Setting the back ground image of Buttons in an Array

[MarwaAlSagheer]

 
private void ChangeButtonsBackgroundimage(string[] NamesOfImageList,string FolderName)
    {
     try
      {
        ArrayList Arr_Button = new ArrayList();
        Arr_Button.Add(this.button1);
        Arr_Button.Add(this.button2);
        Arr_Button.Add(this.button3);
 
        for (int i = 0; i < NamesOfImageList.Length; i++)
        {
           Button TempButton = new Button();
           string FileName = FolderName + @"\" + NamesOfImageList[i] + ".bmp";
           FileName = Get_ImagePath(FileName);
           TempButton.BackgroundImage = Image.FromFile(FileName);
            Arr_Button[i] = TempButton;
 
       }
     }
     catch (Exception ex)
     { }
}
 

Buttons after this function doesn't appear the Background image while I am trace code I found that all property values of TempButtone including Backgroundimage was set to Arr_Button[i] ,BUT why it doesn't appear ??

Thanx in Advance .

Because the button that you've added to the array isn't the button in the Controls collection of the form. In your loop you are just creating a new button object and setting the background of that. The button on the form is a different object.

You'll need to change your code to remove the temporary button objects you are creating:

 private void ChangeButtonsBackgroundimage(string[] NamesOfImageList, string FolderName)
        {
            try
            {
                List<Button> buttons = new List<Button>();
                buttons.Add(this.button1);
                buttons.Add(this.button2);
                buttons.Add(this.button3);
 
                for (int i = 0; i < NamesOfImageList.Length; i++)
                {
                    string FileName = Path.Combine(FolderName, NamesOfImageList[i]);
                    buttons[i].BackgroundImage = Image.FromFile(FileName);
 
                }
            }
            catch (Exception ex)
            { }
        }

((Arr_Button[i])as Button).BackgroundImage= TempButton.BackgroundImage;
