Forms Data Controls :: Update A Table In A Database?
Dec 16, 2010
Am trying to build a page that will display one record at a time. That is the user searches a records table and the page displays the record. Than when the user us done making any changes and clicks save, i want the page to update the records table. So far, i have the page displaying the search results, but the save functionality is not working. Actually after changing an entry and the save button is clicked, the records change are currently reverting back to the old data that they want to change it from. How do i go about updating the records in the database? Here is the code that I have been able to come up with so far.
I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
i got a problem to update my database which i bounded to datagrid. The problem is, i want to update my database only by clicking one update button at the bottom.. when the user click it, all the fields will be updated to database.
I'm working on a new project where I have the luxury of working from a Model to Database approach using Entity Framework 4.
The project I'm working on is taking an agile approach where different phases will be rolled out over time.
Will the Model First approach work in my case? I noticed when you "Generate Database from Model" it recreates the entire schema from scratch which will obviously wipe all the data that is in the db. I was hoping for a more "Update Database from Model" approach where the db would just be altered to reflect the changes rather than recreated
I have a gridview that is populated with rows of 4 columns.
2 of the columns are required as parameters and I do not want these displaying so I coded visible = False.
The other 2 columns, whilst visible, I coded readonly = True, as all that is required is for the user to select a particular row of data, and select it for edit.Then, the update should be pressed.
im tryin to do something without success. I have some SQL table with few columns (fileId(int), fileName, copies, color and finish), the page is build in a way, that the user upload few files (the files uploads to some folder, and the fileId and fileName are write to the above SQL table - so the other columns (copies, color, finish) are stay blank - which is OK!!!) after he finished uploading the files he can see the files names in GridView and in that grid view i put some textbox for copies, and 2 DDL for color and comments. I need to update the rows with the new data after the user click some button (the all rows) this is the code:
I have a detail view, i can edit the detail view but cannot update. i do it at code behind, no data source was use. because i need to update multiple table at the same time when i click update on the detail view.
I am trying to looping thru a data table and update a column on each row. However after updating I am getting both before and after update records in the data table. Assuming there is only one column called "Qty" withing the data table and I want to double the value in the column. I use the following to perform updating but not getting my expected result.
I have a gridview that gathers data from two tables, an orders table and a products table. I have an OrderQuantity from the Orders table and a StockQuantity from the Products table and a button to process the order.I am trying to move through the GridView one line at the time, substract the OrderQuantity from the StockQuantity and update the Product table.
1. As per my knowledge we use dataadapters/dataset when we want to deal with the huge amount of column/data. Is there anyway that if I want to update one or two columns in a table without using dataadapter/dataset?
2. There is a way that without clicking a button we can get the data using objectdatasource, I mean to say that there is no vb.net data in the code behind then how to debug if there is not data in vb.net in code behind.
how to create the xy table like above? Currently i have able to create to insert row table read from databse which is Worker Name. My problem know is to show column name also read from data and not key in manually. Her's is myb sample codewhich is i have able to show Roa read from database.
I have a GridView with some data in it. Now when I click on the Header text of any of the columns of the GV, the Gridview gets sorted according to the data in that column; however the order in which the data is represented in the database table remains the same. So whenever I am selecting some row in the GridView for performing any action on that row, it selects some different row in the database table.
EG: Say in GridView I have columns A B C with some data and say the corrressponding table in the database which stores these values, has columns A1 B1 C1when I click THE HEADER "A" in the GridView the GridView gets sorted according the data in that column, however this change is not reflected in the table in the database.. it still shows the data in the same order as when entered at the beginning.
I am using button field in gridview after user clicking a button data in the row want to add in my database table. i am using a storedprocedure to fill a data in grid achieve . i didnt know how to add a row field in database .
I have an admin page in which I need to change the list whenever a user signs up on our web site.How can I put and event to MySql database so that whenever the count of a table row changes it refreshes my update panel for me to see the new user.
My gridview was working just fine until I converted the Officer Report collum to a templatefield so I could have a multiline text box. Now when I go into edit mode and press update, it doesn't update. I don't know what I am missing here?
