Repeater 中TextBox 触发TextChanged事件

两种方法

1.TextBox 绑定TextChanged 并设置AutoPostBack ="true" ，如果不设置AutoPostBack ="true"则不会触发TextChanged事件，然后在对应的方法里面循环Repeater查找改变项

部分代码

<ItemTemplate >
<tr>
<td style ="width :9%;"><%#Eval("Date")%> <asp:HiddenField ID ="hfkey" runat ="server" Value ='<%#Eval("ID")%> ' /></td>
<td style ="width :9%;"><%#Eval("FBASalesDays")%></td>
<td style ="width :9%;"><asp:TextBox ID ="txtUPSShipQty"  runat="server" Text ='<%#Eval("UPSShipQty")%>' AutoPostBack ="true"   OnTextChanged ="btnCal_Click" ></asp:TextBox> </td>
</tr>
</ItemTemplate>

后台部分代码

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.Add("id");
dt.Columns.Add("txt");
dt.Rows.Add("1", "1txt");
dt.Rows.Add("2", "2txt");
Repeater1.DataSource = dt;
Repeater1.DataBind();
}
}
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
//注意这里的参数设置
RepeaterCommandEventArgs e1 = new RepeaterCommandEventArgs(((TextBox)sender).NamingContainer as RepeaterItem,sender,new CommandEventArgs("test",null));
Repeater1_ItemCommand(Repeater1, e1);
}
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
string ss = e.CommandName;
if (ss == "test")
Response.Write("123");
}
