ASP.NET TextBox (HTML input field) populates with username automatically when form loads

问题 I have a TextBox control in a form which is still pulling in data when the HTML form renders. I tried setting the AutoCompleteType to "None" but I think that just controls whether or not it will find previously entered data for that field, not what actually fills into that input field when the page loads. Why would this textbox be pulling in data? It's causing another larger issue. This TextBox is inside of a control (*.ascx file). It's loaded from another control dynamically--not sure if

Verifying User Input

问题 My user will enter some bytes in a place like this. Yellow arrow points to his input, Orange arrow points to my button After about half an hour, I began to realize that this is far more tedious than I expected. Question: Am I going to have to write hundreds of lines of code to ensure that the user follows the rules ? The rules for the syntax in his input are... A hex byte Then a comma Then white space (maybe, at his option) Those three rules can be repeated as much as the user wants. For

You can enable/disable such behaviour FocusManager.IsFocusScope="True"/"False" 回答2: Here is another way. The selection will also remain highlighted. private void MyMethod() { TextBox txt = ...; txt

Loop through empty textbox until the textbox has data

我们两清 提交于 2019-12-13 09:47:27
问题 I'm sure there's a simple solution on this, but it escapes me. I have a form with three text boxes on it. Before the main code is run I want to make sure each text box has data in it. I've initialized "hasData" to be the variable that will decide if the code can move on or not. I evaluate hasData in a Do While loop but the code discovers there are text boxes without data and set hasData variable to "False". But then I'm in a continuous loop, the message box never goes away to allow you to
