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"); }
