WPF: the style of control does not work unless the control template created for style

Here is content of xaml with the control template: <Style TargetType="{x:Type TextBox}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate> <Border Name=

Sorry. Below is my code: TextBox1.Text

Get the value of a scrollbar's scroll for a Winforms Text Box (C#)

由 不问归期 提交于 2019-12-25 03:30:51
问题 I am creating a Windows Form Application using C# I require a checkbox to be greyed out until the user scrolls to the bottom of a text box. How can I get the value of the textbox's scrollbar position? 回答1: This should be a RichTextBox so you can use its SelectionProtected property to ensure that the user cannot change the text. It does not have a Scroll event but that can be added by overriding WndProc() and detecting the WM_VSCROLL message. Checking if the last line is visible like @TaW does

How do you make a text box readonly using JavaScript

由 荒凉一梦 提交于 2019-12-25 02:43:39
问题 How can i make a text box readonly when a button is clicked using JavaScript? I have tried different scripts like: document.getElementById("text").readonly="on"; but since readonly is a Boolean i don't think it works. Would i use document.getElementById or something else? Can i make all of the text-boxes in a form readonly using one script or would i need a separate script for each text-box? Could this be done using CSS? Thank you! 回答1: document.getElementById("text").readonly='readonly';
