ASP.NET中访问DataGrid中所有控件值的方法
本文实例讲述了ASP.NET中访问DataGrid中所有控件值的方法。分享给大家供大家参考,具体如下:
<%@ Page Language="C#" %> <%@ import Namespace="System.Collections" %> <script runat="server"> void Page_Load(Object sender, EventArgs e) { if(!Page.IsPostBack){ ArrayList data = new ArrayList(); data.Add(new Person("Tom",33,true)); data.Add(new Person("Jhon",39,false)); data.Add(new Person("Mark",20,false)); data.Add(new Person("Linda",27,true)); MyDataGrid.DataSource = data; MyDataGrid.DataBind(); } } void GetValues_Click(Object sender, EventArgs e) { String Result = ""; foreach(DataGridItem dataGridItem in MyDataGrid.Items){ //Get name from cell[0] String Name = dataGridItem.Cells[0].Text; //Get text from textbox in cell[1] String Age = ((TextBox)dataGridItem.FindControl("AgeField")).Text; //Get Checked property of Checkbox control bool IsGraduate = ((CheckBox)dataGridItem.FindControl("IsGraduateField")).Checked; // get Values from Checkboxlist String Skills = ""; foreach(ListItem item in ((CheckBoxList)dataGridItem.FindControl("CheckBoxList1")).Items){ if (item.Selected){ Skills += item.Value + ","; } } Skills = Skills.TrimEnd(','); //Get RadioButtonList Selected text String Experience = ((RadioButtonList)dataGridItem.FindControl("RadioButtonList1")).SelectedItem.Text; //Get DropDownList Selected text String Degree = ((DropDownList)dataGridItem.FindControl("DropDownList1")).SelectedItem.Text; // Build String to show result. Result += Name; Result += " [Age -" + Age + "] "; if (IsGraduate){ Result += "Is Graduate , "; }else{ Result += "Is not Graduate , "; } Result += "Has Skills[" + Skills + "] , "; Result += "Has " + Experience + " Experience , And " ; Result += "Has " + Degree + " Degree." ; Result += "<br>"; } ResultField.Text = Result; } class Person{ String _Name; int _Age; bool _IsGraduate; public Person(String name,int age, bool isGraduate){ _Name = name; _Age = age; _IsGraduate = isGraduate; } public String Name{ get{return _Name;} } public int Age{ get{return _Age;} } public bool IsGraduate{ get{return _IsGraduate;} } } </script> <html> <head> </head> <body> <form runat="server"> <asp:DataGrid id="MyDataGrid" runat="server" AutoGenerateColumns="False"> <ItemStyle verticalalign="Top"></ItemStyle> <Columns> <asp:BoundColumn DataField="Name" HeaderText="Name"></asp:BoundColumn> <asp:TemplateColumn HeaderText="Age"> <ItemTemplate> <asp:TextBox id="AgeField" Columns="5" Text='<%# DataBinder.Eval(Container.DataItem,"Age") %>' runat="server"></asp:TextBox> </ItemTemplate> </asp:TemplateColumn> <asp:TemplateColumn HeaderText="Graduate"> <ItemTemplate> <asp:CheckBox id="IsGraduateField" Checked='<%# (bool)DataBinder.Eval(Container.DataItem,"IsGraduate") %>' runat="server"></asp:CheckBox> </ItemTemplate> </asp:TemplateColumn> <asp:TemplateColumn HeaderText="Skills"> <ItemTemplate> <asp:CheckBoxList id="CheckBoxList1" runat="server" > <asp:ListItem Value="C#" Selected="true">C#</asp:ListItem> <asp:ListItem Value="C++">C++</asp:ListItem> <asp:ListItem Value="VB">VB</asp:ListItem> <asp:ListItem Value="SQL Server" Selected="true">SQL Server</asp:ListItem> </asp:CheckBoxList> </ItemTemplate> </asp:TemplateColumn> <asp:TemplateColumn HeaderText="Experience"> <ItemTemplate> <asp:RadioButtonList id="RadioButtonList1" runat="server" > <asp:ListItem Value="1" Selected="true">Less then 1 Year</asp:ListItem> <asp:ListItem Value="3">Less then 3 Year</asp:ListItem> <asp:ListItem Value="5">Less then 5 Year</asp:ListItem> <asp:ListItem Value="10">Less then 10 Year</asp:ListItem> </asp:RadioButtonList> </ItemTemplate> </asp:TemplateColumn> <asp:TemplateColumn HeaderText="Degree"> <ItemTemplate> <asp:DropDownList id="DropDownList1" runat="server" > <asp:ListItem Value="HighSchool" >HighSchool</asp:ListItem> <asp:ListItem Value="Graduate" Selected="true">Graduate</asp:ListItem> <asp:ListItem Value="Masters">Masters</asp:ListItem> <asp:ListItem Value="PHD">PHD</asp:ListItem> </asp:DropDownList> </ItemTemplate> </asp:TemplateColumn> </Columns> </asp:DataGrid> <br /> <asp:Button id="GetValues" onclick="GetValues_Click" runat="server" Text="GetValues"></asp:Button> <br /> <asp:Label id="ResultField" runat="server"></asp:Label> </form> </body> </HTML>
