Question

我在EditItemTemplate中有一个带有复选框的RadGrid，用于处于活动或非活动状态。

此复选框仅显示项目何时更新或添加为新项目。我有一个ControlParameter用于复选框，但由于它是列表中的许多复选框的递归，它会抛出旧的“无法在ControlParameter中找到控件'cbActive'错误。

除了页面加载上的Radgrid绑定之外，我没有任何真正的CS代码。

ASPX代码：

<telerik:RadGrid ID="RadGrid1" runat="server" Skin="Vista" Width="500px"
    GridLines="None" AllowFilteringByColumn="False" AllowSorting="True" OnExportCellFormatting="RadGrid1_ExportCellFormatting"
     AllowAutomaticInserts="True"  AllowAutomaticDeletes="true" AllowAutomaticUpdates="True" AutoGenerateEditColumn="True"  AutoGenerateDeleteColumn="true">
    <MasterTableView AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="SqlDataSource1" ItemStyle-HorizontalAlign="Left" CommandItemDisplay="TopAndBottom">
        <Columns>
            <telerik:GridBoundColumn DataField="ID" HeaderText="ID" SortExpression="ID"
                    UniqueName="ID" Visible="False" ReadOnly="true">
                </telerik:GridBoundColumn>
            <telerik:GridTemplateColumn HeaderText="Active" SortExpression="Active" UniqueName="Active" ItemStyle-Width="100" Visible="false">
                <EditItemTemplate>
                    <asp:CheckBox ID="cbActive" runat="server" Checked='<%# GenerateBindString(Container.DataItem) %>' />
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
         </Columns>
    </MasterTableView>
</telerik:RadGrid>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:LBCust %>" 
    SelectCommand="SELECT * FROM [LBX_Portal_AccountNumbers] WHERE ([Site] = @Site) AND (Active=@Active OR @Active = '0') ORDER BY AccountNumber"
    DeleteCommand="DELETE FROM [LBX_Portal_AccountNumbers] WHERE [ID] = @ID" 
    InsertCommand="INSERT INTO [LBX_Portal_AccountNumbers] ([AccountNumber], [Site], [Active]) VALUES (@AccountNumber, @Site, @Active)" 
    UpdateCommand="UPDATE [LBX_Portal_AccountNumbers] SET [AccountNumber] = @AccountNumber,  [Active] = @Active WHERE [ID] = @ID">
    <SelectParameters>
        <asp:ControlParameter ControlID="dd_Status" Name="Active" 
            PropertyName="SelectedValue" Type="String" />
    </SelectParameters>
    <DeleteParameters>
        <asp:Parameter Name="ID" Type="Int32" />
    </DeleteParameters>
    <InsertParameters>
        <asp:Parameter Name="AccountNumber" Type="String" />
        <asp:Parameter Name="Site" Type="String" />
        <asp:ControlParameter ControlID="cbActive" 
            PropertyName="Checked" Type="Boolean" />
    </InsertParameters>
    <UpdateParameters>
        <asp:Parameter Name="AccountNumber" Type="String" />
        <asp:ControlParameter ControlID="cbActive" 
            PropertyName="Checked" Type="Boolean" />
    </UpdateParameters>
</asp:SqlDataSource>

Answer 1

您无法通过控制参数设置值;你可以做的是使用<asp:Parameter>代替，并通过以下方法在参数上设置DefaultValue属性：

sqlDataSource1.SelectParameters[0].DefaultValue = "X"

或者，对于网格，我知道GridView它有一组值，用于执行更新;您可以添加一个表示复选框控件的条目，该条目将被推送到数据源中。我知道RadGrid是否有相同的选项。

所以它花了很多时间环顾四周，但我无法通过CS点击命令来做到这一点。这是我的新代码：

<telerik:RadGrid ID="RadGrid1" runat="server" Skin="Vista" Width="500px"
    GridLines="None" AllowFilteringByColumn="False" AllowSorting="True" OnExportCellFormatting="RadGrid1_ExportCellFormatting"
     AllowAutomaticInserts="True"  AllowAutomaticDeletes="true" AllowAutomaticUpdates="True" AutoGenerateEditColumn="True"  AutoGenerateDeleteColumn="true" OnItemCommand="RadGrid1_ItemCommand">
    <MasterTableView AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="SqlDataSource1" ItemStyle-HorizontalAlign="Left" CommandItemDisplay="TopAndBottom">
        <Columns>
            <telerik:GridTemplateColumn HeaderText="ID" SortExpression="ID" UniqueName="ID" Visible="false" ReadOnly="true"> 
                <ItemTemplate> 
                    <asp:Label ID="lblIDView" runat="server" Text='<%# Bind("ID") %>'></asp:Label> 
                </ItemTemplate> 
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="ID" SortExpression="IDEdit" UniqueName="IDEdit" Visible="false">
                <ItemTemplate />
                <EditItemTemplate>
                    <asp:Label ID="lblID" runat="server" Text='<%# Bind("ID") %>'></asp:Label> 
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridBoundColumn DataField="AccountNumber" HeaderText="Sapphire Account Number"

            <telerik:GridTemplateColumn HeaderText="Account Number" SortExpression="AccountNumber" UniqueName="AccountNumber" Visible="false">
                <ItemTemplate />
                <EditItemTemplate>
                    <asp:Textbox ID="txtAccountNumber" runat="server" Text='<%# Bind("AccountNumber") %>' />
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="Active" SortExpression="Active" UniqueName="Active" ItemStyle-Width="100" Visible="false">

                <EditItemTemplate>
                    <asp:CheckBox ID="cbActive" runat="server" Checked='<%# GenerateBindString(Container.DataItem) %>' />
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn HeaderText="Status" SortExpression="Active" UniqueName="Active" ItemStyle-Width="100">

         </Columns>

</telerik:RadGrid>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:LBCust %>"

    DeleteCommand="DELETE FROM [LBX_Portal_AccountNumbers] WHERE [ID] = @ID" 
    InsertCommand="INSERT INTO [LBX_Portal_AccountNumbers] ([AccountNumber], [Site], [Active]) VALUES (@AccountNumber, @Site, @Active)" 
    UpdateCommand="UPDATE [LBX_Portal_AccountNumbers] SET [AccountNumber] = @AccountNumber,  [Active] = @Active WHERE [ID] = @ID">

CS CODE：

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == "PerformInsert")
    {

        GridEditFormItem gridEditFormItem = (GridEditFormItem)e.Item;

        Label lblID = (Label)gridEditFormItem.FindControl("lblID");
        TextBox txtAccountNumber = (TextBox)gridEditFormItem.FindControl("txtAccountNumber");
        CheckBox cbActive = (CheckBox)gridEditFormItem.FindControl("cbActive");

        bool isActive = false;

        if (cbActive.Checked)
            isActive = true;
        else
            isActive = false;

        string SqlStr = "INSERT INTO [LBX_Portal_AccountNumbers] ([AccountNumber], [Site], [Active])";
        SqlStr += " VALUES ('" + txtAccountNumber.Text + "'" + ", '" + SiteName + "'" + ", '" + isActive + "')";

        SqlDataSource1.InsertCommand = SqlStr;
        SqlDataSource1.Insert();
    }


    if (e.CommandName == "Update")
    {

        GridEditFormItem gridEditFormItem = (GridEditFormItem)e.Item;

        Label lblID = (Label)gridEditFormItem.FindControl("lblID");
        TextBox txtAccountNumber = (TextBox)gridEditFormItem.FindControl("txtAccountNumber");
        CheckBox cbActive = (CheckBox)gridEditFormItem.FindControl("cbActive");

        bool isActive = false;

        if (cbActive.Checked)
            isActive = true;
        else
            isActive = false;

        string SqlStr = "UPDATE [LBX_Portal_AccountNumbers] SET [AccountNumber] = '" + txtAccountNumber.Text;
        SqlStr += "', [Active] = '" + isActive + "'  WHERE [ID] = " + lblID.Text;

        SqlDataSource1.UpdateCommand = SqlStr;
        SqlDataSource1.Update();
    }
}

用于插入和更新的EditItemTemplate列中的RadGrid（Gridview）递归复选框
