I have an ASP.NET project using C#. I'm loading data (Username, email, etc...) from a sqlite database with C# (using ADO). I'll be loading the data into static Global variables in a class file in my App_Data folder. I need to be able to insert the username into an ASP.NET Label on a page during load.

I need to get the text value of a label which is binding a field insiede a datalist. I can get the value by clicking a button but I need to get this value on page load so that I can make it page.title. here is how I am getting it by clicking a button (also button is inside the datalist);

Here is my page code;

So how can I get this value in page load event. I tried some way but didn't work.
I have a label on my page, and in Page_Load I have
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Label1.Text = "dog"
End Sub
This works when I run it locally, but not when I upload it to my host. The label does not change. what is going on?

When i write long text it gets expands and disturbs the interface so kindly tell me how to limit the text.
Anyone have this problem. When you write a ex. label name or label text in the properties window, it look like its updating the text before you actually are finish. This make you type over what you allready wrote. Its not a big problem,
View 2 RepliesThe Datalist is being databound via an ObjectDataSource and everything here works fine. I have a label which I've added to my datalist and it's unbound to anything. Depending on the message information, I want this unbound label to display a certain phrase but it has to be next to a bound label. But if I try to change the text of the label in the code-behind, VS2k8 reports that the label is not declared. How do I do this?

I am working on Scott Mitchell's ASP.Net in 24 hours book. I am running into what looks like a simple problem that is getting the best of me.
When a page loads, the UserId of the currently logged in user will be retrieved in the page Load event and placed into the Text value of a Label. But, when the page opens when I am running the app, I am getting an error in the lower left corner of the browser. When I open up the error message, I see this:
Webpage error details
Message: 'UserIDValue' is undefined
Line: 92
Char: 1
Code: 0
URI: http://localhost:51035/PhotoAlbum24hrs/PhotoAdmin/ManageCategories.aspx
Here is the web page's Load event (VB) code:
[Code]....
Here is line 92 and the surrounding lines from the page source when I run the app:
[Code]....
This matches what is in Scott's book. (Or else I have been looking at it too long and have missed something.)
If I make the UserId Label visible, I can see the logged in user's ID displayed on the page. So, what is going on here? Why am I getting this error?
I have a label in the master page
<asp:Label ID="lblLogName" runat="server">Test</asp:Label>
I have created a public property in the master page
Public Property LoginName As String
Get
Return lblLogName.Text
End Get
Set(ByVal value As String)
lblLogName.Text = value
End Set
End Property
I have written a page directive in the content page
<%@ MasterType VirtualPath="~/Site.Master" %>
I am trying to set the value of the label in the master page by
Master.LoginName = LabelName.Text
But the value in the master page label is not changed.
I have a protected function in the .cs file:
protected void func()
{
Label1.Text = "helloworld";
}
In the markup, I have this code:
<% func(); %>
Why is it that when it goes through the code, the Label1 control does not have text "helloworld"? In debug mode, I know I am hitting that line of code, but it won't show up in the label1.
i have a ListView with some labels (this labels can be increment[+1] and decrement[-1]) by the user via buttons. now i have the problem, that each of this list items have a details view at which the user can look at. but when he return to the overwiev page, all labels ar set back to the default 0.
how can i solve this problem, so that the user returns from the details view to the overview, that he see all the changed label values.
i have setup a profanity filter with bad words in a XML file and have the following function to run on my page to replace the words:
BadWordFilter.Instance.GetCleanString(TextBox1.Text);
i'm about to go through my entire site now wrapping that function around every little text variable one by one and it's going to be a huge pain in the butt
i'm hoping there's a way that i could just set my masterpage to automatically run all text through this thing on any page_load, so that the effect would be site-wide instantly. is this possible?
i use asp.net and c# to build my web application.i'm trying to display message dynamically using ModalPopup extender.I add the event inside a loop and the message is selected according to my logic.My issue is that the label stays empty, it seems that the set does not take effect, so the popup comes up empty.
the code:
<asp:Panel ID="pnlMsg" runat="server" CssClass="modalPopup" Style="display: none">
<asp:Label ID="lblModalMsg" runat="server" ></asp:Label>
<asp:Button ID="btnOk" runat="server" Text="OK" />
</asp:Panel>

The following jQuery code lets me hide and open a panel and set focus on a textbox depending on the setting of a RadioButtonList. There are few problems I have with it (discussed below code).
[Code]....
Problems:
(1) Focus doesn't set on txtSpouse when clicked value is 0.
(2) When I put the function in a .js file, neither of the textboxes (txtSpouse and txtMaiden) receive focus.
(3) I need to unhide pnlMaiden when the page is loaded and rblGender value is 1.
I found that I don't need to use jQuery or AjaxToolKit to use a textbox with autocomplete instead using the AutoCompleteType() class.However, base in the documentation it says the autocomplete will just trigger after the button was click at first instance, with that
description looks like what I want to do will not be applicable.Is it possible to populate the textbox with a list of strings in page load? so that if I type in a textbox it will give me a complete list of strings already.
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>
I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'
I have alot of code in the page load event as below.
Is it best practice to use (!NotPostBack) and wrap the code in this block or does it depend on the methods etc. I also have code which populates ajax slideshow as well which gets images from database.

i would like to write the following within a div (myGallerySet) from behind code (vb.net) on pageLoad:
<div id="gallery1" class="galleryElement">
<h2>Brugges 2006</h2>
<div class="imageElement">
<h3>Item 1 Title</h3>
<p>Item 1 Description</p>
<a href="#" title="open image" class="open"></a>

Basically I have images details which are stored in a database and would need to dynamically added hence, why i need to write within a div container.
I am beginner to .Net development, so i am looking for a favour.
Question 1 :
protected void Page_Load(object sender, EventArgs e)
{
txtUserName.Text = "Focus";
txtUserName.Focus();
}
I am unable to get focus to my textbox
Question 2 :
I made javascript code for client side validation.
function loginjs()
{
if(document.getElementById('txtUserName').value.length==0)
alert("UserName cannot be blank");
else if(document.getElementById('txtPassword').value.length==0)
alert("Password cannot be blank");
}
this code executes but it is not stopping further code execution. I mean it is only alerts but in addition to that i need to stop further execution.
