解决方案

循环与GridView的行

查找CheckBox控件

检查其Checked属性为true

如果有，调用插入语句

设置你想从形象和DropDownList中得到的值。当然，你需要太上使用的FindControl。

 昏暗cbSelect作为复选框，imgToInsert作为图像，ddlStatus作为的DropDownList
对于每一个R作为GridViewRow在gvDetails.Rows
    cbSelect = r.Cells（0）.FindControl（CheckBox2）    如果cbSelect.Checked然后
        imgToInsert = r.Cells（1）.FindControl（IMG preVIEW）
        ddlStatus = r.Cells（2）.FindControl（dpdListEstatus）        Insert语句放在这里...

I have a gridview which contains images (populated dynamically from database) and dropdownlist which contains two values. First column contains checkbox. I want to insert selected checkbox's images and dropdown values to a new table on button click. What may be the suitable way? Here is the grid view:

<asp:GridView ID="gvDetails" runat="server" AutoGenerateColumns="false" AllowPaging="true" 
            EmptyDataText="No images found" OnPageIndexChanging="gvDetails_PageIndexChanging" PageSize="5">
            <Columns>

                <asp:TemplateField>
                    <HeaderTemplate>
                        <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true" OnCheckedChanged="CheckUncheckAll"/>
                    </HeaderTemplate>
                    <ItemTemplate>
                        <asp:CheckBox ID ="CheckBox2" runat="server" />
                    </ItemTemplate>
                </asp:TemplateField>

                <asp:TemplateField HeaderText="Image">                   
                    <ItemTemplate>
                        <asp:Image ID="imgPreview" ImageUrl='<%#
                        "ImageHandler.ashx?imgID="+ Eval("ID") %>' runat="server"
                            Height="80px" Width="80px" />
                    </ItemTemplate>
                </asp:TemplateField>

                <asp:TemplateField HeaderText="Dropdown" ItemStyle-Width="50px">
                    <ItemTemplate>
                        <asp:DropDownList ID="dpdListEstatus" runat="server" OnSelectedIndexChanged="dpdListEstatus_SelectedIndexChanged" AutoPostBack="true">
                            <asp:ListItem>A</asp:ListItem>
                            <asp:ListItem>B</asp:ListItem>
                        </asp:DropDownList>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />

解决方案

Loop with gridview rows

Find for the checkbox control

Check if its Checked property is true

If yes, call insert statement

Set the values you want to get from image and dropdownlist. Of course you need to use findcontrol on it too.

Dim cbSelect As CheckBox, imgToInsert As Image, ddlStatus As DropDownList
For Each r As GridViewRow In gvDetails.Rows
    cbSelect = r.Cells(0).FindControl("CheckBox2")

    If cbSelect.Checked Then
        imgToInsert = r.Cells(1).FindControl("imgPreview")
        ddlStatus = r.Cells(2).FindControl("dpdListEstatus")

        'Insert statement goes here...
    End If
Next r
