Web Forms :: Change Label Text With C# Behind Code?
Dec 29, 2010
I created a new project in VS2010. It automaticly creates masterpages and other stuff.
In the login page i create a connection with my local database. To test my login-routine i want to change te text of a label.
I wanna do this with behind code (C#).
But i continue get errors that the refered label doesn't exist: Error 1 The name 'Labeltest1' does not exist in the current context l:DocumentenVisual Studio 2010WebSitesWebSite1AccountLogin.aspx.cs 46 13 l:...WebSite1
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".
I have an asp page with a textboxes, labels and other controls. I cannot get the .text to change in any of these controls. I click on button which I execute code that I expect to update the text but it doesn't work. Something like Textbox1.text = "Hello" Are there page level properties/settings I should look at? I am perplexed an looking for a place to start. I will provide more information as needed. I just don't know where to start.
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?
How to accomplish the below:Whenever users selects a row in the gridview, "text" of a asp.net label control changes from 'A' to 'B'. Both label and gridview are on the same aspx page.
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?
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:
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.
I have a User Control with a label on it. I have a Master Page that I have dropped the User Control on. I have other .aspx pages that use the master page that has the user control on it.
What is the best way to change the text of that label on the user control from the .aspx page?
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?
The 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?
