我有一个包含复选框的gridviewC# 更改GridView中创建的行中复选框的属性,c#,asp.net,c#-4.0,gridview,C#,Asp.net,C# 4.0,Gridview,我有一个包含复选框的gridview <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCreated="GridView1_RowCreated" BackColor="#F1EFC5" CssClass="SearchEveryWhere_Table" Width="500px"> <HeaderStyle BackColor="#5391DD" Fore

</ItemTemplate>

<ItemStyle HorizontalAlign="Center" />

问题是当我想获取ID
时,我在chkStatus\u OnCheckedChanged
中获取chkStatus
:
rotected void chkStatus_OnCheckedChanged(object sender, EventArgs e)
{
try
{
CheckBox chk = sender as CheckBox;
string ID = chk.ID;
如何更改chkStatus
的ID
?如果我无法将该字符串保存在属性中,而该属性可以在chkStatus\u OnCheckedChanged
谢谢你更正了我的代码
在OnRowDatabound中添加
((CheckBox)e.Row.Cells[4].FindControl("chkStatus")).Attributes.Add("MyData", string.Format("{0}_{1}_{2}", CurrentREcord.CityCode, CurrentREcord.Page_Number, CurrentREcord.Switch.ToString());
在复选框选中/取消选中事件中,使用此选项获取数据
string data = chkStatus.Attributes["myData"];
您可以使用checkBox.Attributes.Add方法将值存储在自定义属性中,也可以在复选框附近插入HiddenField控件,并将所需的值存储在其value属性中(更好)。我不会接触ID属性,因为这是必需的(并在回发时重建)相反,我将使用复选框的属性。。查看此链接了解如何使用attibutes。以及如何在检查更改1时获取
chkStatus\u中的HiddenField
值?谢谢
string data = chkStatus.Attributes["myData"];
