.NET Label Text Doesn't Change?

Mar 21, 2011

I have a form setup with a drop down list, a label and a button. The dropdown list is populated from an XML file and the label is initially filled in blank. The label text changes depending on the drop down box selected item and as I didn't want to have to cause the page to post back each time the user selected a new user item I set the label text in JavaScript using the .innerHTML property.

However whenever I submit the form the label text doesn't get passed through properly it always outputs "". As a test I tried setting the label to a default value in ASP.NET and as expected the result that gets passed through is the default text property.

So it seems that it doesn't like JavaScript setting the text property of the label control (which renders as span). Is there a way for C# to read the innerHTML property of the field?

Forms Data Controls :: Gridview - Dynamic Label - VB.NET - Change The Text Of The Label If Certain Criteria Is Reached?

Mar 15, 2010

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>

Change Label Text As Per Tab Selection

Feb 25, 2011

I have a 2 tabpanels in my tabcontainer and both the panel has their own header text. I have put the tabcontainer inside a table. Above the table (OR tabcontainer) I have a label and what I am trying to do is ... changing the label text as per tab selection ... code below:

if(tabcontainer.activetabindex == 0)
{
label1.text = tabpanel1.headertext;
}
else {label1.text = tabpanel2.headertext;}

But this is not working ... even if I select the panel2 my label displays the same text as panel1 header text ... it's not changing as I want.

Label In Repeater - How To Change Text On Output

Jul 2, 2010

I tried this technique as suggested on another forum and a couple of other things, suggested on SitePoint as well as others but to no avail. Im trying to find the Label in the repeater to display information depending on the output. However I was presented with the following error:

"Index was out of range. Must be non-negative and less than the size of the collection.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index"

It highlights the problematic script as:

Label lblStatus = rptGeneralEnq.Items[0].FindControl("lblStatus") as Label;

I'm trying to access the Label, in the repeater, so that depending on if the text origionally displays true or false (as the label grabs the 'bit' datatype for that record to display) to then change the text to something more appropriate (completed/outstanding) - if at all possible.

Heres my attempt:

C#:

Aug 18, 2010

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.

How To Change Label Text/visibility When Inside A Datalist Or Repeater Using VB

Mar 19, 2010

aspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.
