Question

我有一个嵌套网格我想在另一个表格中存在datakey时检查网格中的列

网格就像这样

<asp:GridView Width="100%" DataKeyNames="PK_ServiceTypeID" HorizontalAlign="Center" runat="server" OnRowDataBound="gridServiceLocations_RowDataBound" AutoGenerateColumns="false" ID="gridServiceLocations" BackColor="White" BorderColor="#3366CC" BorderStyle="None" BorderWidth="1px" CellPadding="4">
 <Columns>
  <asp:TemplateField>
  <ItemTemplate>
  <asp:CheckBox runat="server" />
   </ItemTemplate>
   </asp:TemplateField>
   <asp:TemplateField>
  <ItemTemplate>
   <img alt="" style="cursor: pointer" src="../../Images/plus.png" />
    <asp:Panel ID="pnlOrders" runat="server" Style="display: none">
    <asp:GridView ID="gvOrders" runat="server" AutoGenerateColumns="false" Width="100%" DataKeyNames="PK_ServiceDetailID">
   <Columns>
   <asp:TemplateField>
   <ItemTemplate>
   <asp:CheckBox runat="server" />
   </ItemTemplate>
   </asp:TemplateField>
    <asp:BoundField DataField="Service" HeaderText="Service" />
    </Columns>
   </asp:GridView>
   </asp:Panel>
    </ItemTemplate>
 </asp:TemplateField>
 <asp:BoundField DataField="ServiceTypeName" HeaderText="ServiceTypeName" HeaderStyle-HorizontalAlign="Center" />
     </Columns>
     </asp:GridView>

我已经从后面的代码绑定了这个网格

如果我理解，我认为类似的东西会起作用：

首先，您需要使用明确的数据：从您的sql列获取值并将其存储到字符串（或任何您想要的类型）数组或List中，如下所示：

       //Get your column value from your db
        string myValueFromDb = "0000000062,0000000034,0000000016,0000000174,0000000055";
        //Split the values into an list of string
        myValues = new List<string>(myValueFromDb.Split(','));

       //Here you have all your db values stored in the list myValues

但要访问您的复选框，您必须添加ID。喜欢：asp:CheckBox runat="server" ID="checkBox" />

现在，您需要检查gridview的每一行。这样的事情：

protected void gridServiceLocations_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowIndex != -1)
        {

            //Get the value of the current row DataKey
           string dataKey = grid_view.DataKeys[e.Row.RowIndex].Value.ToString();

            //GET THE ROW
            GridViewRow row = e.Row;

            //Now compare it with your value
            if (myValues.Contains(dataKey))
            {
                //CHECK CASE
                //The index of column of the column where the checkbox are (1 here, change it )
                CheckBox checkbox = ((CheckBox)row.Cells[1].FindControl("checkBox"));
                checkbox.Checked = true;

            }
            else
            {
                //UNCHECK CASE
                CheckBox checkbox = ((CheckBox)row.Cells[1].FindControl("checkBox"));
                checkbox.Checked = false;

            }                
        }
    }

Gridview ItemTemplate复选框，基于Sql Numeric Feild进行检查
