Forms Data Controls :: Datagrid View Control Producing Duplicate Data Results When Data Is Cached?
Oct 10, 2010
I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.
I have a detail view form consist of five fields my 1st field is jobnumber which is primary key i want to do that when user by mistake enter the duplicate jobnumber error occur that this is already used how can i do this ?
My page has Grid View & ObjectDataSource to bind data. In page preRender event and not post back I updating the Panel to display data. Suprisingly, it displays duplicate data. I check my stored procedure and it returns Rows correctly.
I have a page with 2 dropdown menus and 2 datagrids.
The datagrids get populated by a database based on a dropdown menu slection.
This page links to another page which in turn links back to the original. If the user leaves the first page and then returns back I want to keep the dropdown menus and datagrids populated.
I tried doing this with session variables but can't get the datagrids to stay populated ...
I have a dataGrid with ButtonColumns in my asp page and I would like to do the following to:
When a row is clicked, I want to be able to:
1 - Hide all rows and display only the clicked row dynamically/on the fly.
trying to loop thru the datagrid and display only the Row index passed by the OnITemComman - but unsure of how to do it.
2 - Extract the row values (all cells in the row) to use as parameters in a query.
Used many ways of many examples but i always get a blank value. Managed to get the button text in the class but i need the full row values not just the cell clicked.
i have loaded a datagrid with some data from access database using sql query. i have to read the data loaded in datagrid view the syntax to read data cell by cell usiing vb code.

We are adding tooltips to our ASP.NET MVC product, and we are getting the text from our database (technically, from a cached copy of the data). To do so, we created an Html Helper method:
The GetTooltipText method is in our BaseViewModel, and simply uses the passed in Id to fetch the tooltip from cache. Would this be considered a bad design? What other alternatives would we have?
i have a DatagridView which contains 5 columns. The Fifth Column can contain a number or a NULL value .
I need to edit the DataGrid it in such a way that the fifth column is hidden everytime.
And on a specific condition that if fifth column is not null , then display the value which is present in fifth column ,in a small subscript below the the corresponding element in first column .
currently I am doing a web application such that after user search for all the contracts,the contract id is a hyperlink in which user can click on it to view the results tied to it. There is 2 pages. One is for the search page and after searching results is populated below. The contract id in the grid view is a hyperlink so that when user clicks on it, they will go to another page and view the specific records tied to it. How shld I do this as I am creating this web application in 3-tier formatting.
This is the search.aspx:
[Code]....
This is the next page that will display the results tied to this particular ID:
I wish to use drop down menu(based on a table of my database) to update/insert data in a web form. The data is then fetch in to SQL table (Express).ow to do it ?
I have used the gridview in 3.5 framework to dispaly a report ,In grid view i have used an Image button as Edit,While clicking on that Edit Button The row data fields in gridview likename ,Address etc have to populate in the Textboxes (Not in the Grid view row I am giving entry form in the same page )all the textboxes must be in editable mode
I have a problem displaying data in a Grid View control when set a row to visible = false when a certain condition is true.
For example, if a DataRowData value has a condition set to true (custom in table) I set the visible property to false, so the data row will not be visible at run time.
The problem is that I'm using paging (10 rows per page) and if 8 of those rows fall into the true condition that won't show the row, that grid view page will only show two rows of data in page 1. The worst scenario is that if I go to page 2 of the grid view and all the rows (10) fall into the true condition, that grid view page will not show any data at all.
How can I show 10 rows of data at all times in a gridview? In other words, I would like to just show the visible rows at all times.
I have "Order" object with Columns Ticket,OTP and CustomerName etc.Intially on DataGrid, I'm binding Ticket only , when user clicks on "Column Chooser" button, another windows appears to pickup CustomerName,OTP columns to add specified column dynamically on Datagrid.

Public Class Order { publc void Order() { } public string Ticket { get { return this.strTicket; } set { this.strTicket = value; } } public string OtpNumber { get { return this.strOtpNumber; } set { this.strOtpNumber = value; } } public string CustomerName { get { return this.strCustomer; } set { this.strCustomer = value; } } } }
