try this,

foreach (DataListItem anItem in DataList1.Items)
        {
            CheckBox chk = ((CheckBox)anItem.FindControl("deleteRec"));
            if (chk != null)
            {
                if (chk.Checked)
                {
                    TextBox tmpTxtBox = ((TextBox)anItem.FindControl("ImageID"));
                    string imageID = tmpTxtBox.Text;
                    proxy.DeleteRecord("delete * from Image where IMAGE_ID=" + imageID + "");
                }
            }
        }

Solution 1

I guess this is a viewstate Issue am not sure, but has the page directive marked enable viewstate to false,

If yes try changing it to true.
