Ajax in UserControl
(1 answer)
Closed 8 years ago.
I am using CalenderExtender in my project inside in content place holder and calender extender is in a UserControl. This control is working in normal aspx-page but when i am dragging this control in ContentPlaceHolder then it is not working. Actually the Calender is not appearing in textBox below is my code which i used in my project.
ASPX:
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="Calender1.ascx.cs" Inherits="Facultymanagement.Calender1" %>
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<asp:TextBox ID="txtcalender" runat="server">
</asp:TextBox>
<asp:CalendarExtender ID="CalendarExtender1" runat="server" Format="MM/dd/yyyy"
TargetControlID="txtcalender" PopupButtonID="txtcalender"></asp:CalendarExtender>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
Codebehind:
protected void Page_Load(object sender, EventArgs e)
{
if (CalendarExtender1.SelectedDate.ToString() != "")
{
txtcalender.Text = CalendarExtender1.SelectedDate.ToString();
}
}
public string TextBox1Value
{
get
{
return txtcalender.Text;
// return Convert.ToString(Calendar.SelectedDate);
}
set { txtcalender.Text = value; }
}
}
This is the place where i am trying to access the value:
protected void Button1_Click1(object sender, EventArgs e)
{
Label1.Text = calender1.TextBox1Value.ToString();
}
You need to find control first
ContentPlaceHolder mpContentPlaceHolder1 = (ContentPlaceHolder)Master.FindControl("ContentPlacename");
if (mpContentPlaceHolder1 != null)
{
Button btn_searsh;
btn_searsh = (Button)mpContentPlaceHolder1.FindControl("main_search");
btn_searsh.CssClass += " " + "btn-primary";//to pass the rentpage class
}
I think you must doo something wrong.
The following code works:
WebUserControl1.ascx:
<%# Control Language="C#" ClassName="WebUserControl" %>
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<script runat="server">
</script>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Image ID="Image1" runat="server" />
<cc1:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="TextBox1" PopupButtonID="Image1">
</cc1:CalendarExtender>
Default.aspx:
<%# Page Language="C#" %>
<%# Register Src="WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Why is GridView1_SelectedIndexChanged not working?
I'm learning ASP.NET on my own (which means I learn through youtube), using VS 2015.
I created a grid of items and want to show the selected item in a textbox, but code doesn't do any change.
I created an empty project, added a masterpage and default page, and just added a text and grid, scriptmanager updatepanel contenttemplate.
Whenever I click select on any row from the grid textbox is still empty.
MasterPage.master:
<%# Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
Default.aspx:
<%# Page Title="" enableeventvalidation="true" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<style type="text/css">
.auto-style1 {
width: 100%;
}
</style>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<table class="auto-style1">
<tr>
<td>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
<tr>
<td>
<asp:GridView ID="GridView1" runat="server" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
<Columns>
<asp:CommandField ButtonType="Button" ShowSelectButton="True" />
</Columns>
</asp:GridView>
</td>
</tr>
</table>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>
Default.aspx.cs:
using System;
using System.Data;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable tbl = new DataTable();
tbl.Columns.Add("serial");
for (int i = 0; i < 4; i++)
{
DataRow row = tbl.NewRow();
row[0] = i + 1;
tbl.Rows.Add(row);
}
GridView1.DataSource = tbl;
GridView1.DataBind();
}
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
TextBox1.Text = GridView1.SelectedRow.Cells[0].Text;
}
}
You are selecting the wrong cell on the SelectedIndexChanged method.
The first Cell (index 0) contains the button, so you want the second cell (index 1).
You should place a breakpoint on the method and see for yourself what other properties are filled in the GridView.

...
<asp:Panel ID="pnlBody" runat="server">
<fieldset class="grid-form">

</div>
</fieldset>
...
<script type="text/javascript">
$(document).ready(function () {
$("#<%= ddlState.ClientID %>").select2();
});
</script>
</asp:Panel>

<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

function SetButtonStatus(sender, target) {
var first = document.getElementById('<%=txtfirst.ClientID %>');
var second = document.getElementById('<%=txtText.ClientID %>');
//Condition to check whether user enters text in two textboxes or not
if ((sender.value.length >= 1 && first.value.length >= 1) && (sender.value.length >= 1 && second.value.length >= 1))
document.getElementById(target).disabled = false;
else
document.getElementById(target).disabled = true;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="txtfirst" runat="server" onkeyup="SetButtonStatus(this,'btnButton')"></asp:TextBox>
<asp:TextBox ID="txtText" runat="server" onkeyup="SetButtonStatus(this,'btnButton')"></asp:TextBox>
<asp:Button ID="btnButton" runat="server" Text="Button" Enabled="false" />
</div>
</form>
</body>
</html>
its runnung perfect and javascript work fine,
but when i am using this javascript code in another page like
<%# Page Title="About Us" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeFile="About.aspx.cs" Inherits="About" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<script language="javascript" type="text/javascript">
function SetButtonStatus(sender, target) {
var first = document.getElementById('<%=txtfirst.ClientID %>');
var second = document.getElementById('<%=txtText.ClientID %>');
//Condition to check whether user enters text in two textboxes or not
if ((sender.value.length >= 1 && first.value.length >= 1) && (sender.value.length >= 1 && second.value.length >= 1))
document.getElementById(target).disabled = false;
else
document.getElementById(target).disabled = true;
}
</script>
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<asp:TextBox ID="txtfirst" runat="server" onkeyup="SetButtonStatus(this,'btnButton')"></asp:TextBox>
<asp:TextBox ID="txtText" runat="server" onkeyup="SetButtonStatus(this,'btnButton')"></asp:TextBox>
<asp:Button ID="btnButton" runat="server" Text="Button" Enabled="false"/>
</asp:Content>
javascript not working and no error issue.
i am using visual studio 2010
asp.net c#.
Try to pass actual ID of button you get after rendering the page. (you can copy from view source)
<asp:TextBox ID="txtfirst" runat="server" onkeyup="SetButtonStatus(this,'ContentPlaceHolder1_btnButton')"></asp:TextBox>
<asp:TextBox ID="txtText" runat="server" onkeyup="SetButtonStatus(this,'ContentPlaceHolder1_btnButton')"></asp:TextBox>
it will work.
Thanks
I already read Stack Overflow question How to bind a List to a gridview?.
But I need to bind a List<DateTime> to a gridview, but MAINLY I also want be able to access the DateTime value from within a ItemTemplate. How do I do that? When I was working with a DataTable, I used to do it like that:
<%# Eval("SDIndex") %>
How would I do it linking it directly to the List<DateTime>?
You may try the following:
<%# Page Language="C#" %>
<%# Import Namespace="System.Linq" %>
<script type="text/C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
var dates = Enumerable.Range(1, 20).Select(x => new DateTime(2011, 4, x)).ToList();
grd.DataSource = dates;
grd.DataBind();
}
</script>

This should also work:
<%# string.Format("{0:dd/MM/yyyy}", GetDataItem()) %>
