问题 I want to use a Web Browser to access a website that uses JavaScript on load. I understand that Web Browser is a wrapper of the current installed version of Internet Explorer.

阅读更多关于 Show controls added programmatically in WinForms app in Design view?

问题 Using Visual Studio (any version will do), is it possible for controls added programmatically (rather than via the Design view) to then be shown when switching back to the Design view? I've tried something ridiculously simple like: public Form1() { AddCtrl(); InitializeComponent(); AddCtrl(); } private void AddCtrl() { this.SuspendLayout(); this.Controls.Add(new TextBox()); this.ResumeLayout(false); this.PerformLayout(); } ...but to no avail. 回答1: Does the designer run my code? When a form

Custom browsable property for Form at design time

阅读更多关于 Custom browsable property for Form at design time

问题 I want to make a custom property for a windows form browsable during design-time but none of my efforts have panned out to success. The obvious solution would seem to be to set the browsable attribute to true: [Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Description("Custom Border Colour"), Category("Custom")] public Color BorderColour { get { return bCol; } set { bCol = value; } } But this doesn't work. I have done it numerous time for custom controls and it works like a

阅读更多关于 Click event for .Net (Windows Forms) user control

问题 This is probably a very simple question, but for some reason, even the right way to web search for the answer eludes me... I'm trying to create a user control that consists of a few labels and progress bars. However, I want the entire control to have a "Click" event that is raised no matter what item inside the control is clicked on. I've created a "HandleClick" procedure that is assigned to each control: private void HandleClick(object sender, EventArgs e) { // Call the callback function, if

Combining multiple Attributes to a single Attribute

阅读更多关于 Combining multiple Attributes to a single Attribute

On a control I am using multiple attribute properties: [Browsable(false)] [Bindable(false)] [EditorBrowsable(EditorBrowsableState.Never)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] [Obsolete("", true)] public new Boolean AllowDrop; I am using those properties on a lot of the other control properties as well. I am wondering if there is a way to reduce the amount of code to write each time. It would be nice if I could combine multiple attributes like this: [Hidden(true)] public new Boolean AllowDrop; Where the Hidden Property would include all the attributes above.

How can I get Visual Studio 2008 Windows Forms designer to render a Form that implements an abstract base class?

阅读更多关于 How can I get Visual Studio 2008 Windows Forms designer to render a Form that implements an abstract base class?

I engaged a problem with inherited Controls in Windows Forms and need some advice on it. I do use a base class for items in a List (selfmade GUI list made of a panel) and some inherited controls that are for each type of data that could be added to the list. There was no problem with it, but I now found out, that it would be right, to make the base-control an abstract class, since it has methods, that need to be implemented in all inherited controls, called from the code inside the base-control, but must not and can not be implemented in the base class. When I mark the base-control as abstract

阅读更多关于 How to make a DataTable from DataGridView without any Datasource?

问题 I want to get a DataTable from DataGridView of the Grid values. In other words DataTable same as DataGridView Values 回答1: Might be a nicer way to do it but otherwise it would be fairly trivial to just loop through the DGV and create the DataTable manually. Something like this might work: DataTable dt = new DataTable(); foreach(DataGridViewColumn col in dgv.Columns) { dt.Columns.Add(col.Name); } foreach(DataGridViewRow row in dgv.Rows) { DataRow dRow = dt.NewRow(); foreach(DataGridViewCell
