I wish to use asp.net gridview server control in asp.netMVC. But while binding data I'm not able to bind the data and if I place the attribute allowing paging =true, it is throwing an exception. The data source does not support server-side data paging.
My code for databinding is
<% GridView gv = new GridView();
gv.AutoGenerateColumns = true;
gv.AllowPaging = true;
gv.PageSize = 5;
gv.DataSource = Html.Encode(ViewData["Employees"]);
gv.DataBind();
StringBuilder sb1 = new StringBuilder();
System.IO.StringWriter textwriter1 = new System.IO.StringWriter(sb1);
HtmlTextWriter htmlwriter1 = new HtmlTextWriter(textwriter1);
gv.RenderControl(htmlwriter1);%> <%= sb1.ToString() %>
I have a login control that is working beautifully on my localhost, but not working on the server. It validates my username & password - and gives me an error if I enter an invalid username/password. However, if I enter the correct username/password, the page refreshes, but does not redirect me to the "ReturnUrl" that I see in the URL. I've seen posts on this, but nothing that I tried worked. I've tried setting the 'MembershipProvider'attribute of the login control. I don't want to set the DestinationUrl...I want it to take what is in the ReturnUrl in the querystring. I don't think it's a web.config issue cuz it works on localhost??
i m facing a issue in my code i m calling a user control which is in master page, and in row databound i m calling it and it is working fine but on select index change of checkbox it is not working
I have used Ajax control Toolkit(1.0.11119.20010) with ASP.Net 2.0.My website working fine at local network and ajax control functioning well but at server end ajax control not functioning, my website running and not throwing any error but whatever ajax control i have used is not functioning at server end..Following dlls are included in project: AjaxControlToolkit, AjaxExtensionbox, System.Design, System.Drawing.Design, System.Web.Extensions, System.Web.Extensions.Design
I have created an application in Microsoft Visual studio 2005. And I have used Ajax control tool kit version 3.031106.0. It works fine in my local system. When I hosted this on the server,I am getting this following error.
"Could not load file or assembly 'AjaxControlToolkit, Version=1.0.10606.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' or one of its dependencies"
i use a asyncfileupload control to upload files from my web pages. since i have a listview inside an update panel, and the listview needs to have the file upload functionality, i can not use a asp fileupload control.
the uploaded files are saved inside a temp folder in my application directory. i use a asp:button to upload files from the asyncfieupload control to my temp folder.
as long as i work on my local machine, the upload control inside the listview works perfectly fine, and does what is expected of it (i.e upload files :))
but when i move the code to my web server the asyncfileupload onthe page works just once, that is, it uploads just once (no matter whichever row of the listview it is) and for all other subsequent uploads, it uplaods a file of the same name to my temp folder but with 0KB size.
it beats me why asyncfileupload control would behave this way in the two environments.
could anyone suggest a possible reason/or something i m missing to configure on the server?
I am developing a large dent in my forehead trying to figure out why my server control will not display the property editors, both image and URL navigation. I have done everything that they say on the different sites but the editors will not show up, here is my code:
#Region "Imports" Imports System Imports System.Collections.Generic Imports System.ComponentModel Imports System.Text
I made a login control in a webapplication with a membership provider and a role provider. The problem is when I enter the username and the password in the login control (on my system i.e localhost) the user authenticated and redirected without any problem, but when I deploy my webapplication with my database on a host server the login control cant authenticate the same user and tells me "Login attempt was not successful".
while i was using flash movie on my application nobody was able to watch it . However I know the reason that is flash plugin should be installed on client side. So here i want to deploy a msg or utility to install a flash plugin as:
there should be a button having text install flash plugin now and on clicking it setup should execute on client side so that it will run setup and every body will be able to watch it.
I am using AjaxControlToolkit(1.0.11119.20010). It works fine at local machine but not functioning at server end. It dosent give any error at server but any control of Ajaxtoolkit what i have used in my project is not working.

I am a newbie to asp.net and have recently been building a web... I have a login control on the main page which when logged in verifys the user and redirects them to the home page... I published this to the server previously and it worked. Today when I tried logging into my system however I got the following error message:-
"Your login attempt was not successful. Please try again."
The accounts did work before but since I have uploaded a newer version of my program onto the server the above message is displayed. I have been on many websites and read previous forums with suggesstions to add <roles> in the web.config file however the login control worked before and I have not changed anything on the site apart from a different page that doesnt affect the login.
Few points to make... the login control is using the asp.net configuration pre built tables it generates for you, I have created the users and roles inside of asp.net configuration so it is not a custom membership... I am at a complete loss as how to get my login control to work having tried to insert roles into the webconfig file.
I started to work with this control and I find it better to code it my self instead of using the wizard option that comes as a standard. Can I pass the values directly to the Query in my SqlDataSource when I update a row? Let me show you the code: <asp:SqlDataSource ID="SqlDataSource" Runat="server" SelectCommand="SELECT [catCodigo], [catDescripcion], [catSite] FROM [Categories]"
My problem is Asyncfileupload control is working fine when i debug the application and upload large file...but when i run this from iis it only upload file less then 5 kb. why is that so?? i did try adding Httpruntime maxRequestLength="4096" i tried to find on search but no help... did m i mising any settings..??
I have a gridview control on a .aspx page (content form).
Paging is enabled on gridview control. It displays the page numbers at the bottom of the .aspx page. When I click on a page number say 3, I get error saying the "Exception Details: System.Web.HttpException: The GridView 'GridViewReconresults' fired event PageIndexChanging which wasn't handled."
Do I need to write special code to handle the paging? Because there is a grid in another page and it has bound columns and I didn't write any code for paging and it works perfectly fine.
Here is the code in the .aspx page that I have problem.
I have a simple .aspx page. Where I need to connect to sql server 2008 and show the records on the page in a gridviewcontrol. It will have Edit button on the gridview control. I am getting some weird message about the connection string.
Error message is: 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.ArgumentException: Keyword not supported: 'initial catalog'.
Code: <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString_SqlServer %>" ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>" SelectCommand="select name, value from dbo.Pricing order by name asc" > </asp:SqlDataSource>
I an expanding on the HotGridView control (http://msdn.microsoft.com/en-us/magazine/cc163612.aspx). During testing I noticed the "AutoGenerateCheckBoxColumn" behavior was returning true even if the user did not specify the a value in the markup but I expect it to return False if not value is supplied by the user - can anyone shed some light on why the AutoGenerateCheckBoxColumn is always true if not explicitly set to False in the markup?
I need to create a reusable custom control,which is like a form containing a listbox and some fields.The fields can be either textbox or combobox as needed for different applications,which can be selected on the property of the form onwhich page that i am using it,also i needed to specify the number of fields in that property.And also need place 3 buttons below for edit and delete the selected item in the listbox and a button to save.Data will be binded from the database as needed for different applications.
tell me with code how to create it using asp.net server control in C#.
