通过GridView的行循环和检查复选框控件 [英] Looping through GridView rows and Checking Checkbox Control

问题描述

目前，我有一个GridView从一个学生表显示的数据，这是我的电网和相关的SqlDataSource;

I currently have a GridView which displays data from a Student Table, here is my Grid and associated SQLDataSource;

                      <asp:GridView ID="GridView2" 
                        style="position:absolute; top: 232px; left: 311px;" 
                            AutoGenerateColumns="false" runat="server"
                        DataSourceID="SqlDataSource4">
                        <Columns>
                            <asp:TemplateField>
                            <ItemTemplate >
                            <asp:CheckBox runat="server" ID="AttendanceCheckBox" />
                            </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField>
                            <ItemTemplate>
                            <asp:Label ID="studentIDLabel" Text='<%# Eval("StudentID") %>' runat="server"></asp:Label>
                            </ItemTemplate>
                            </asp:TemplateField>                       
                            <asp:BoundField DataField="Name" HeaderText="Name" />
                        </Columns>
                     </asp:GridView>

                            的SelectCommand =SELECT [StudentID]，[名] FROM [学生] WHERE CourseID = @CourseID>结果
                            
                                
                            

" SelectCommand="SELECT [StudentID], [Name] FROM [Student] WHERE CourseID = @CourseID ">

我在页面上一个按钮，当用户点击该按钮，通过我在GridView的每一行需要循环，然后找到复选框，然后我需要检查，如果该复选框被选中。如果复选框被选中，我需要在标签模板字段添加值到不同的数据库中的表。
我使用C＃code。
任何帮助深表AP preciated，先谢谢了！

I have a button on the page which when the user clicks the button I need to loop through each row in the GridView, then find the CheckBox then I need to check if the checkbox is checked or not. If the checkbox is checked I need to add the value in the Label Template Field to a different table in the database. I am using C# Code. Any help is much appreciated, thanks in advance!

推荐答案

循环像

foreach (GridViewRow row in grid.Rows)
{
   if (((CheckBox)row.FindControl("chkboxid")).Checked)
   {
    //read the label            
   }            
}
