In my web application, i have declared modalpopup extender and corresponding div(popup control) inside master page to make it generic. In my page i am using updatepanel with a button inside it. Clicking on this button will fire the modalpopup extender. Before calling show() of modalpopup i am setting some text to a label inside the popup control. But when the popup comes, the updated text is not showing.
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.
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 a web form for payments which consists of a DropDownList (credit card, purchase order, bill me). By default, credit card is selected, and the form (a ListView within a UpdatePanel) is loaded with the user's billing address. If the user changes the payment option, the form fields change -- for example, if purchase order is selected, the billing address + credit card fields disappear and a "Purchase Order Number" textbox appears. This is done using an AsyncPostBackTrigger associated with an event in the DropDownList.My problem is that when the form is submitted, I cannot see the user-entered values within the UpdatePanel/ListView, but I can see the original values loaded in the ListView before the edits were made. For example, if purchase order is selected, I can see the billing address from the ListView, but I cannot see the newly-entered Purchase Order Number from the ListView.Here's an abbreviated version of my code. I've bolded and commented two lines where the problem appears:
I want to trigger two Async Postbacks at once using UpdatePanel's via their associated buttons such as the example at the end of [URL] When you click the first button, then immediately click the second button, the first button's message never gets updated. By clicking the second button, the first async Post back seems to be cancelled. Why does this happen?
I saw this article about only allowing one postback to occur at a time here: [URL] Is this the desired behavior for Multiple update panels? Can only one run async code at once? What's the point of it being async if you can't do multiple at once? Here's what I'm trying to do overall: I want a webpage where I click a button which causes C# code to search a certain webpage and parse it. Based on the parsed information, it should automatically start searching multiple other webpages. All the while, I want the web UI to be updated with the progress.
Button Press and the client UI says "Searching..." Then the webpage is found so I want to display "Parsing..." Then the webpage parsing is complete and multiple other websites are searched at the same so the UI will display:
Then when the Webpage 1 -3 are done updating, they change their progress message to Complete. I just started looking into ASP a few days ago and I have two ideas how to approach this problem: zy first idea was to use UpdatePanels and UpdateProgress because they seemed easy to get in there. However, the part of updating multiple webpage status messages at once doesn't appear to be possible since I can't have two UpdatePanels updating at the same time to make changes to the client UI. The one that is started second takes over the processing and the client UI isn't refreshed until that second asynch postback is complete. Ideally, there would be a way to refresh the UpdatePanel's mid postback............
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.
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.
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 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 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.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 get the problem in updating the treeview nodes from databse.i have created a dropdown list and on selectionindex change event i written the code for selection of nodes in the treeview.on first time selecting the option in dropdown list i get the selected nodes which works fine..but when i change the option in the dropdown control the treeview nodes cant updated on page but it seems selected as per database in the code behind when i debbug it
I have a page with two updatepanels both which have thier triggers outside of the panels themselves - I am setting the triggers using in the pageload event. This is how it works - there is a repeater that holds a list of links which gets set when the page loads (this is outside of the update panel). The first udpatepanel has a trigger set to the itemcommand of this list of links - it then goes out and gets the sub links and fills a repeater that is located in the update panel. - so forgetting all about the second update panel on the page... If I set the panels updateMode="conditional" then it doesn't render till I click the link twice. If I put a breakpoint in the code I can clearly see that the code is executing and that there is no error but again... Nothing renders
- I click the link again it renders. If I take out the UpdateMode="conditional" statement all is well... But I don't want that cause I two update panels on the page.
The second one also has sort of the same problem - The trigger I have set for it the ItemCommand for the repeater in update panel one... when I click one of the linkButton's in the first updatepanel sure enougn I see the code execute return my results and all seems well however there is nothing rendered on the page. BUT!!! When I click one of the main links on top (remember these are trigger for updatepanel one) my second repeater inside of updatepanel2 is shows up on the page.
What is causing the partial postback not to render anything?
I know this is confusing so I hope I explained myself well enough. I will just post the ASPX so you can see how I am setting this up - I don't think you need to see the code behind... If anyone does then I will post it.
Again - all this is to with the updateMode - when I remove it (as I did in this code sample) it works and renders however I don't want both updatePanel to get updated at the same time.
