Then i want to click on image for re sizing it.How can i do it.Is it possible? if yes, Please someone help me.

<pre lang="C#">//Fill page with dynamic controls showing products in database
    private void GenerateControls()
    {
        //Get all coffeeObjects from database
        ArrayList coffeeList = Connectionclass.GetCoffeeByType(&quot;%&quot;);

        foreach (Coffee coffee in coffeeList)
        {
            //Create Controls
            Panel coffeePanel = new Panel();
            
            Image image = new Image { ImageUrl = coffee.Image };            
            Literal literal = new Literal { Text = &quot;&lt;br /&gt;&quot; };
            Literal literal2 = new Literal { Text = &quot;&lt;br /&gt;&quot; };
            Label lblName = new Label { Text = coffee.Name };
            
            
                
            Label lblPrice = new Label
            {
                Text = String.Format(&quot;{0:0.00}&quot;, coffee.Price + &quot;&lt;br /&gt;&quot;),
                CssClass = &quot;ProductsPrice&quot;
            };
            TextBox textBox = new TextBox
            {
                ID = coffee.Id.ToString(),
                CssClass = &quot;ProductsTextBox&quot;,
                Width = 60,
                Text = &quot;0&quot;
            };

            //Add validation so only numbers can be entered into the textfields
            RegularExpressionValidator regex = new RegularExpressionValidator
            {
                ValidationExpression = &quot;^[0-9]*&quot;,
                ControlToValidate = textBox.ID,
                ErrorMessage = &quot;Please enter a number.&quot;
            };

            //Add controls to Panels
            coffeePanel.Controls.Add(image);
            coffeePanel.Controls.Add(literal);
            coffeePanel.Controls.Add(lblName);
            coffeePanel.Controls.Add(literal2);
            coffeePanel.Controls.Add(lblPrice);
            coffeePanel.Controls.Add(textBox);
            coffeePanel.Controls.Add(regex);

            pnlProducts.Controls.Add(coffeePanel);
        }

如何在此处创建点击事件，以便在动态创建的图像控件上重新调整图像大小？与c＃asp.net

What I have tried:

How can i create click event here for re sizing image on dynamically created Image control? with c# asp.net

推荐答案

private void GenerateControls()
{
    Button button = new Button();
    button.BackgroundImage = Image.FromFile("coffee.png");
    button.BackgroundImageLayout = System.Windows.Forms.ImageLayout.None;
    coffeePanel.Controls.Add(button);
    button.Click += new System.EventHandler(this.button1_Click);
}

private void button1_Click(object sender, EventArgs e)
{
    MessageBox.Show("Clicked !");
}

如果您不想看到按钮边框，请按如下方式设置属性：

If you don't want to see the button borders, set the properties as follows:

button.FlatStyle = FlatStyle.Flat;
button.FlatAppearance.BorderSize = 0;
