1. Can I have two different controls with the same name in two different formviews on the same page?
I have text boxes named the same in a few different formviews on one web page.
2. How do I autopopulate the rest of these text boxes once a value is entered in the first text box. I want the same value that was entered in the first to be automatically entered into other fields in different formviews..(same page)
i am getting following error on gridview.databind() Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack , ThreadAbortException,it was working fine and suddenly getting error, i don't what's problem is?
I'm working on a project where I have to create a page that displays the "health" of a system. I run a query and display the results in a gridview with a red or green icon next to it. This works fine when the page is first loaded. My problem is that I have a thread that runs a query every 30 minutes and rebinds the gridview but the gridview never refreshes even though the data has changed. How do I get the gridview to display the new results? The databound event never fires a second time even though I can clearly see that I have received new data. I assume I am missing something simple but I just don't know what. What am I doing wrong?
So I have a GridView and several events that can be triggered (such as filtering and inserting a new record) to manipulate the GridView. I want to make sure that I'm not calling DataBind on Page_Load, especially since I might have to call it again when certain events fire. Is there a way I can make it so I only have to call DataBind once on the GridView after Page_Load and anything else has fired? Like some event that will absolutely fire last where I can put my DataBind?
The reason I need to do this is because the DataSource for the GridView is set programmatically from a DataView when the page is loaded, so DataBind needs to run every time. Just, hopefully, not multiple times each time...
I have a gridview positioning issue that may have been answered elsewhere, but I couldn't seem to find a similar post...
I have a webforms app containing a paged gridview (e.g., 200 records - 50 rows and 4 pages).
When the user clicks on a button in a specific row, another web page is launched to process that button click. When the user closes that page to return to the main gridview, the databind event is rerun and the page redisplays the gridview starting at the top. However, I want to have the previous position maintained (like an html bookmark), so that the grid will automatically be scrolled to the the previously clicked gridview page and item.
Setting attributes such as "MaintainScrollPositionOnPostback" do nothing in this case.
i'm opening a new window and passing on to it variables in a querystring, the values are loaded into a function that is filling my dataset and then filling my Gridview. after i press the button field in my grid to delete an item, the databind doesn't show the updated grid but remains the same. i've noticed that if i navigate back and refresh i see it correctly. in FF btw no problem.
I am have a page with a couple of dropdowns which serve as criteria for a select SPROC. Once a selection is made in a drop down a panel is shown which contains gridview whose rows have been returned by the select SPROC.If you close the panel and change the drop down selection and then redsplay your panel the data from your prior selection is still displayed in the gridview, unless you page to the next group of records.
I have spent most of my time writing ASP.Net web pages, using VS 2005. I am now developing some client function for Windows, so I'm relatively less expert in VB.In my Windows program I have defined a DataGridView and linked this to a data table (within a tableadaptor). Now I want to populate it: on a web page's code-behind I would write Gridview.databind(). What is the equivalent with a DataGridView.
I have a drop down menu that is populated on page load. Below that, I have a gridview that has a select parameter based on that drop down menu's value. I can't get the gridview to populate with data based on the drop down. If I fill in the parameter with a constant, the data pulls fine, but when I switch the parameter to a form parameter, it won't pull.
I have a very complex page with 11 formviews, 1 dropdownlist, and 11 sqlDataSources.I have several issues
Page: This page controls my website users and their info. There are 2 different users with 3 different permissions; users - 1 Primary(account Creator), and the rest; Permissions - View, Edit(Manage), Create/Delete(Author)
Each Formview controls one column in the table.
1st. After Permissions are read, the add, delete buttons are to be disabled if no permission. If the User selected is the PrimaryUser the delete button is disabled. On Page load, the delete button is enabled even though the displayed user is the Primary, when you select another user, then select the primary again, the delete button is disabled, but when you select another user the delete button is still disabled. This should not be!
2nd. I then added a check to see if there was one or more locations, and if there is only one, then disable the edit button that allows a user to assign a user to a specific location. example: if there are 3 locations, you may assign a user to that office location, but if there is only one location, there is no need. I try to disable the edit button in formview, but I get "object reference not set to instance" which is total cr#$ because the button is there in the form.
3rd. When a page loads and all of your sqlDataSources have a Select controlParameter that is determined by a DropDownList, how is the initial record determined other than it is the first record?No matter how I work my code, these issues do not work, and it is very frustrating and holding my project back. I have been working on thes for a week.
I am using a dataset for the first time and so far it is going quite well. The one thing that I have not found in tutorials though is how to add a select command to the gridview when i do gridview.databind()
The gridview is just a simple click and add at this point and my code looks like this:
I am new to Entity Framework and working my way through it little by little. I think I have it figured out on how to get data into and out of 1 table at a time now the challenge is 2 tables into a gridview. I have a user table that has a list of threads that a user can mark to track. Easy enough. Assign the userid number & threadid to a table with a push button while the user is logged in and viewing any of the posts that are on that thread. The new challange is to get only the posts that the user has marked to track. SQL easy. Entity not sure what to do.
If I make a view or stored procedure and add it to the database that would be an extra step. To join the 2 tables as in sql Select posts from posts where track.userid = @userid join track on post.userid=track.userid Seems Entity was made to avoid this type of thing. Than once the data is gathered I need to bind it to a gridview()
Basically, what I want to do is to get all my data in 1 statement and then pull data from that into a GridView. I already have the columns that I want displaying in the GridView, but now I want to insert a footer row in between the header row and all the datarows, that contains a couple columns that will be the same for every row in the GridView. So something along the lines of this:
I have a page with a gridview control that shows files that have been uploaded to our site. The name of the uploaded files, who uploaded them, and if they have been downloaded, etc are stored in a table. The gridview is bound to the table through a sqlDataSource control. I have a button column in the gridview that downloads the file associated with a row when the button is clicked. All that works well. I have a check box column that shows checked if a file has been downloaded. When the download button is pressed.
the file downloads and then a short routine is run to update the downloaded field in the uploaded files table to set the downloaded field to true. This is done through a command string. All this works. Here is the question. After the update is run I do a databind on the gridview to update it. The databind is run in the PageLoad event is the page is a postback. This does not cause the current row to show downloaded =true (checked). If I refresh the page in the browser then it displays correctly.
On my aspx page I use a popupmodalextender to show (and edit) some data that is contained in a gridview (gridview is on the same page). Popup works OK and also the editing of the data, but when I close the popup (from code behind) the data in the gridview is not refreshed.
Why doesn't databind() work until I refresh the page?
I need to display data returned from a sql query into a gridview. This is easy enough to accomplish by running the code below:
Dim command As New SqlCommand(sql, connection) command.CommandType = CommandType.Text connection.Open() Dim da As New SqlDataAdapter(command) Dim ds As New DataSet() da.Fill(ds) Me.grvDisplay.DataSource = ds Me.grvDisplay.DataBind()
My issue is that for one of the columns, before it gets bound to the gridview, I need to format the value. Basically, it returns a value like 7.21. Each number represents something, so I need determine what this and display the worded value. I tried to do a datareader (see below) before the binding and store that value into a session variable and display that session variable into the gridview, but it just displayed the same value over and over.
Dim dr As SqlDataReader = command.ExecuteReader() dr.Read() Dim RT As String = "" Dim VersionName As String = "" Select Case Left(Replace(Mid(dr("Version"), 2), ".", ""), 1) Case "1" RT = "Pre-Release" Case "2" RT = "Final Release" Case "3" RT = "Interim Release" End Select Session("VersionName") = Left(dr("Version"), 1) & " Data Base " & RT & " " & Replace(Right(dr("Version"), 1), "0", "") dr.Close()
