如何添加DataGrid组合框列 [英] how to add a DataGrid Combo Box Column

问题描述

朋友，

从最近两天开始，我搜索了整个网络.但我没有得到任何有用的代码
关于一个DataGrid ComboBoxcolumn；我有一个带有4列的DataGrid，位置"
从"，到"和调度状态".这些列绑定到MSAccess数据库，但是我希望将第4列作为ComboBoxColumn，以便它给出一些预先确定的值，例如combobox列中的"Dispatched"，"Received"，"ReturnedBack"，"waiting for delivery".

问候

代替绑定字段"，对组合框"列使用模板字段"

In stead of Bound Field use Template Field for the Combob box column

<asp:TemplateField HeaderText="Example">
 <ItemTemplate>
                                                                <asp:DropDownList ID="ddExample"  AutoPostBack="false" runat="server" />
</ItemTemplate>
                                                            </asp:TemplateField>



and in .cs file write the function to get values need to listed on Drop Down 

and on gdv_RowDatabound event bind it with gridview

like this

<pre lang="c#"><pre>DropDownList ddexample = (DropDownList)e.Row.FindControl("ddExample");
                    ddexample .DataSource = options;
          ddexample .DataTextField =options.Columns["Examples"].ToString();
          ddexample .DataValueField = options.Columns["Examples"].ToString();
                    
                    ddexample .DataBind();
                    TableCell gridview= e.Row.Cells[10];
                    ddexample .SelectedValue = ddexample .Text;
