推荐答案

首先，您必须动态创建一个下拉列表并将其添加到gridview编辑临时字段中在gridview行中创建的事件

然后在行命令事件中找到像
这样的dropdownlis控件

First you have to create a dropdown list dynamically and add it to gridview edit tempalte field in gridview row created event

then on row command event find that dropdownlis control like

If e.CommandName = "Edit" Then
          Dim i As Integer = e.CommandArgument
          Dim row As GridViewRow = GridView2.Rows(i)

                  Dim dd As DropDownList       
   dd= DirectCast(row.FindControl("ddl1"), DropDownList)
           

      End If

尝试此操作，首先获取一个模板字段，然后添加项目模板，然后在编辑模板内部将下拉列表如下...

try this ,first take a template field then add item template,then inside edit template put the dropdown as follow...

<asp:templatefield headertext="Status" sortexpression="with_status" xmlns:asp="#unknown">
                    <itemtemplate>
                        <asp:label id="Label1" runat="server" text="<%# Bind("with_status") %>"></asp:label>
                    </itemtemplate>

                    <edititemtemplate>
                        <asp:dropdownlist id="DropDownList1" runat="server">
                        <asp:listitem value="0">-Select- </asp:listitem>
                        <asp:listitem value="1">pending </asp:listitem>
                      <asp:listitem value="2">completed </asp:listitem>

                        </asp:dropdownlist>
                    </edititemtemplate>
                </asp:templatefield>

aspx.cs

在rowupdating上输入以下代码

aspx.cs

on rowupdating put the following code

DropDownList ddl2 = (DropDownList)GridView1.Rows[e.RowIndex].FindControl("DropDownList1");
            if (ddl2.SelectedValue.ToString() != "0")
            {
                SqlDataSource1.UpdateParameters["with_status"].DefaultValue = ddl2.SelectedItem.ToString();
 
            }
