![]() ![]() The TextBox class adds several properties to the ones it inherits from TextBoxBase, as shown in the following table. Because it's possible to clear the undo buffer, you should check the CanUndo property before trying to undo operations. Text controls maintain an undo buffer, so it's possible to undo changes. The Lines property holds an array of String s that is used to represent the lines in a multiline edit control. Multiline text controls will use newline characters to break lines, whereas single-line controls will display newline characters as control characters (which usually display as a short vertical bar). Text boxes can be single-line or multiline, which is controlled by the Multiline property. Undoes the last clipboard or text change operation. Scrolls the control so that the caret is visible. Replaces the current selection with the contents of the clipboard. If false, they will scroll horizontally until a newline character is reached.Ĭlears the most recent operation from the control's undo buffer.Ĭopies the selected text to the clipboard. If true, multiline text boxes will word-wrap as necessary. Gets the length of the text in the control. Gets or sets the text displayed in the control. Gets or sets the length of the selection. Gets or sets the read-only status of the control. This enables you to size the text box so that it displays text correctly. Gets the preferred height in pixels for the current font. If true, the control is a multiline text box. Gets or sets a Boolean value representing whether the control's content has been modified. The default value is 0, which means that the length is limited only by the available memory. ![]() Represents the maximum number of characters that can be typed into a control. Gets or sets the collection of lines in a text box as an array of String s. If true, selected text in the control is dimmed when the focus passes to another control. Set to true if the last operation can be undone. Represents the background and foreground colors. ![]() If true, the control automatically resizes itself to fit its text. / of the control.If true, the Tab key will enter a tab character into the control instead of moving to the next control in the tab order. This.Renderer = new ToolStripProfessionalRenderer( This.RenderMode = ToolStripRenderMode.Professional Public partial class CustomToolStrip : ToolStrip First, we need to tell the control to render from our custom color table. Now, it is time to revisit our custom control and pull everything together. ![]() To persist user changes, we need to make sure the scope is set to User rather than Application (this is read only). The reason we are creating the settings file is so that we can persist changes. Go ahead and create a setting for each color item. Within the Properties folder in the Solution Explorer, there should be a ttings file. The reason I've instructed you to create the methods first is so we can copy and paste the method names into our Settings file. Return Īs you can see, the return values are set to. / public override Color ToolStripGradientEnd / /// Gets the ending color of the gradient / public override Color ToolStripGradientMiddle / /// Gets the middle color of the gradient / public override Color ToolStripGradientBegin / /// Gets the starting color of the gradient / public override Color ToolStripDropDownBackground / /// Gets the background color of the drop down / public override Color ToolStripContentPanelGradientEnd / /// Gets the ending color of the content panel gradient / public override Color ToolStripContentPanelGradientBegin / /// Gets the starting color of the content panel gradient / public override Color ToolStripBorder / /// Gets the border color of the control. Internal class CustomToolStripColorTable : ProfessionalColorTable Instead, I want to inherit from the class, as shown below. The file we just added inherits from the UserControl class. To create the custom control, simply add a new user control to the project. To begin, we need the following two things: Since each control is pretty much the same, I will just focus on the ToolStrip control. In my project, three different controls exist. I also wanted something I could use over and over again. Customizing the color schemes is fairly easy via code, but I wanted to edit the colors at design time. The old Windows look starts to get old after awhile. I wanted each UI to have its own custom color theme. Over the past few months, I've created UIs using an MDI form. We will look at the ProfessionalColorTable class as well as the ToolStripCustomRenderer class. This article was written to demonstrate how to customize the display of the ToolStrip, MenuStrip, and StatusStrip controls. ![]()
