Why doesn't toolstriplabel's backcolor property change during design time or run time?

I need to have a toolstrip label and its back color changed during runtime, but no matter what I do. It just won't change its backcolor, even though they give option to change its backcolor. Why is that and how do you get its backcolor property to change during runtime or design time? Thanks in advance, This is affected by the ToolStrip's RenderMode setting. Only when you change it to System will the BackColor property have an effect. The other renderers use theme colors. You are probably not going to like System very much, but you can have you cake and eat it too by implementing your own

问题 I have a ToolStrip in a C# application that I set the background color to Transparent. This reveals the underlying form's color but unfortunately the ToolStrip border is still visible. I've implemented a Custom Renderer and overridden the DrawBoarder method to not draw anything but that seems to apply to all of the contained buttons as well (i.e the menu on drop down buttons are also drawn without a border). So I'm stuck. What's the best way to draw transparent the entire ToolStrip but leave

Showing a tooltip on a non-focused ToolStripItem

ToolStripItems show Active highlighting when you mouse over them, even if the form they are in is not in focus. They do not, however, show their tooltips, unless the form is focused. I have seen the ToolStrip 'click-though' hack . Anyone know how to make a ToolStripButton show its tooltip when its parent form is not in focus? Thanks! The problem is that the ToolStrip "controls" like ToolStripButton or ToolStripDropDownButton don't inherit from Control. For now I addressed the problem by focusing the ToolStrip whenever a user hovers over a button. The button's MouseHover event is fired too late

StatusStrip label not visible when text too long

为君一笑 提交于 2019-12-04 03:09:02
I have a StatusStrip docked to the bottom of a C# Form, it contains a label, the text in it displays fine, except when there is longer length of text then it does not display at all, and I have to widen the form and then all of a sudden it appears. Is it possible to show it in the form below: This is a very long tex... So that the user knows that the app is showing something and then he can widen it himself, because when it is not visible at all, it does not indicate anything to user. You can create a custom renderer based on ToolStripProfessionalRenderer and override OnRenderItemText method

What's the deal with the ToolStrip's RenderMode property?

你说的曾经没有我的故事 提交于 2019-12-03 12:25:49
问题 I never quite understood what this property was designed for. I can see that it visibly changes the design of the toolstrip and I find that setting it to System on Windows XP makes it fit much better with the WinForms style. Is there some deeper meaning here? Does the way in which the control is rendered change at all and which mode would you recommend using? Thanks. 回答1: The RenderMode property allows the developer to precisely control the display of the ToolStrip (or ContextMenu). When you

How to remove this strange visual artifact in the corner of ToolStrip Winforms control?

Here is the picture that shows the problem. Take a look at the bottom right corner. Anyone knows how to get rid of it? Setting LayoutStyle to VerticalStackWithOverflow fixes it but also centers the items horizontally which I don't want. I just want a vertical stack like in the pic, but without that black line in the bottom right corner. In the properties bar, set "RenderMode" to "System" or use .RenderMode = System.Windows.Forms.ToolStripRenderMode.System; Doing this will change the .BackColor to "Control" but you can change that after if you want. Sorry for being late to the party, but the

Invoking the click method of a button programmatically

问题 Simple problem (I think): I want to be able to invoke a click method on a predefined object, specifically, the bindingNavigatorDeleteItem button on the standard c# BindingNavigator . I need to intercept the delete so that I can verify that the record is allowed to be deleted. If it is, I want to invoke the aforementioned click event which does a nice job of deleting said record. If the record is not eligible for deletion, I want to abort the delete. An engineering colleague of mine suggests
