I am trying to place on a form a dynamic column of images - the name of the image is from a database. The code below compiles OK but does not display the pictureboxes. Any help would be appreciated
___________________________________________________________________________________________________________________________
 DataTable dt = dset.Tables[0];
           
 DataRow[] foundRows;
 string strExpr = "true";

 // Sort ascending by column named Overlap.

            string strSort = "Overlap ASC";

// Use the Select method to find all rows matching the filter.

            foundRows = dt.Select(strExpr, strSort);

            int rcount=dt.Rows.Count;
//create the correct number of pictureboxes in the array

            PictureBox[] pboxes = new PictureBox[rcount];

//initialise counter
 int outcount = 0;

//loop through each datarow

            foreach (DataRow drow in foundRows)
            {
               
              //find the top position for the picturebox

              int pos_image = 10 + (outcount * 220);

                //load the bitmap

                string bmap_location = drow.ItemArray[6].ToString();          // drow.ItemArray[6] is the filename
                try
                {
                   
           
                    Bitmap bmap = new Bitmap(bmap_location);
           
                    PictureBox tempbox = new PictureBox();


                    //get the longest dimension and modify the picture box so smaller but with correct aspect ration
                   
                   if (bmap.Width >= bmap.Height)
                    {
                        tempbox.Width = 200;
                        decimal dival1 = Decimal.Divide(200,bmap.Width);
                        tempbox.Height = Convert.ToInt32(dival1*bmap.Height);
                    }
                    else
                    {
                        tempbox.Height = 200;
                        decimal dival1 = Decimal.Divide(200, bmap.Height);
                        tempbox.Width = Convert.ToInt32(dival1 * bmap.Width);
                    }

                    //each photo 20 pixels from the form left hand side
                    tempbox.Left = 20;

                    //picture top to derived location
                    tempbox.Top = pos_image;

                   // load the bmp into the image
                    tempbox.Image = bmap;

                    //make visible
                    tempbox.Visible = true;


                    //load the array picturebox with the created picturebox
                    pboxes[outcount] = tempbox;

                    outcount++;

                }
                catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message.ToString());
                   
                    }


            }

It seems you never add your picture boxes to th form.

Try to add like:

myForm.Controls.Add(tempbox )
0
