新的记录添加到Telerik的radgrid控件 [英] Add new record to Telerik RadGrid

问题描述

我有以下Telerik的radgrid控件，我使用C＃其中：

I have the following Telerik RadGrid, which I'm using in C#:

<MasterTableView Width="100%" EditMode= "InPlace" ClientDataKeyNames="menuID" CommandItemDisplay= "Top">
    <Columns>
        <telerik:GridBoundColumn DataField="Name" HeaderText="Name" SortExpression="Name" UniqueName="Name"></telerik:GridBoundColumn>
        <telerik:GridTemplateColumn UniqueName="Type" HeaderText="Type">
            <ItemTemplate>
                <asp:TextBox ID="Type" Text='<%# DataBinder.Eval(Container.DataItem, "Type") %>' runat="server"></asp:TextBox>
            </ItemTemplate>
            <EditItemTemplate>
            </EditItemTemplate>
        </telerik:GridTemplateColumn>
        <telerik:GridTemplateColumn UniqueName="List" HeaderText="List">
            <ItemTemplate>
                <asp:CheckBox ID="List" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "List") %>' />
            </ItemTemplate>
            <EditItemTemplate>
            </EditItemTemplate>
        </telerik:GridTemplateColumn>
        <telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
            <ItemTemplate>
                <asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
            </ItemTemplate>
            <EditItemTemplate>
            </EditItemTemplate>
        </telerik:GridTemplateColumn>
    </Columns>
</MasterTableView>

网格填充数据和编辑数据时正常工作。

The grid is populated with data, and working normally when editing the data.

但是当我点击Telerik的所提供的添加新记录按钮，然后一个空行，而不列中的任意文本框或复选框添加到编辑的新行补充说。这只是一个空行。我presume，我要在所谓的ItemDataBound事件动态创建的控件，但我没能找到实际的code这一点。

But when I click on the Add New Record button provided by Telerik, then an empty row is added without any TextBox or CheckBox in the columns to edit in the new Row added. It's just an empty row. I presume that I have to create the controls dynamically in the called ItemDataBound event, but I didn't manage to find the actual code for this.

我该如何解决这个问题？

How do I solve this?

推荐答案

请尝试以下code片段。

Please try with the below code snippet.

ASPX

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" OnNeedDataSource="RadGrid1_NeedDataSource"
    AllowFilteringByColumn="true" AllowPaging="true" OnItemCommand="RadGrid1_ItemCommand">
    <PagerStyle AlwaysVisible="true" />
    <MasterTableView DataKeyNames="UniqueID" CommandItemDisplay="Top">
        <Columns>
            <telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID">
            </telerik:GridBoundColumn>
            <telerik:GridTemplateColumn>
                <ItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("Name") %>'></asp:TextBox>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
<asp:Button ID="Button1" runat="server" Text="Save All" OnClick="Button1_Click" />

ASPX.CS

public partial class aaaa : System.Web.UI.Page
{

    public List<Employee> lstEmployee
    {
        get
        {
            if (Session["lstEmployee"] != null)
            {
                return (List<Employee>)Session["lstEmployee"];
            }
            else
            {
                return new List<Employee>();
            }
        }
        set
        {
            Session["lstEmployee"] = value;
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            List<Employee> list = new List<Employee>();

            Employee obj = new Employee();
            obj.ID = 1;
            obj.Name = "Name1";
            obj.UniqueID = Guid.NewGuid();
            list.Add(obj);

            obj = new Employee();
            obj.ID = 2;
            obj.Name = "Name2";
            obj.UniqueID = Guid.NewGuid();
            list.Add(obj);

            lstEmployee = list;
        }
    }

    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        RadGrid1.DataSource = lstEmployee;
    }

    protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.InitInsertCommandName)
        {
            saveAllData();
            lstEmployee.Insert(0, new Employee() { UniqueID = Guid.NewGuid() });
            e.Canceled = true;
            RadGrid1.Rebind();
        }
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        saveAllData();
    }

    protected void saveAllData()
    {
        //Update Session
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            Guid UniqueID = new Guid(item.GetDataKeyValue("UniqueID").ToString());
            Employee emp = lstEmployee.Where(i => i.UniqueID == UniqueID).First();
            emp.Name = (item.FindControl("TextBox1") as TextBox).Text;
        }
    }

}

public class Employee
{
    public Guid UniqueID { get; set; }
    public int ID { get; set; }
    public string Name { get; set; }
    public bool IsActive { get; set; }
    public int weeknumber { get; set; }
}
