View 7 RepliesI want to data bind jQuery Counter just like we do to Ajax Counter. Also I would like to know that do we have events for jQuery counter just like we have a tick event in Ajax Counter?
View 9 RepliesI have a grid view that always displays even number of rows. Is it possible to apply same styling for two contineous rows. So for example there would be different background color for rows no 1,2 and 3,4 I would prefer to do that in code behind.
View 4 RepliesI have a webpart with - amongst other things - a button, that queries an external Oracle Database in the onclick handler. The Oracle server in question has high traffic and the connection fails from time to time. To counteract this, i've set up a loop to retry a specific amount of times. To inform the user, i want a Label below the button that gets refreshed if something happens. This is my current code :
[Code]....
In the click handler, i have something like that :
[Code]....
However.. this doesn't work because there is no actual postback within the event handler.
I have a small C# ASP.NET app, and want to include an Ajax progress counter. The architecture is currently like this: Web Application --> calls a class that does the upload For example, in default.aspx, I call :
FileHelper fh = new FileHelper()
fh.MoveFiles(file)
I have an Ajax control that fires when the above is called. This is a control that resides on the website class/project. How do I update the progress counter from the Filehelper class? (I don't think calling the control directly would work as it would be a circular reference)Also how do I continuously update the counter?
I have seen several websites that show you a real time update of what's going on in the database. An example could be. A stock ticker website that shows stock prices in real time Showing data like "What other users are searching for currently.." I'd assume this would involve some kind of polling mechanism that queries the database every few seconds and renders it on a web page. But the thought scares me when I think about it from the performance standpoint.
In an application I am working on, I need to display the real time status of an operation that a user has submitted. Users wait for the process to be completed. As and when an operation is completed, the status is updated by another process (could be a windows service). Should I query the database every second to get the updated status?
I have a hidden field which is used to count the number of times "Load Grid" button is clicked. Load Grid button and the grid view are in update panel as shown below.
[Code]....
Code behind:
public partial class ajaxGridSort : System.Web.UI.Page
{
public string sortOrder
{
get [code]....
Each time user clicks on load grid or try to sort in the grid, I am loosing the hidden field values. Can you please help me understand why am I loosing hidden field data on AJAX postback and please provide the solution for this issue?
I don't know why, but even using update panel, my postback method updates the entire page. I'm using a master page with aspScriptManager inside.
My ASP.Net code:
<div> <asp:UpdatePanel ID="updProva" runat="server">
<ContentTemplate> <asp:Panel ID="pnlProva" runat="server">
</asp:Panel> </ContentTemplate> </asp:UpdatePanel> </div>
The CodeBehind (C#) creating some RadioButtonList controls in my ASP.Net page, I'll post the main function and de Page_Load:
createTest function
[Code]....
Finally, the Page_Load:
[Code]....
I have a user control that I am explicitely calling from an aspx page. In page_load of hte aspx page I have the following, myControl = (DynamicTable)Page.LoadControl("../inc/DynamicTable.ascx"); Then in my code where I want it to execute the control, I have this pnlESDDEnrolled.Controls.Add(myControl); where pnlESDDEnrolled is the panel I am loading it into for display. So, I execute the aspx page, it links off to the user control, populates the control, returns back to the aspx page and the page dispalys with the user control in the middle of it. All is well.
The problem comes in when updates are made on the user control. Keep in mind, that other data is updated on the page as well, and the update button resides on the page, not the control. Anyway, when the update button is pushed, the button_click event is fired on the page, but the updates that I made on the user control are lost. Since the page loaded the user control and then the usercontrol executed the page unload method, the page has no knowledge of the user control anymore. Thus, when the update button on the page is pushed, I guess I am not really sure what happens with the updated data on the user control. All's I know, it is lost.
I thought my issue was related to the Validators not working in UpdatePanels but that does not seem to be the case.
All validators fire when they should but, the error warning message clears when the updatepanel updates.
for example...
textbox1 range 1 to 23. dropdown1 updates the updatepanel. enter 99 error shows, but will disapear when I change value of dropdown1. textbox1 value still 99 so validator message should still show but it does not.
I've asked this before but I was hoping for another answer and perhaps some code samples because I've been having a difficult time with this. I have an asp.net page. The user hits the "Run" button and I have code IN AN ASSEMBLY, not in the APP_CODE folder that is called and runs a long process that moves product info from a file into the database. While the user waits, I would like them to see status updates like what product the import process in on and status info. I'm assuming I'd break off into another thread and use Ajax but I have no idea how to do this.

View 4 RepliesI have a two gridviews that I populate it through some tables from a database.
In the same page I have a ASP:Button with onclick event.
When click is perform I wish to write a code that compares the old values of both gridviews (that retrieved from database), with the new values, and if changes were made then create the changes in the database.
I think that the best way is to loop every gridview sepertly, and compares it with the values in the database
How do I do that? Do you have a sample code that loops on gridview and compares with the old values to detect changes?
PLZ find below my transaction. i feel that something is wrong in those lines especially in the insert in the table BARCOD0F .the gridview dont show the new updates .i closed the page and relaunch everthing but the updates are not considered
at the first sight my code is right???

So I followed Scot Mitchell's tutorial from asp.net/learn on adding a checkbox column to be able to select multiple entries and delete them with the click of a button. When I make my selection and click the button it works on the database end, as the desired entries are deleted. However, the entries remain on the page after it reloads. if I refresh the page it's updated properly but I'd like it to automatically update after the button is clicked.
Also, I tried his method for adding check/uncheck all buttons to the top of the gridview and they don't seem to be working either.
Here's the code behinf from the gridview page:
[Code]....
On update the dropdown value shows NULL in database : here's structure for my gridview
<asp:TemplateField HeaderText="Construction Phase" SortExpression="Phase_Name">
<EditItemTemplate>
<asp:DropDownList ID="EditedDropDownInGrid" runat="server" CssClass="form-control" DataSourceID="PhaseSQLDataSource" DataTextField="pp_name" DataValueField="pp_id">
</asp:DropDownList>
</EditItemTemplate>
[Code] ....
It updates other controls in gridview but does not update my selected dropdowns item value in Integer format which is inside gridview...
I have a website in C#/ASP.NET that is currently in development. When we are in production, I would like to do releases frequently over the course of the day, as we fix bugs and add features (like this: [URL]. If you upload a new version of the site or even change a single file, it kicks out the users that are currently logged in and makes them start over any forms and such. Is there a secret to being able to do deployments without interfering with users for .NET sites?
View 5 RepliesI need a Continuous integration tool that will support both .Net Unit tests and Javascript unit tests and perform the builds.It looks like my main options are CruiseControl.NET using JUnit and NUnit or Team City and JS Test Driver.
Are there any other options and which ones have you used or had good or bad experiences with.

View 5 RepliesI just released a new version of my web application on ASP.NET V4.0 (on IIS 7 Win2008 R2) For some reason, the application Restarts at (almost) every request. I cannot figure out what configuration (although I didn't change it) or code error may cause this problem. Mind this happens on a hosted server - so I have a somewhat limited ability to debug it.

View 2 RepliesI'm trying to make a progress bar that updates the user on the progress of the AJAX call.
My immediate thinking was that I need an AJAX call to start a thread on the server, allowing the starting AJAX call to finish, and allowing the thread to send updates back to the user.
For the purpose of simplicity, disregard the actual progress bar functionality (I was thinking of implementing one of those JS bars, with fancy colors and effects ;), but if I can get an update from the thread, then updating a simple JS progress bar becomes trivial ;) )
