Forms Data Controls :: Trying To Change A Label's Text Property And Colour Properties Depending If An Event Occurs On The Page Behind File?
Jun 4, 2010
I'm trying to change a Label's text property and colour properties depending if an event occurs on the page behind file.
Does anyone have a similar issue?
if (((Label)FindControl("Label1")).Text != null) - //getting Object reference not set to an instance of an object.
{
Label Labelmerchantid = (Label)FindControl("Label1");
Labelmerchantid.Visible = true;
Labelmerchantid.ForeColor = System.Drawing.Color.Red;
}

The dataGrid view is being populated. The Autogeneratedcolumns is set to false. How do I change the colour of a cell of a row depending on the text? i.e. Row 2, column 5 says "Failed". I would like to change the colour of that cell to be red.

Access to my application is controlled by user accounts. I would like my text labels to change within my pages depending on the user logged in. This needs to be easily managed.
What is the best way to achieve this? Would using the resources file work?

I have a gridview and I use a sort function there, which means that if I click on the header of some column the table is sorted by this column. What I need is to change the colour of header of column which I sorted the table by. E.g. if I sort the table by first name, I click on the header of column called "first name", then the table will be sorted by first name and the colour of the text "first name" will change. The sorting is not a problem but I don't know how to change the colour of text.

I have asp:Table with number of asp:Label inside asp:FormView, it represents short stats info.I need to set Label.CssClass to "red" if it's text isn't "0".Currently I do this on FormView.DataBound event. But think that it's better to use JavaScript and probably jQuery. How can I do that?

I was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.

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 a component which is listening a server from TCP/IP.
When somebody connects to the system my component's Connected event is fired.
I want to write to a label when this event is fired without postback.
I used UpdatePanel. And I know about AsyncPostBackTrigger.
But my component is not a visual component. So I declared in codebehind. So I can not use AsyncPostBackTrigger.
How can I set my label.text value when component's event runs.

i want to generate the output of an asp.net page by reading a text file, get the controls out of the text, change te properties of these controls, render it and displaying it.
so for example, the text file may contain:
<head>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<sys:Label ID="Label1" runat="server" Text="empty1"></sys:Label>
<sys:Label ID="Label2" runat="server" Text="empty2"></sys:Label>
</div>
</form>
</body>
</html>
after reading the text, i would like to change the properties of the sys:label controls. After that, the text will be rendered, and displayed.

I have implemented master pages using this example How to implement a status bar in an ASP.NET application?. I have a property on my SiteMaster.cs inherited MasterPage called Environment. On my MasterPage.master I have this code:
<body>
<form id="frmMaster" runat="server">
<.. some content removed for brevity ...>
Environment: <%= this.Environment %>
</form>
</body>
What I would like to do is evaluate this.Environment and if it is "LIVE" then colour the background of this.Environment text red, and if it's "TEST" colour it yellow. How would I do this?
UPDATE I've just added this code to MasterPage.master
protected void Page_Load(object sender, EventArgs e)
{
lblEnvironment.Text = this.Environment;
if (this.Environment == "LIVE")
{
lblEnvironment.BackColor = System.Drawing.Color.Red;
}
}
The page loads, but the text does not get set, it's blank! Also the old text, that was populated is now blank too (I left the old code there for now). I also get a warning in Visual Studio:
'ASP.masterpage_master.Page_Load(object, System.EventArgs)' hides inherited member SiteMaster.Page_Load(object, System.EventArgs)'. Use the new keyword if hiding was intended.
UPDATE2: This is what I have in SiteMaster.cs
using System;
using System.Web.UI;
public class SiteMaster : MasterPage
{
public string StatusText { get; set; }
public string StatusTime { get; set; }
public string Environment { get; set; }
protected virtual void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
if (Session["status"] != null)
{
this.StatusText = Session["status"].ToString();
this.StatusTime = Session["statusTime"].ToString();
}
this.Environment = Session["environment"].ToString();
}
}
}

Kindly, see the following image. This is my Gridview with separate paging on the top right of the image. The arrows are Image buttons and the right text box is read only.[URL]
I run my page for the first time everything runs perfect. I move to other pages of the grid still perfect. Then i move to other aspx page and then come back. The page loads perfect with the old page number there still perfect. Now if i press any image button then the text change event fires which should not fire.
Note: i need the text change event as i user randomly enters something in the text box then i have to handle that.
Example:
When i return from the other aspx page then the value in the Page Number text box is lets say 4. Then i press the Back image button and a post back happens. The Value in Text box is still the same 4. Then y the event is firing ???
I am not understanding that why this event is firing. On the page load, i retrieve the values from hash table (The hash table is stored in session in base page) and from the hash table i get the pageNo and assign it to the page No text box.
Here, is my one of the image button event. (Remaining image button events are almost same)
