How to add Buttons in WinForm in Runtime?

I have the following Code :

public GUIWevbDav()
{
    InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
    try
    {
        //My XML Loading and other Code Here

        //Trying to add Buttons here
        if (DisplayNameNodes.Count > 0)
        {
            for (int i = 0; i < DisplayNameNodes.Count; i++)
            {
                Button folderButton = new Button();
    开发者_JS百科            folderButton.Width = 150;
                folderButton.Height = 70;
                folderButton.ForeColor = Color.Black;
                folderButton.Text = DisplayNameNodes[i].InnerText;

                Now trying to do  GUIWevbDav.Controls.Add
                (unable to get GUIWevbDav.Controls method )

            }
        }

I dont want to create a form at run time but add the dynamically created buttons to my Current Winform i.e: GUIWevDav

Thanks

Just use this.Controls.Add(folderButton). this is your form.

Problem in your code is that you're trying to call Controls.Add() method on GUIWevbDav which is the type of your form and you can't get Control.Add on a type, it's not a static method. It only works on instances.

for (int i = 0; i < DisplayNameNodes.Count; i++) 
{ 

    Button folderButton = new Button(); 
    folderButton.Width = 150; 
    folderButton.Height = 70; 
    folderButton.ForeColor = Color.Black; 
    folderButton.Text = DisplayNameNodes[i].InnerText; 

    //This will work and add button to your Form.
    this.Controls.Add(folderButton );

    //you can't get Control.Add on a type, it's not a static method. It only works on instances.
    //GUIWevbDav.Controls.Add

}

You need to work with Control.Controls property. In Form Class Members you can see Controls property.

Use it like this :

this.Controls.Add(folderButton);  // "this" is your form class object.
