 ic.Name = "cImg";
 ic.Width = 50;
 dtGrCustBal.Columns.Add(ic);
 foreach (DataGridViewRow row in dtGrCustBal.Rows)
 {
      DataGridViewImageCell cell = row.Cells[10] as DataGridViewImageCell;
      cell.Value = Properties.Resources.icon_payment_cash_small;       
 }

Call Child from MDIParent

 CustomerBalance ChildCustBal = new CustomerBalance();
 ChildCustBal.MdiParent = this;

Answer 1

When the image is bound in the form load event handler, in case of MDIChild the value of the DataGridViewImageCell is again reset to null by the time form is shown and you don't see any image. When its not MDChild then the cell value is retained and you see the image. I am not clear why the reset is happening in case of MDIChild.

Subscribe to the form's Shown event and move your image binding code to that event handler. It works in both normal and MDIchild use cases.

Try this, Use your project Namespace, when retrieving the image from Resource Folder.

DataGridViewImageColumn ic = new DataGridViewImageColumn();
ic.HeaderText = "Payment";
ic.Image = null;
ic.Name = "cImg";
ic.Width = 50;
dtGrCustBal.Columns.Add(ic);
foreach (DataGridViewRow row in dtGrCustBal.Rows)
 {
  DataGridViewImageCell cell = row.Cells[10] as DataGridViewImageCell;
  cell.Value ="your namespace".Properties.Resources.icon_payment_cash_small;       
 }
