I'm trying to build a custome gridview control. now I've gotten quite far and I am now a bit stuck. I have a property that allows me to specify the columns datatype.
Now when I specify either a datetime or date variable I need to format it properly. Thing is, if I use a database other than sql server how can I format the dates properly. ZI want to make my grid as reusable as possible.
If i use date.tryparseExact I need to know the foemat of the date value being passed in. Problem is, I won't always know the exact format.
I was asked to build a couple of small and basic websites, without the use of database connections, just plain forms with information and a couple of images and forms. So my question is, if I only use those "html" controls of the toolbox, the performance of the site will increase against those with lots of .net controls?
Some one told me to use php or any script language to do that kind of stuff, but I only know to code in .net.
I have a dialogue window that contains an Accordion Control that is dynamically built. The only thing that appears on my source page is the opening and closing tags for the control. The panes and the controls that appear on the panes are all added dynamically based on records in a database.
Now here is my situation, if a certian action is performed on one of the controls then I want to save that controls data and make it no longer available for use, this was easily accomplished by having the control hide itself. An issue arises though when I have hidden all of the controls on a certain pane, the header for the pane still exists and this is not the desired result.
What I would like is to be able to dynamically remove the entire contents of the control and then re-build it. Due to the timing of the events in the page post back sequence, a simple call to the method that builds the control will not work and if an explanation is required I will provide one. Also, looping through all of the panes and the controls on each pane will not work since after the first pass through the loop the panes collection is mutated, the enum table for the control is no longer correct since the initial pane has been removed, as a result the for loop throws an error.
Can any one come up with a way that I can clear out the control, keeping only the basic empty structure, and re-build it all in a single post to the server?
I have declared a variable as public (Visual Basic 2008). As a result I can call its value in all subroutines. However I cannot change its value in any of the subroutines?! How to do that? The variable I'm having trouble with (see code below) is called 'antwoordbestand' and I want to change its value in subroutine startKnop_Click.
I am trying to figure out what are the basic assemblies required to run a basic ASP.NET 4.0 website. Say.. a website with just a label in it. I looked online and didn't find a list there. I know installing the framework 4.0 will give me all the dlls but I just need the basic ones that will make a basic site work on ASP.NET 4.0.
I want to use forms authentication on my ASP.NET MVC site. All I need is a place for users to login, a page to add a user, and a page to edit a user. I'm using all the default ASP.NET forms authentication tables for SQL Server (aspnet_Profile, aspnet_Roles, aspnet_Users, etc.). The only difference is that I've added an Employees table to my database, which contains a FK to aspnet_Users to create a one-to-one relationship. The Employees table contains columns for FirstName, LastName, StartDate, etc. It's a way for me to keep additional information for the users.
I'm having trouble finding any sort of tutorial that would help me build a basic page in MVC, everything I find is for WebForms. For my page to add a user, I'd like there to be fields for the Employees table. I don't know if I can modify the CreateUserWizard to add those fields, or if I'd be better off just creating my own custom page.
I'm looking at server controls for the first time, and I've a question about this code:
[Bindable(true)] [Category("Appearance")] [DefaultValue("")] [Localizable(true)] public string Text { get { String s = (String)ViewState["Text"]; return ((s == null) ? "[" + this.ID + "]" : s); } set { ViewState["Text"] = value; } }
I do not understand why this control returns the [id] or the text that is set. I do not see how this makes any sense. Is this just for demonstration or is there a reason for returning the id?
I am trying to build a master detail functionality. It present, there is a web page i.e. page1.aspx with search functionality. When the criteria is entered then the search button can be clicked and then the GridView gets populated with data. In this GridView, a number of the fields of the selected row can be edited as per business requirement. Now I would like the user to be able to see and edit more fields related to the selected row in the gridview. These are extra fields which are not viewable in the gridview. Question: Is it best to have another page i.e. page2.aspx to see and edit these extra fields or is it better to have these extra fields (One in each control) just below the gridview in page1.aspx?
I found the tutorial below to build a chat application for asp.net which fulfilled most of my requirements, i.e. written in vb and made use of database, however the second part is missing. [URL]
I was hoping someone may be able to point me in the direction the original author intended to extend this to cover multi rooms and hopefully multi users?
I have a gridview control on .aspx page. Situation is, the columns in the gridview control are not databound. I query the database and load the gridview control using the following code.
The gridview control shows about 13 columns from the database. But we want the user to be able to edit only one column. Rest of the 12 columsn should be read only. When the clicks one Edit button button, as usual the Update and Cancel buttons should come up. It is not happening. Only the _Rowediting event is getting trigged. Following is the code from my .aspx page. I don't know anything about template columns and not sure if I have to use that concept in my situation.
When working with an ASP.Net application, when I rebuild the solution, I would like it to automatically refresh the current version thats running through the integrated server in the browser.
I have looked through post build commands and afterbuild targeting but I have not been successful so far. I would like to do this straight through VS2008 if possible without needing to install anything extra, put if thats not possible then any solution would do!
So here is the problem, when I build my web application in Win 7 x64 and publish (copy) to 2008 Server R2 (also 64 bit), the application won't run when I navigate to a page that uses a 32 bit dll.
When I boot to the Vista x86 partition and build and publish (copy), same code, minimally modified sln file to redirect to same code location. I've created a new entry usiong Menu > Build > Configuration Manager and created a x86 entry. I thought that was all I needed to do to force VS to build to a 32 bit machine. Am I missing something or do I just need to boot Vista when I want to work on my web site?
I find myself always repeating code when it comes to gridviews. I want to build a usercontrol so I can just set a datasource andcolumn types etc and I can use the same control over and over in different projects.
I am having problems with a user control. I want my solution to have a separate project for holding my user controls.The main project can get a reference to this user control project and can import this user control dll into my main project.
Im very new to ASP.net and have no experience with it at all.Im currently developing a website,and am confused about creating users.Im using the create user wizard,everything is working fine.However,I am worried about the security of user information.I believe the user information is stored in the APP_Data folder, am I right in believing that this folder is secure?
Exactly how is the user information stored when using the create a user wizard?In a database in the APP_Data folder?Is it encrypted automatically when a user signs up?
VWD 2008 Express. Visual Basic.I have a customvalidator on my page and a corresponding OnServerValidate routine tied to this control in my VB code behind. I also have a "Save" button that is defined as "CausesValidation=True." I placed a breakpoint in my OnServerValidate code for the customvalidator and a breakpoint in my OnClick routine for the Save button. What I expect to happen is that when the "Save" button is pressed, all the validation is checked before ever entering the OnClick code for the Save button. If any of the validators are false, then I expect that the Save button OnClick code will not run.
I'm looking for recommendations for a basic site search control or example of creating some code to provide a way for users to search a site I am developing. I'd like to keep it quite simple if possible and ideally want something I can use straight away.
I have a situation where I currently have a HyperLinkColumn control that I would like to modify to have a Label or simple text appear in the same column as the hyperlink.
