IIF return a ressource variable - c#

Here's the ligne :
<%# IIf(Container.DataItem("OldAdress") = Container.DataItem("NewAdress"), "", "Adress")%>
Instead of hard coding "Adress", I want to return a resource variable. Is it possible ?


By using the GetGlobalResourceObject / GetLocalResource object functions. From

Image1.Visible = true;

label.visible = true not working

The visible function doesnt work, but why? Is a true set in a callback not allowed?. When I set the visible to true on top of the page(_Default : System.Web.UI.Page) it is working.
information_remedyID.Visible = true;
information_remedyID.Text = inquiryId;
TOP Class:
public partial class _Default : System.Web.UI.Page
{
.......
private static string inquiryId;
......
private void InsertIncidentCallback(server3.ILTISAPI api, IAsyncResult result, string username, string msg_id)
{
string message;
api.EndInsertIncident(result, out message);
if (message == null)
{
string responseXML;
api.REMEDY_ReadResponseXML(username, out responseXML, out msg_id);
XDocument doc = XDocument.Parse(responseXML);
inquiryId = (string)doc.Root.Element("inquiry_id");

{
information_text.Text = "....";

{
information_remedyID.Visible = true;
information_remedyID.Text = inquiryId;

Do you use a UpdatePanel with UpdateMode="Conditional"
<asp:UpdatePanel ID="ProfileEditingUpdatePanel" runat="server" UpdateMode="Conditional">
In case you use WPF
information_remedyID.Visibility = Visibility.Visible;
Sorry, overread ASP!

if (inquiryId == null | inquiryId == "")
If this should be an or change it to a double stripe:
if (inquiryId == null || inquiryId == "")

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

<form id="form1" runat="server">

<asp:Button ID="requestbt" runat="server" OnClick="Button1_Click" Text="Software zuweisen" /><br />
<asp:Label ID="information_text" runat="server" Text="information_text" Visible="False"></asp:Label><br />

<br />
</ContentTemplate>
</asp:UpdatePanel>
</form>
</body>
</html>
And in your code, after you changed the visibility:
MyUpdatePanel.Update();

I couldn't get this to work either.
A workaround is to use Style="display: none;" instead of Visible="False". Then you can reveal it with
information_remedyID.Style["display"] = "initial";

Whenever I click button I want label text to be "Modified by click event" but it remains same "On Load". Can someone please help

Try adding a trigger in your update panel as shown:
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
</Triggers>
And Check ScriptManager's EnablePartialRendering and remove it if it presented or set it to true

you can add a method using C# to trigger the event.
double-click button to create a button click event.
add a code to change the label text to "Modified by click event"
for example,
protected void Button1_Click(object sender, EventArgs e)｛
Label1.text = "Modified by click event";
｝
by the way, you could get rid of Text="On Load" in your aspx code. (your code would be: <asp:Label ID="Label1" runat="server"></asp:Label>, then add a page_load method in your .cs file:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
Label1.text = "On load";
}
in this case, it will display "on load" when you open the webpage, and it will display "Modified by click event" when you clicked button.
hope it

How to change MasterPage's label from Content page without refreshing page

I've got MasterPage and Content Page. On the ContentPage there is some label and i want to change it's text when clicked on button on the content page without refreshing the page.
Default.aspx
<%# Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" %>
<script runat="server">
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
Label SensorTemperatureLabel = (Label)this.Master.FindControl("SensorTemperatureLabel");
if (SensorTemperatureLabel != null)
{
SensorTemperatureLabel.Text = "TEST";
}
}
</script>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:ImageButton ID="ImageButton1" runat="server" OnClick="ImageButton1_Click" />
</asp:Content>
MasterPage.master
Part of the code with label
<div class="sidebar">
<!-- insert your sidebar items here -->
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Label ID="SensorTemperatureLabel" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
</div>

I have prepared you complete solution to show you how you can do this.
First sample master. Take notice I have added ScriptManager to page and target label is inside content template:
<%# Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="WebTester.Site1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Label ID="SensorTemperatureLabel" runat="server" Text="TEMP"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
Now here is content page, button is also placed inside content template:
<%# Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebTester.WebForm1" %>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Test" />
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>
And finally here is the code, I get refrence to label by using FindControl:
protected void Button1_Click(object sender, EventArgs e)
{
Site1 site = this.Master as Site1;
if (site != null)
{
Label SensorTemperatureLabel = site.FindControl("SensorTemperatureLabel") as Label;
SensorTemperatureLabel.Text = DateTime.Now.ToString();
}
}
This code will update label on master page without complete page postback.

If the label is not in <ContentTemplate />, you can access with javascript
var SensorTemperatureLabel = document.getElementById("<%=SensorTemperatureLabel%>");
SensorTemperatureLabel.innerHTML = "newValue";
Otherwise, the ID is generated and you'll need
var SensorTemperatureLabel = document.getElementById("<%= this.Master.FindControl("SensorTemperatureLabel").ClientID %>");

I hope my answer help in this case
if you have Label in master page named " Label1" then
you can change value there like this
VB
Dim lb as label= me.master.findcontrol("Label1"):lb.text="Hello worold"
Peace upon you all.

The one solution I found is to remove OnClientClick handler and use the javascript below:
function pageLoad() {
var tabContainer = $find('<%= TabContainer1.ClientID %>');
var hfd = $get('<%= HiddenField1.ClientID %>');
var oldSetActiveTab = Function.createDelegate(tabContainer, tabContainer.set_activeTab);
tabContainer.set_activeTab = function (value) {
if (value.get_id() == '<%= Panel3.ClientID %>' && hfd.value != "-1") {
alert("oops");
}
else {
oldSetActiveTab(value);
}
};
}

How to access controls in a list view row

I have listview and every row has a Drop Down List and a hyperlink control.
What i'm trying to do is change the navigate url for the hyperlink based on the selection of the drop down list. How would I get the row that the control posted back from so I can find the hyperlink control?

You may try the following:
<%# Page Language="C#" %>
<script type="text/C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
MyList.DataSource = Enumerable.Range(1, 5);
MyList.DataBind();
}
}
protected void DDLChange(object sender, EventArgs e)
{
var ddl = (DropDownList)sender;
var link = (HyperLink)ddl.Parent.FindControl("MyLink");
link.NavigateUrl = ddl.SelectedValue;
link.Text = ddl.SelectedValue;
}
