[英]How display images in datagridview? c#
I am developing an application in C # for desktop using Visual Studio Express 2010. 我正在使用Visual Studio Express 2010在桌面C#中开发应用程序。
I have a table in MySQL called Products with 3 fields: 我在MySQL中有一个名为Products with three fields的表:
ID -> Product_Name -> product_image
ID - > Product_Name - > product_image
The field product_Image
stores the image path in my hard drive (not the image itself) 字段
product_Image
将图像路径存储在我的硬盘中(而不是图像本身)
An example of a record would be: 记录的一个例子是:
0001 --- Mousepad XYZ ---- c:\\images\\mousepad.jpg
0001 ---鼠标垫XYZ ---- c:\\ images \\ mousepad.jpg
I wonder how fill a datagridview
that shows the ID, Produt name, and - especially - the product image
for each record in my SQL query. 我想知道如何填充显示
ID, Produt name, and - especially - the product image
的datagridview
ID, Produt name, and - especially - the product image
我的SQL查询中每条记录ID, Produt name, and - especially - the product image
。
All the examples I found were used manual data inserts, but I am looking for an example to fill the datagridview with data from a SQL query, not a manual insertion. 我找到的所有示例都使用了手动数据插入,但我正在寻找一个示例,用SQL查询中的数据填充datagridview,而不是手动插入。

Thank you for help, but could not directly apply the solutions. 感谢您的帮助,但无法直接应用解决方案。
I already have a datagridview on my form, I have no need to create in runtime. 我已经在我的表单上有一个datagridview,我不需要在运行时创建。
I need something like that (I'll write a generic way) 我需要这样的东西(我会写一个通用的方法)
returnMySQL = "select * from products";
while (returnMySQL)
{
fill datagrid with ID, product name, product image
}
Use following Code: 使用以下代码:
Bitmap img;
img = new Bitmap(@"c:\images\mousepad.jpg");
// Create the DGV with an Image column
DataGridView dgv = new DataGridView();
this.Controls.Add(dgv);
DataGridViewImageColumn imageCol = new DataGridViewImageColumn();
dgv.Columns.Add(imageCol);
// Add a row and set its value to the image
dgv.Rows.Add();
dgv.Rows[0].Cells[0].Value = img;
You can add images with the following way: 您可以使用以下方式添加图像:
//you need to perform some parsing to retrieve individual values of ID, Name and ImagePath
string path = @"c:\images\mousepad.jpg";
string ID = "0001";
string Product_Name = "Mousepad XYZ";
dataGridView1.Rows.Add(ID, Product_Name, Bitmap.FromFile(path));
You can Doing this simple way 你可以这样做
SqlConnection conn=New SqlConnection("SERVER=127.0.0.1;DATABASE=bdss;UID=sa;PASSWORD=1234");
SqlDataAdapter adpt = new SqlDataAdapter("select * from products",conn);
DataTable dt = new System.Data.DataTable();
adpt.Fill(dt);
int count = dt.Rows.Count;
dataGridView1.DataSource = dt;
