解决方案
我想你根据您code以下的例如
此演示使用自动插入它处理控件的值会自动以及使用数据源插入到数据库中。在你的情况下，你想通过code访问控制。
我不得不简化code跨越我的观点。这应该得到你所需要的。
C＃的
保护无效RadGrid1_InsertCommand（对象源，GridCommandEventArgs E）
{
VAR的DataItem = e.Item为GridDataItem;
变种的textBox = dataItem.findControl（txtSubcomName）作为RadTextBox;
// ...得到这样的控件的其余部分
textBox2.Text = textBox.Text;
}
ASP.net 的
＆LT; Telerik的：radgrid控件ID =RadGrid1=服务器
OnInsertCommand =RadGrid1_InsertCommand＆GT;
＆LT; MasterTableView的DataKeyNames =ID＆GT;
＆LT;柱体和GT;
＆LT; Telerik的：GridButtonColumn UniqueName =InsertColumn按钮类型=的ImageButton的CommandName =插入＆GT;

解决方案
I take it you based your code on the following example
This demo is using automatic inserts which handles the value of the controls automatically as well as uses the datasource to insert into the database. In you case you want access to the controls through code.
I had to simplify the code to get my point across. This should get what you need
C#
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;
}
ASP.net
<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
