Multi-Row Autosize Scrollable FlowLayoutPanel


I have 50 images. I need to add these images in FlowLayoutPanel, 30 images for 1st row after that wrap row and 20 images in second row. So I also need to show scrollbars on control.

I am dividing video into frames(images) and shown in FlowLayoutPanel. When I upload first video below are the code to set image :

for (i = 1; i < len - 1; i++)
{
    ImagePanel mybt = new ImagePanel(storagePath + words[0] + "_" + 
                                     i + ".jpg", words[0] + "_" + i + ".jpg");
    flowLayoutPanel1.Controls.Add(mybt);
}

After that when I upload second image I want to show images like in first row we have first video images after break I need to show second video upload images. If anybody knows how it can possible.


Solution

  • To get the result like you see in screenshot:

    • Put your FlowLayoutPanel in a Panel with AutoScroll property set to true
    • Set AutoSize property of your FlowLayoutPanel to true
    • Set WrapContent property of your FlowLayoutPanel to true (Default)
    • Set AutoScroll property of your FlowLayoutPanel to false (Default)
    • When adding controls you can use SetFlowBreak to break the flow of controls for those one you need.

    Screenshot

    enter image description here

    Code

    private void button1_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < 20; i++)
        {
            var btn = new Button() { Text = i.ToString() };
            if (i == 5 || i==15 )
                this.flowLayoutPanel1.SetFlowBreak(btn, true);
            this.flowLayoutPanel1.Controls.Add(btn);
        }
    }
    

    Here I am breaking the flow, at 5 and 15.
