Web Forms :: Store All Data Including Data From User Control Or Subroutine?
Oct 21, 2010
I have a user control with data of person. iN this user control is subroutine which storing data to database of person.On my ASPX page I've implemented this control and another form with data which ii'm storing.On button click on ASPX page, i want to store all my data including data from my user control or subroutine in that user control which storing data of person.I want to make sqltransaction, so only one connection for aspx page and user control.ASPX.vb
[code]...
The point of my question is how to interact between my class where i have methods and user conttorl on aspx page.
I have one parent gridview where each record will link to its details page (another child gridview in modal popup). May I know how do I store the values of the child gridview temporary (maybe in session) and repopulate the data into the parent gridview? Current problem is: once I click save in the child modalpop gridview, it binds the parent gridview before the child gridview data is stored in session. I want to store the data temporary until user click save in the parent gridview.
I'm trying to pass in an ID of an activity (RefNum) to my codebehind via OnDataBound called in the CheckBoxList, but can't seem to find the correct syntax.
I know I'm supposed to use parentheses when passing parameters to subroutines and methods, and I've tried a number of ways and keep receiving the following error:
BC30203: Identifier expected.
So I tried to hard-code it in the code below [ OnDataBound="FillSectorCBList("""WK.002""")" ], but it's obviously wrong. :(
I have a GridView control which is populated by an SQLDataSource. When I select a row the details are shown in a DetailsView control. Is it possible to intercept the select and run a VB subroutine at the same time so that I can make a Panel in a separate part of the page disappear?
I am not trying to activate an event or run a subroutine from a control from the masterpage, I am trying to activate or run from VB codebehind of the master page.
I have a button in a content page with a particular .click even that I want to activate from the masterpage codegehind periodically.
Also, how do I access or run a subroutine in a content page from codebehind in a master page.
I am currently trying to implement a small class attendance system, where the student names are taken from a database, stored in a List<Student>, and bound to a Repeater control. Each row of the Repeater contains two columns: The first is the student's name, and the remaining column contains a RadioButtonList with three ListItems (Present, Absent, Sick).Now, once the user presses "Submit", I want to be able to store their attendance status based on the user selection. However, after submission, the SelectedIndex is always 0, no matter what option is selected.
I'm am building an web application that needs to be able to scale.We want to store, an connection string, an object that says what organization the user is working on right now and the identity of the user.
We could serialize down this and send through the userdata property in the FormsAuthenticationTicket, but that feels to not be the optimal solution, cause its is 4-5 strings of data that is unncessesary, but the main issue is that we are sending an encrypted connectionstring to the user which we dosent want to.
So what are our options?Can ASP.NET Cache be our solution?, can we couple the expiration of the asp.net cache and the formsauthenticationcookie?
I have an application in which a user can choose from different (learning)groups. User has only access to registered groups. When the user enters the site, he can choose (in a dropdown) which group he wants to see, so the complete site filters content related to that group. So every controller needs to access this global "group" object.What is the best way to do this in ASP.NET MVC? I've thought about a BaseController or ActionFilters. Is there any other best practice?I've build a WebForms application and there I used a BasePage so that any other page has access to the group.
I'm using the ASP.NET SQL Membership Provider. So, there's an aspnet_Users table that has details of each of my users. (Actually, the aspnet_Membership table seems to contain most of the actual data). I now want to store some per-user information in my database, so I thought I'd just create a new table with a UserId (GUID) column and an FK relationship to aspnet_Users. However, I then discovered that I can't easily get access to the UserId since it's not exposed via the membership API. (I know I can access it via the ProviderUserKey, but it seems like the API is abstracting away the internal UserID in favor of the UserName, and I don't want to go too far against the grain).
So, I thought I should instead put a LoweredUserName column in my table, and create an FK relationship to aspnet_Users using that. Bzzzt. Wrong again, because while there is a unique index in aspnet_Users that includes the LoweredUserName, it also includes the ApplicationId - so in order to create my FK relationship, I'd need to have an ApplicationId column in my table too. At first I thought: fine, I'm only dealing with a single application, so I'll just add such a column and give it a default value. Then I realised that the ApplicationId is a GUID, so it'd be a pain to do this. Not hard exactly, but until I roll out my DB I can't predict what the GUID is going to be. I feel like I'm missing something, or going about things the wrong way. What am I supposed to do?
Using SQL and C#. I have a gridview with a template field. I need to modify the some items in the gridview when the user selects a given record and store the values back in the database. ProjectID is the unique key in the database.Gridview is done as a table. How can I do it? Here is my grid view implementation.
I created a Textbox named VisitorName. The visitor puts in their name and it goes in VisitorName.Text
There is a Label that says "Which do you own?"
There is a RadioButtonList. It has Cat, Dog and None.
There is a button that says Add to list.
The button needs to add the results of the above items and put them in the list.
Now you keep adding people and their pets.
Once there are all entered you press send and I get the results for everyone entered during that session via email.
I have no database access and the information does not need to be stored in such a way.
I would like to use a datatable or datalist or something to that sort.
Oh and I would like the visitor to be able to click on a name in the table and edit the data using the form controls not in the datalist or datatable itself.
I have implemented my own custom MembershipProvider with a custom data store. No problems so far. I would like for people to login using their email instead of a username. Because I have my own data store, this is not a major issue, I can just pass the email as the username for the MembershipProvider.
My question is, how do I store additional custom user data along in the FormsAuthenticationTicket? I want to store a couple of things that will never change, such as their UserId, First/Last Name and Country. I started looking into creating FormsAuthenticationTicket with the UserData, but quickly got confused. How do I store multiple things into this UserData, and how do I easily read this data back on every single ASP.NET MVC2 page. I found many samples, none that really seemed that great in terms of MVC2. There has to be a simple way to do this.
It would make no sense to read the UserId, First/Last Name and the Country from a database on each and every request because it would never change. Plus, while I want the user to login using their email, I'd want to store their UserId in the auth cookie so that it can be used in nearly every user related database query rather than the email (because in all the tables, the user data is stored along with the UserId - not the email because technically the email could be changed - I already figured that stuff out when it comes to the MembershipProvider).
What is the best practices for storing additional user data like this in ASP.NET MVC2?
I have a gridview control which gets data from database. One of the column is a checkbox and based on the value of the checkbox, I need to display 2 more columns. Currently I am having 2 issues:
1. I am able to achieve this when OnDataBound event gets triggered. Basically I am checking the row state and type and if it is in Normal mode I check the status of the checkbox and based on the status I am setting the style on the columns I want to hide (columns contain checkboxes). But for some reason, I am not able to hide the header. The GridView shows the header but the text boxes which are in the columns are hidden.
2. During Edit mode, I have attached a javascript to the checkbox and when the status of the checkbox changes, it hide/unhides the columns, again header cannot be made hidden. Also, if I use the Visible property of the header, I can make the header invisibly (only using the code behind) but when javascript is invoked on the checkbox during edit mode, it cannot find the controls as they are not visible and hence does not do anything. Since TemplateField does not support style property I can't even set the style["display"].
I need to store a large amount of data in user's session but I guess using Session Object is not the best way of doing that. Is there any other way around??? Remember I don't have small variables to store, I have large collections.
I have the follow code (i just listed the parts that might be the more important to understand my problem):
(Code Behind)
[Code].... (Page .ascx) [Code]....
The user control RatingControl shows the rating and the number of rates, the user control Pager is responsible for raising CurrentPageChanged when the page changes and BindData() is a function that binds data to the Datalist control.
When the page is loaded for the first time BindData() marked with ** is executed , thereafter i only want to load data when the event CurrenPageChanged raises.
So far so good, but the problem is when the CurrentPageChanged is raised and call the BindData() function, the user controls are not loaded properly, and things that i can't understand happen, like the user controls not receiving the properties initialized when they are loaded, but the other controls inside the Datalist like lblDescription are loaded correctly with their data.
Summarizing, the user controls are not loaded correctly in this particular case when the DataBind() is called by an event.
I already searched in the internet, and i read about page life cycle, user controls and i still didn't understand why this happens and how to fix it.
I have requirement that i have to accpted data from user in a gridview like control.That its row column heder contatin calender date and row header contain specfic taske ,one have to drag and drop user coreponding date to specfic taskfor eg: column header contatins dates like 1/04/20010 to 30/04/2010and row header contain specific task.one user drag and drop sepcfic entity correspond to sefic date and specific controlI have gone through site to find this type of control allow drag and drop and customize column and row header.
I'm creating a search box control including 1 textbox, 1 button.
What I want is textbox has the value "Type here..." initially, then if I put focus on that textbox, the value would disappear, and it show off when it lose focus like Google search box
I've done with that, but one problem arised, that is when i type new value to textbox and hit the button, for demonstration I add new Label and assign the value I just typed in to it but it didn't work. The value always is "Type here...".
I have a web form, and an "add vendor" button. Click the button, a modal dialog pops up (ajax:ModalPopupExtender). User selects one of two radio buttons which shows a data bound asp:View in an update panel - this view is data bound to a single row and must be populated by the user. However I also want to provide a cancel button which should close the modal dialog and reset the bound view.
However what is happening is that the ModalExtender closes, but when the "add vendor" button is presented again, it's still bound to the same data. Do I need to clear my data source? How so I reset the forms/views so that when the 'add vendor' button is clicked again the form is presented as it should be (IE the 2 select options, picking one re-binds the asp:View)?
What I need to be able to do is create a field in my gridview that contains a link that passes two variables. One is pulled from within the gridviews datasource and the other needs to be pulled from a textbox control outside the gridview.
From what I've read so far you cannot use a hyperlinkfield for this as the datanavigateurlfields cannot be set to pull from anything but the gridview's data source.
What I attempted to do was create a template field where in the itemtemplate I called:
I have one SqlDataSource control as DataSet with enable caching in one page aspx. Filtering is applied to this SqlDataSource control, so that the page always returns one record data.
My question: How to get the record data value from SqlDataSource control (one record data value) and store it as String variable?
I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
