Hello,

I am developing a window application.
At the time of rendering images in DataGridViewImageColumn , only first image is showing in all rows.This is my code...

C#

private void BindGrid()
{
    DataSet ds = objStaff.GetStaff(1);

    if (ds != null)
    {
        grdDetail.DataSource = ds.Tables[0];
        grdDetail.Columns["StaffId"].Visible = false;
        grdDetail.Columns["Image"].Visible = false;
        DataGridViewImageColumn img = new DataGridViewImageColumn();
        //int number_of_rows = grdDetail.RowCount;
    
        for (int i = 0; i < grdDetail.Rows.Count; i++)
        {
            img.HeaderText = "Image";
            img.Width = 80;      
            string imagePath = ds.Tables[0].Rows[i][1].ToString();
            Image image = Image.FromFile(imagePath);
            img.Image = image;        
            
            //grdDetail.Rows[i].Cells["Picture"].Value = image;
             grdDetail.Columns.Add(img);
        }
    
        grdDetail.Refresh();
    }
}

What should I do? Please help.

First of all use break point at this line :
string imagePath = ds.Tables[0].Rows[i][1].ToString();
And check you get different imagePath or same all then time.And check you grid view how you use image control in it.

You Can : (its works for me)
1. add a byte column to table of dataset
2. Add image in byte column
3. then bind data table with grid
as follows

C#

private void BindGrid()
{
    DataSet ds = objStaff.GetStaff(1);
 
    if (ds != null)
    {
            DataTable dtable = new DataTable();
            DataColumn dcol = new DataColumn("myImage");
          
            dtable = ds.Tables[0].Copy;
            dcol.AllowDBNull = true;
            dcol.DataType = System.Type.GetType("System.Byte[]");
            dcol.Caption = "myImage";

            dtable.Columns.Add(dcol);
            foreach (DataRow drow in dtable.Rows)
            {
               string imagePath = drow[1].ToString();
	       Image image = Image.FromFile(imagePath);
	       System.IO.MemoryStream ms = new System.IO.MemoryStream();
	       image.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); // your image format here
	       drow["myImage"] = ms.ToArray();
            }

        grdDetail.DataSource = dtable;
        grdDetail.Columns["StaffId"].Visible = false;
        grdDetail.Columns["Image"].Visible = false;
    }
}
