my app, and I need it to stay there no matter what (much like a sticky positioning in css).

问题 I have a jquery autocomplete menu for book searches. The autocomplete is working fine, but I would still like the option of doing a search query (POST data) from the text typed in the text box, by pressing enter, and ignoring the autocomplete suggestions.

问题 So I have a textbox in C# (Using .NET forms) where I am going to accept a users string for some input. This string already has text (arguments) at the beginning that will exist at the beginning of the string no matter what. It must be there. I want them to be aware of this, but not be able to delete the words from the textbox (so they wont think theyve deleted it already when its going to be there anyways) So these first arguments must not be able to be deleted or edited. Any text after these

3 月，跳不动了？>>> textBox经常用来显示程序的运行状态或者消息，如何让他自动滚动呢? winform的比较简单,但是WPF C#的以前没接触过，我百度了很多都没找到理想的代码。后然才无意发现，其实非常简单，在显示消息代码下加一条自动滚动到底部的语句即可: TextBox1 .ScrollToEnd(); （如果要显示垂直滚动条设置 VerticalScrollBarVisibility="Auto",如果不显示设置为Hidden ）我用的程序代码如下（我的用了多线程，所以看起来挺复杂）： this.btnStart.Dispatcher.Invoke(new Action(() => { if (rtxtProgramRunStatus.LineCount > 100) { rtxtProgramRunStatus.Clear(); } //大于100行清除记录 rtxtProgramRunStatus.AppendText(string.Format("{0},ONU:{1}show mac 执行完成，第{2}轮，累计扫描{3}台.\r\n", DateTime.Now.ToString(), onuIp,Round,CheckedOnuCount+1));//插入运行结果 rtxtProgramRunStatus.ScrollToEnd(); //自动滚动到底部

Handling ENTER button in TextBox, ASP.NET

阅读更多关于 Handling ENTER button in TextBox, ASP.NET

问题 I have the following problem in ASP.NET: there is a form that contains a textbox and a button next to it that is supposed to be pressed by the user after filling the box (sample on http://www.burnthespam.info, click "Pick your one", or when using ReCaptcha in a popup). Often, instead, users press ENTER key to submit the form. This doesn't cause the click event on the button to be triggered and possibly cause an unexpected behaviour. In burnthespam, I "tried" to solve by checking if there is
