数据网格中的圆角(需要尽快提供帮助) [英] Rounded Corners in a data grid (help needed asap)

问题描述

我不知道为什么我无法正确输入查询内容. :(:((

这是我关心的问题:在Windows应用程序中，对于数据网格，我需要圆角.

*我希望网格具有圆角，而不是单元格.

例如，如果它是矩形，则数据网格的所有4个角都应为圆形.

I donno why i am unable to put my query properly. :( :((

Here is my concern : In a windows application,, For a data grid , I need rounded corners.

* I want the grid to have rounded corners , not the cells .

For instance if it is in rectangular shape , all the 4 corners of the data grid should be in rounded shape.

推荐答案

这应该相当容易，具体取决于圆你想要的角落.

您所要做的就是以所需的任意形状创建一个GraphicsPath并将控件的Region属性设置为该GraphicsPath.

此处有一个示例示例 [

This should be fairly easy, depending on quite how round you want the corners.

All you have to do is create a GraphicsPath in whatever shape that you want and set the Region property of the control to be that GraphicsPath.

There is an example of the principle here[^] and if you follow the link at the bottom to example 8.4 you will find one that does it for a Control subclass.

You will also need a RoundedRectangle drawing class but I suggest that you google for that as there are so many of them out there, pick one you like.

非常感谢Henry，但我需要信息详细地.我莫名其妙地难以理解.

以下是实现wrt表单的技术

Thanks a lot Henry but i need info in detail. I somehow had difficulty in understading.

Below is the technique for implementation wrt forms

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;


namespace RndCorner
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            Region = System.Drawing.Region.FromHrgn(CreateRoundRectRgn( 0, 0,Width-10, Height-10, 20, 20));

        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
        [DllImport("Gdi32.dll", EntryPoint = "CreateRoundRectRgn")]

        private static extern IntPtr CreateRoundRectRgn(
            int nLeftRect, // x-coordinate of upper-left corner
            int nTopRect, // y-coordinate of upper-left corner
            int nRightRect, // x-coordinate of lower-right corner
            int nBottomRect, // y-coordinate of lower-right corner
            int nWidthEllipse, // height of ellipse
            int nHeightEllipse // width of ellipse
            );
    }
}

*网格有相同的方法

* Same way is there any way for grid

几乎完全相同应该起作用.

Almost exactly the same should work.

namespace RndCornerGrid
{
    public partial class MyCustomDataGridView : DataGridView
    {
        public MyCustomDataGridView()
            : base()
        {
            Region = System.Drawing.Region.FromHrgn(CreateRoundRectRgn( 0, 0,Width-10, Height-10, 20, 20));
        }

        [DllImport("Gdi32.dll", EntryPoint = "CreateRoundRectRgn")]
        private static extern IntPtr CreateRoundRectRgn(
            int nLeftRect, // x-coordinate of upper-left corner
            int nTopRect, // y-coordinate of upper-left corner
            int nRightRect, // x-coordinate of lower-right corner
            int nBottomRect, // y-coordinate of lower-right corner
            int nWidthEllipse, // height of ellipse
            int nHeightEllipse // width of ellipse
            );
    }
}

然后以常规方式将MyCustomDataGridView实例(或您决定调用的任何实例)添加到表单中.

Then add an instance of MyCustomDataGridView (or whatever you decide to call it) to your form in the normal way.
