winfrom dataGridView 自定义分页实现

Winfrom 基本处于忘光的阶段.先需要做个winfrom 的软件.然后自己扩展了DataGridView带分页的控件。废话不多说 上图先  

现在一步步实现其效果.

1.添加用户控件 上图即可知道布局以及怎么实现

2.代码如下

  #region 控件属性
 
        /// <summary>
        /// 页大小
        /// </summary>

3.如何使用

在页面在拖入控件.填充数据如下

 string sqlWhere = " where 1=1 and fState in(0,1) ";
 
            if (!string.IsNullOrEmpty(txtArtNo.Text))
            {
                sqlWhere += string.Format(" and fArtNo like '%{0}%'", txtArtNo.Text);
            }
            if (!string.IsNullOrEmpty(txtBarCode.Text))
            {
                sqlWhere += string.Format(" and fBarCode like '%{0}%'", txtBarCode.Text);
            }
            if (!string.IsNullOrEmpty(txtItemName.Text))
            {
                sqlWhere += string.Format(" and fItemName like '%{0}%'", txtItemName.Text);
            }
            if (ddlBigClassID.SelectedValue.ToString() != "-100")
            {
                sqlWhere += string.Format(" and fBigClassID = '{0}'", ddlBigClassID.SelectedValue);
            }
            if (ddlMidClassID.SelectedValue != null && ddlMidClassID.SelectedValue .ToString()!= "-100")
            {
                sqlWhere += string.Format(" and fMidClassID = '{0}'", ddlMidClassID.SelectedValue);
            }
            if (ddlSubClassID.SelectedValue != null && ddlSubClassID.SelectedValue.ToString() != "-100")
            {
                sqlWhere += string.Format(" and fSubClassID = '{0}'", ddlSubClassID.SelectedValue);
            }
 
            ItemBaseBLL bll = new ItemBaseBLL();
            fgivItem.PageSize = ;
            int CurrentPageIndex = fgivItem.CurrentPageIndex ==  ? fgivItem.CurrentPageIndex +=  : fgivItem.CurrentPageIndex += ;
            fgivItem.CurrentPageIndex = CurrentPageIndex;
            fgivItem.GetGridDataSoure = bll.GetDateSoure(sqlWhere, "fItemID", "fItemID,fBigClassName,fMidClassName,fSubClassName,fItemName,fArtNo,fBarCode,fImportPrice,fSalePrice,fPrice1,fInVeryPrice,fCostPrice,fStateText", fgivItem.PageSize, fgivItem.CurrentPageIndex);
            int totalCount = bll.GetCount(sqlWhere);
            fgivItem.DataSoureCount = totalCount;
            int totalPageNum = (totalCount % fgivItem.PageSize) >  ? ((totalCount / fgivItem.PageSize) + ) : (totalCount / fgivItem.PageSize);
            fgivItem.gdvColHeaderText = new List<string> {"商品编号", "商品大类", "商品中类", "商品小类", "商品名称", "商品货号", "商品条码", "进价", "售价", "活动价", "换购价", "成本价", "状态" };
            fgivItem.PageCount = totalPageNum;
            fgivItem.setSingleValue = "fItemID";
            fgivItem.IsVisibleFirstCom = true;
            fgivItem.DataBaind();
