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：
<%@PageLanguage="C#"%>
<%@importNamespace="System.Collections"%>
<scriptrunat="server">
voidPage_Load(Objectsender,EventArgse){
if(!Page.IsPostBack){
ArrayListdata=newArrayList();
data.Add(newPerson("Tom",33,true));
data.Add(newPerson("Jhon",39,false));
data.Add(newPerson("Mark",20,false));
data.Add(newPerson("Linda",27,true));
MyDataGrid.DataSource=data;
MyDataGrid.DataBind();
}
}
voidGetValues_Click(Objectsender,EventArgse){
StringResult="";
foreach(DataGridItemdataGridIteminMyDataGrid.Items){
//Getnamefromcell[0]
StringName=dataGridItem.Cells[0].Text;
//Gettextfromtextboxincell[1]
StringAge=((TextBox)dataGridItem.FindControl("AgeField")).Text;
//GetCheckedpropertyofCheckboxcontrol
boolIsGraduate=((CheckBox)dataGridItem.FindControl("IsGraduateField")).Checked;
//getValuesfromCheckboxlist
StringSkills="";
foreach(ListItemitemin((CheckBoxList)dataGridItem.FindControl("CheckBoxList1")).Items){
if(item.Selected){
Skills+=item.Value+",";
}
}
Skills=Skills.TrimEnd(',');
//GetRadioButtonListSelectedtext
StringExperience=((RadioButtonList)dataGridItem.FindControl("RadioButtonList1")).SelectedItem.Text;
//GetDropDownListSelectedtext
StringDegree=((DropDownList)dataGridItem.FindControl("DropDownList1")).SelectedItem.Text;
//BuildStringtoshowresult.
Result+=Name;
Result+="[Age-"+Age+"]";
if(IsGraduate){
Result+="IsGraduate,";
}else{
Result+="IsnotGraduate,";
}
Result+="HasSkills["+Skills+"],";
Result+="Has"+Experience+"Experience,And";
Result+="Has"+Degree+"Degree.";
Result+="<br>";
}
ResultField.Text=Result;
}
classPerson{
String_Name;
int_Age;
bool_IsGraduate;
publicPerson(Stringname,intage,boolisGraduate){
_Name=name;
_Age=age;
_IsGraduate=isGraduate;
}
publicStringName{
get{return_Name;}
}
publicintAge{
get{return_Age;}
}
publicboolIsGraduate{
get{return_IsGraduate;}
}
}
