推荐答案

您遇到什么错误?您要与该字段绑定的数据类型是什么?如果您是一个布尔值，并且希望将其绑定到CheckBox中，则无需这样做，因为GridView会自动处理所有这些问题.布尔值仅在CheckBox中呈现.
对于绑定任何其他值"，您可以在aspx页中或在后面的代码中使用该数据字段的绑定表达式.

What error are you getting ? What is the Data Type that you are binding with that field ? If you it''s a Boolean value and you want to bind it in CheckBox, there is no need, as GridView Automatically Takes care of all these. Boolean values renders in to CheckBox Only.
For Binding any other value, you can either use bind expression of that data field in aspx pages or in code Behind.

<asp:GridView ID="GridView1" runat="server">
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:checkbox id="CheckBoxid" runat="server" xmlns:asp="#unknown">
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView></asp:checkbox>

在RowDataBound期间，从后面的代码中，您可以按以下方式访问它

From the code behind, during RowDataBound, you can access it as below

protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
YourClass object = (YourClass)e.Row.DataItem;
CheckBox chkbox = e.Row.FindControl("CheckBoxid");
chkbox.Text = object.someProperties. 
}
}
