I am using the Login control on my login.aspx page to login to my /Members/Default.aspx page to display their current weight and their goal weight using the DetailsGrid. I have everything setup and I can log in and verify the user login name, but it only give one weight regardless of who logs in. Below is the SQL for the SQL Source on the DetailsGrid. I am new with this, Comparing the UserNames on aspnet_Users.UserName and memInfo.UserName should be able to extract that data, correct? Obviously I'm missing something. :)
SELECT memInfo.curWeight, memInfo.goalWeight FROM aspnet_Membership INNER JOIN aspnet_Users ON aspnet_Membership.UserId = aspnet_Users.UserId INNER JOIN memInfo ON aspnet_Membership.UserId = memInfo.UserId AND aspnet_Users.UserName = memInfo.UserName
I'm building an ASP.NET MVC 2 site where I'm currently implementing an OpenID sign-up form. Unfortunately, I'm foreseeing a possible security bug/vulnerability inside my architecture.
Here's how I want OpenID login to work:
User requests /Account/Login, Controller sends back OpenIDLogin View. User enters their OpenID into the View, then OpenID authorization takes place, and finally the OpenID is returned to the Controller.The Controller checks whether the OpenID is currently in use by a user in the system or not. If it is, the user is logged in to that account. If not, the registration process begins.
And now, the OpenID registration process:
The OpenID identifier, as well as any other information provided by the OpenID provider (such as email address or name), is put into my custom ViewModel and sent to my OpenIDRegistrationForm View.The RegistrationForm View stores the OpenID in a hidden field to make sure that it gets sent back to the Controller.The user fills in the RegistrationForm View and sends it back to the Controller.The Controller creates the user account and puts the OpenID into the database.
The bug that I see within my architecture is that a user could modify the hidden value in the RegistrationForm View. Thus, they could spoof their OpenID! I will make sure to add another round of checking to the final Registration Controller Action to make sure that the OpenID that is provided doesn't exist yet, but there is still a possibility for spoofing. Can my architecture be improved somehow? I don't want this to end badly...
One solution I'm considering is encrypting the OpenID before I send it to the View and then decrypting it when it reaches the Controller. Should I try this?
I need to display a table with various info (names, dates, serial numbers, notes). In addition, there is one field I need to be one of three specified values (Raise, Lower, Release). What view would be the best/easiest to implement which would let me add/edit/delete entries as well as provide a drop down option for the Raise, Lower, Release options?
I am building a page with databound list control. For each row I want to display piece of info retrieved from web service call. This could be time demanding so I want to render page first and retrieved additional info asynchronously and in parallel later on. Anyone has some tips how to make it? Just to have a more detailed picture it is a product list in e-shop which I want to render so customers can use it (go to product detail/add goods to shopping cart...) but meantime there will be a placeholder displaying info that informations are retrieving which after completion of call will be replaced by result data.
I having a data from database which display in form of link button at a repeater control.Nw i want to get the particular data from the repeater contorl and redirect it to its respective page to show its details.May i know how to do it?
I have a gridview on which there is a colume of image button for user to select a particular row. When a row is selected, a modal pop up appears for user to edit data and finally uers hit update button (within modal pop up). I expect to update the selected gridview row with info on modal pop up. My question is how do I get the row number within the Update_Click event.
I've been hunting for a solution to grab the radiobuttonlist when they answer that particular question. It varies for the number of questions, but only one displays at a time, but there could be a radiobuttolist or checkboxlist based on the question type. I was figuring I could do this easy in the row command of the gridview, but that hasn't worked out so well since I can't get the datarow for some reason.
I am making a page that can get some info from a DB from a gridview and then print it to a PDF file. But I am having problems with the background color. If I use this line of code
Code : cell.BackgroundColor = New Color(System.Drawing.ColorTranslator.FromHtml("#008000"))
Then i get this error : System.Drawing.Color' has no constructors
Then I get this error: Value of type 'System.Drawing.Color' cannot be converted to 'iTextSharp.text.BaseColor'.
My code is: (the error is underline)
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim cmd As New OleDbCommand() Dim myAdapter As New OleDbDataAdapter() Dim myDataSet As New DataSet() cmd.CommandType = CommandType.Text cmd.CommandText = "select CustomerID,City,Country from customers"
I have a gridview that has a dropdown on a template on the row. The user is wanting to change the value and update the record automatically. I know that when the value changes, I need to have the OnChange to trigger. I am not sure how to get the row so I can get the record ID so I can create a SQL statement to update this field.
Should I be using something other than the gridview?
I have two gridviews, where the first is databound to a sql table (but does not display the primary key info), and want to filter the data displayed on the second gridview by using the primary key info from the first gridview table, indicated by the selected row in the first gridview - how I could achieve this? its kind of like using the gridviews as a menu and sub menu display!
almost typical master-detail scenario except the 'detail' data I want to display below the gridview will be coming from both the table that is bound to the gridview (master) and a related table.
simplified example: tableMain with field1, field2, field3 bound to master gridview. I need to select a row from the master gridview and have a form display below with field4 and field5 from tableMain, as well as all fields of tableDetail where field1 of tableMain equals field1 of tableDetail.
Is this what a 'formview' control is for? or do I just arrange my own controls to accommodate the data? Would a formview work considering my source will be partially from both the main table and the detail table? This is one of the scenarios were I know I could come up with something using none of the databound controls (except the master gridview), but I want to use the controls provided when it makes sense to do so, and utilize their benefits etc...
I generate dynamic grids based on a count value returned from some DB tables. the code for it goes like this : I give and Id to each grid that is generated.
if (myDataList1.Count >= 1) { for (int i = 0; i < myDataList1.Count; i++) { //retrieving the exact i count from pageload ViewState.Add("newCount", i); //creating the dynamic grid with its corresponding gridview properties. grvDynamic = new GridView(); grvDynamic.ID = "GridView" + (i+3); grvDynamic.AutoGenerateColumns = false; grvDynamic.RowCreated += GridViewRowCreated; grvDynamic.RowDataBound += grvDynamic_RowDataBound; //adding bound field columns to retrieve data from stored proc BoundField metric = new BoundField(); metric.HeaderText = "Goal "; metric.DataField = "metric"; grvDynamic.Columns.Add(metric); BoundField mtd = new BoundField(); mtd.HeaderText = "MTD"; mtd.DataField = "value_MTD"; grvDynamic.Columns.Add(mtd); BoundField goal = new BoundField(); goal.HeaderText = "Tier Level Achieved"; goal.DataField = "value_goal"; goal.HeaderStyle.Width = Unit.Percentage(10); grvDynamic.Columns.Add(goal); BoundField you1 = new BoundField(); you1.HeaderText = "Month End"; you1.DataField = "firstLevel_you"; grvDynamic.Columns.Add(you1); BoundField you2 = new BoundField(); you2.HeaderText = "Month End"; you2.DataField = "secondLevel_you"; grvDynamic.Columns.Add(you2); ButtonField singleClick = new ButtonField(); singleClick.CommandName = "clickHyperlink"; singleClick.Visible = false; grvDynamic.Columns.Add(singleClick); BoundField metricId = new BoundField(); metricId.HeaderText = "Metric Id"; metricId.DataField = "metricID"; metricId.Visible = true; grvDynamic.Columns.Add(metricId); //binding the gridview to data. grvDynamic.DataSource = data; grvDynamic.DataBind(); grvDynamic.Columns[5].Visible = false; } }
protected void grvDynamic_RowDataBound(object sender, GridViewRowEventArgs e) { //this basically gets the metric Id's of rows with the ishyperlink flag set to 'Y'. I need to make these particular cells clickable var isClickable = (from md in myDataList3 where md.IsHyperLinkFlag == 'Y' &&
md.value_MTD != null select md.metricID).ToList(); if (e.Row.RowType == DataControlRowType.DataRow) { // Get reference to button field in the gridview. LinkButton _singleClickButton = (LinkButton)e.Row.Cells[5].Controls[0];
This code works perfectly fine , depending on the ishyperlink flag in the database...specific cells in the grid are made clickable and then redirected to page2.aspx My Issue: I need to capture which specific cell in which specific grid the user has clicked. store some information in sessions based on the cell clicked and use that information in page2.aspx.
i have a gridview binded with data when i hover mouse to row i want to display a image button to display date ,and when i click the button i want to display calender control for choose date, and next step after i choose date it will be must insert into database. and mean while a hidden label control will display and date shuld be display in it
After saving image in db how can we retrieve it in gridview like thumbnail size image and by clicking on image in gridview its open as preview. How can we do this in asp.net using c#.
If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs
[URL] .... In this I have a select option gridview property enable selection. i want when i click the select butoon the data of this come to the text box ... like if gridview row contain item --unit --cost
