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> public int PageSize { get; set; } /// <summary> /// 总记录数 /// </summary> public int DataSoureCount { get; set; } /// <summary> /// 总页数 /// </summary> public int PageCount { get; set; } /// <summary> /// 当前记录行 /// </summary> public int CurrentPageIndex { get; set; } /// <summary> /// 取得或者设置数据控件的自定义列名 /// </summary> public List<string> gdvColHeaderText { get; set; } /// <summary> /// 取得或者设置绑定控件的数据集 /// </summary> public DataTable GetGridDataSoure { get; set; } /// <summary> /// 绑定数据到控件中 /// </summary> public void DataBaind() { dgv.DataSource = GetGridDataSoure; lbSoureCount.Text = DataSoureCount.ToString(); lbPageCount.Text = this.PageCount.ToString();

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 = 25; int CurrentPageIndex = fgivItem.CurrentPageIndex == 0 ? fgivItem.CurrentPageIndex += 1 : fgivItem.CurrentPageIndex += 0; 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) > 1 ? ((totalCount / fgivItem.PageSize) + 1) : (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();
