gridview,gridview获取选中行的值
在GridView中编辑控件怎么使用。
这个简单 选择gridview控件 然后属性 看到那个闪电符号点一下 双击RowEditing这个 然后进入后台 写如下代码 GridView1.EditIndex = e.NewEditIndex;//使当前行进入编辑状态 BindData();//重新绑定数据 这个不能忘 然后 进入编辑状态后还有更新和取消事件粘贴一段给你看看 /// summary
/// 取消编辑事件
/// /summary
/// param name="sender"/param
/// param name="e"/param
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
isbool = false;
BindData();
}
/// summary
/// 编辑事件
/// /summary
/// param name="sender"/param
/// param name="e"/param
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex; BindData();
}
/// summary
/// 更新事件
/// /summary
/// param name="sender"/param
/// param name="e"/param
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{//更新事件中获取值的方法如下 string linkname = ((TextBox)GridView1.Rows[e.RowIndex].Cells[0].FindControl("TextBox1")).Text.Replace("'", "").Trim();//获取第一列中TextBox1控件的值string linkurl = ((TextBox)GridView1.Rows[e.RowIndex].Cells[1].Controls[0]).Text.Replace("'", "").Trim();//获取第二列的值 这个是编辑状态下 自动生成的控件获取方法上面那个是编辑模板里面的控件 }
gridview控件的功能是什么
本文将由达内的讲师详细为您介绍关于的相关常识。 我们在很多的第三方控件中都会发现有点击列头进行排序的功能，其实，在GridView控件中也是可以实现的，下面我们就看看如何在GridView控件中实现排序的示例。 以下为实现在GridView控件排序功能的全部代码，各位只需复制粘贴到vs中即可运行。 前台代码： asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False" CellPadding="3" OnSorting="GridView1_Sorting" Columns asp:BoundField DataField="身份证号码" HeaderText="用户ID" SortExpression="身份证号码" / asp:BoundField DataField="姓名" HeaderText="用户姓名" SortExpression="姓名"/ asp:BoundField DataField="员工性别" HeaderText="性别" SortExpression="员工性别"/ asp:BoundField DataField="家庭住址" HeaderText="家庭住址" SortExpression="家庭住址"/ /Columns
如何在GridView中实现多选
GridView实现跨页多选，参考如下：
JS 前台：
//GridView中实现多选效果
function?CheckAllC(oCheckbox)?{
????var?GridView1?=?document.getElementById('gvDataList');
????for?(i?=?1;?i??gvDataList.rows.length;?i++)?{
????????GridView1.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked?=?oCheckbox.checked;
????}
}
后台：
1：GridView翻页PageIndexChanging事件中调用获取多选主键信息,还需要判断一下，翻页之前是否已经有数据选中。具体方法如下:
方法如下：
#region 存储GridView翻页数据主键
??????? /// summary
??????? /// 存储GridView翻页数据主键
??????? /// /summary
??????? private void RememberOldValues()
??????? {
??????????? Dictionarystring, string list = Session["SelectedObject"] as Dictionarystring, string;
??????????? if (list == null)
??????????? {
??????????????? list = new Dictionarystring, string();
??????????? }
??????????? foreach (GridViewRow row in gvDataList.Rows)
??????????? {
??????????????? CheckBox cb = (CheckBox)row.FindControl("chkSelect");
??????????????? string user = gvDataList.DataKeys[row.RowIndex].Value.ToString();
????????????????if (Session["SelectedObject"] != null)
??????????????????? list = (Dictionarystring, string)Session["SelectedObject"]; //很重要
??????????????? if (cb.Checked)
??????????????? {
??????????????????? if (!list.ContainsKey(user))
??????????????????? {
??????????????????????? list.Add(user, "null");
??????????????????? }
??????????????? }
??????????????? else
??????????????? {
??????????????????? if (list.ContainsKey(user))
??????????????????? {
??????????????????????? list.Remove(user);
??????????????????? }
??????????????? }
??????????????? if (list != null list.Count 0)
??????????????????? Session["SelectedObject"] = list;
??????????? }
??????? }
??????? #endregion
附带GridView自带分页：
#region? 分页
??????? protected void gvDataList_PageIndexChanging(object sender, GridViewPageEventArgs e)
??????? {
??????????? RememberOldValues();
??????????? // 得到该控件
??????????? GridView theGrid = sender as GridView;
??????????? int newPageIndex = 0;
??????????? if (e.NewPageIndex == -3)
??????????? {
??????????????? //点击了Go按钮
??????????????? TextBox txtNewPageIndex = null;
//GridView较DataGrid提供了更多的API，获取分页块可以使用BottomPagerRow 或者TopPagerRow，当然还增加了HeaderRow和FooterRow
??????????????? GridViewRow pagerRow = theGrid.BottomPagerRow;
if (pagerRow != null)
??????????????? {
??????????????????? //得到text控件
??????????????????? txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
??????????????? }
??????????????? if (txtNewPageIndex != null)
??????????????? {
??????????????????? //得到索引
??????????????????? newPageIndex = int.Parse(txtNewPageIndex.Text) - 1;
??????????????? }
??????????? }
??????????? else
??????????? {
??????????????? //点击了其他的按钮
??????????????? newPageIndex = e.NewPageIndex;
??????????? }
??????????? //防止新索引溢出
??????????? newPageIndex = newPageIndex 0 ? 0 : newPageIndex;
??????????? newPageIndex = newPageIndex = theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;
//得到新的值
??????????? theGrid.PageIndex = newPageIndex;
//重新绑定
??????????? BindItems(0, NodeID, strSearch);
??????? }
??????? #endregion
2：点击提交按钮时，需要获取下GridView中的多选主键ID
#region 获取单选按钮选中的主键ID
??????? /// summary
??????? /// 获取单选按钮选中的主键ID
??????? /// /summary
??????? /// returns/returns
??????? private void GetPkID()
??????? {
??????????? Dictionarystring, string list = Session["SelectedObject"] as Dictionarystring, string;
??????????? if (list == null)
??????????? {
??????????????? list = new Dictionarystring, string();
??????????? }
??????????? foreach (GridViewRow row in gvDataList.Rows)
??????????? {
??????????????? CheckBox cb = (CheckBox)row.FindControl("chkSelect");
??????????????? string user = gvDataList.DataKeys[row.RowIndex].Value.ToString();
??????????????? if (cb.Checked)
??????????????? {
??????????????????? if (!list.ContainsKey(user))
??????????????????? {
??????????????????????? list.Add(user, "null");
??????????????????? }
??????????????? }
??????????????? else
??????????????? {
??????????????????? if (list.ContainsKey(user))
??????????????????? {
??????????????????????? list.Remove(user);
??????????????????? }
??????????????? }
??????????? }
??????????? ViewState["SelectedObject"] = list;????
??????? }
??????? #endregion
