Question

先生/女士，

我将通过单击Add来显示插入命令以将RadTextbox显示为InsertItem模板，并在输入RadGrid内的所有数据后单击Add New Record

但是当它进入测试时，发现无法完成获取项目并始终显示为空

以下是我的代码，请回答

     protected void btnAddRecord_grdFlex_performInsert(object sender, EventArgs e)
    {
        RadButton butt = sender as RadButton;

        foreach (GridDataItem dataItem in grdFlex.MasterTableView.Items)
        {

            RadTextBox textBox1 = (RadTextBox)(dataItem["Company"].FindControl("txtSubcomName"));
            RadTextBox textBox2 = (RadTextBox)(dataItem["FlexAcctCode"].FindControl("txtFlex"));
            RadComboBox ab= (RadComboBox)(dataItem["Company"].FindControl("cboCompany"));
            RadComboBox cd= (RadComboBox)(dataItem["FlexAcctCode"].FindControl("cboFlexAcctCode"));


            if (!String.IsNullOrEmpty(textBox1.Text))
            {
                ab.Items.Insert(1, new RadComboBoxItem(textBox1.Text));
                ab.SelectedIndex = 0;
                textBox1.Text = String.Empty;
            }

            if (!String.IsNullOrEmpty(textBox2.Text))
            {
                cd.Items.Insert(1, new RadComboBoxItem(textBox2.Text));
                cd.SelectedIndex = 0;
                textBox2.Text = String.Empty;
            }
        }
    }

我根据以下example

将您的代码视为基础

此演示使用自动插入，自动处理控件的值，并使用数据源插入数据库。在您的情况下，您希望通过代码访问控件。

我必须简化代码以获得我的观点。这应该得到你需要的东西

的 C＃ 的

protected void RadGrid1_InsertCommand(object source, GridCommandEventArgs e) { var dataItem = e.Item as GridDataItem; var textBox = dataItem.findControl("txtSubcomName") as RadTextBox; //... get the rest of the controls like this textBox2.Text = textBox.Text; }

的 ASP.net 的

<telerik:RadGrid ID="RadGrid1" runat="server" OnInsertCommand="RadGrid1_InsertCommand"> <MasterTableView DataKeyNames="ID"> <Columns> <telerik:GridButtonColumn UniqueName="InsertColumn" ButtonType="ImageButton" CommandName="Insert"> </telerik:GridButtonColumn> <telerik:GridTemplateColumn UniqueName="Company" HeaderText="Company"> <InsertItemTemplate> <telerik:RadTextBox ID="txtSubcomName" runat="server" ></telerik:RadTextBox> </InsertItemTemplate> <ItemTemplate> <telerik:RadComboBox ID="cboCompany" runat="server" Filter="Contains" AppendDataBoundItems="true" AllowCustomText="True" Width="100%" SelectedValue='<%# Bind("Company") %>'> <Items> <telerik:RadComboBoxItem Text="Yau Lee Construction Co. Ltd" Value="YLC" /> <telerik:RadComboBoxItem Text="Yau Lee Holdings" Value="YLH" /> </Items> </telerik:RadComboBox> </ItemTemplate> <ItemStyle Width="200px" /> </telerik:GridTemplateColumn> ... rest of grid
