Question

有谁知道如何将值从动态创建的gridview复选框传递到水晶报表？是否可能？我使用的是asp.net，vb.net和mssql。这是我的网格减去几个边界域：

<asp:gridview id="grid" runat="server" autogeneratecolumns="False" cellpadding="4"
    forecolor="#333333" gridlines="None" emptydatatext="No Products registered for this company...">
  <RowStyle BackColor="#EFF3FB" />
  <Columns>
    <asp:TemplateField HeaderText="Select">
      <ItemTemplate>
        <asp:CheckBox ID="chkSelect" runat="server" onclick="javascript:HighlightRow(this);" AutoPostBack="True"/>
      </ItemTemplate>
      <HeaderTemplate>
        <input id="chkAll" onclick="javascript:SelectAllCheckboxes(this);" runat="server" type="checkbox" />
      </HeaderTemplate>
    </asp:TemplateField>
    <asp:BoundField DataField="aid#" HeaderText="AID#" />
    <asp:BoundField DataField="brandname" HeaderText="Brand Name" />
    <asp:BoundField DataField="exp_date"  DataFormatString="{0:MM/dd/yyyy}" HeaderText="Exp. Date" />
  </Columns>
</asp:gridview>

这是在C＃中，但概念是相同的。你需要遍历每一行，找到复选框，检查它是否“已检查”并获取Datakeys值。

        // processCount is just used to calculate the total rows Checked.
        int processCount = 0;

        for (int indx = 0; indx < GridView1.Rows.Count; indx++)
        {
            Control control = GridView1.Rows[indx].FindControl("Id");

            if (control != null && control is CheckBox)
            {
                var chkbx = (CheckBox)control;
                if (chkbx.Checked)
                {
                    string rowId = GridView1.DataKeys[indx].Value.ToString();

                    //Do something with your DataKey value.....

                    processCount++;

                }
            }
        }
