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 btnCal_Click(object sender, EventArgs e){foreach (RepeaterItem item in rpdList.Items){if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem){HiddenField hfkey = item.FindControl("hfkey") as HiddenField;TextBox txtUPSShipQty = item.FindControl("txtUPSShipQty") as TextBox;DataRow[] rows = dt.Select("ID ='" + hfkey.Value + "'");if (rows != null && rows.Length > 0){if (rows[0]["UPSShipQty"].ToString().Trim() != txtUPSShipQty.Text.Trim()){rows[0]["UPSShipQty"] = txtUPSShipQty.Text.Trim();CalFBAShipQty2(dt, 3, "UPSShipQty", hfkey.Value.Trim());break;}}}}rpdList.DataSource = dt;rpdList.DataBind();}

2.让TextBox 触发Repeater 的ItemCommand事件，同样需要绑定TextChanged 并设置AutoPostBack ="true"，然后在TextChanged事件中调用ItemCommand

HTML

<asp:Repeater ID="Repeater1" runat="server" onitemcommand="Repeater1_ItemCommand">
<ItemTemplate>
<%#Eval("txt") %><table><tr><td><asp:TextBox ID="TextBox1" runat="server" AutoPostBack="true" OnTextChanged="TextBox1_TextChanged"></asp:TextBox></td><td><asp:Button ID="Button1" runat="server" Text="Button"  /></td><td><asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true"/></td></tr></table>
</ItemTemplate>
</asp:Repeater>

后台代码

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");
}
