Forms Data Controls :: Gridview Save Existing Data When Adding Rows Via Arraylist?

Jan 19, 2010 01:48 AM

I have a gridview that contains template fields with textboxes that is used to look up inventory items. The page loads using an arraylist to display a gridview control with a predetermined number of rows. There is also drop down control that allows the user to add additional rows to the gridview if needed.

Currently when a user has already entered some data if you use the drop down to add more empty rows all the original entrys are removed. I want to save the original data and then add empty rows at the end.


Private Sub LoadDataGrid(ByVal numberOfRows As Integer)
Dim Counter As Integer
Dim GridList As New ArrayList
For Counter = 0 To numberOfRows
GridList.Add(New LibVB.Form2VB(Counter))
gvEnterParts.DataSource = GridList
End Sub

I'm lost, kind of a newbie to .net, have been working on this for 2 days! d.

Forms Data Controls :: Gridview Not Displaying The Datatable?

I had an issue trying to use autogeneratecolumns so since I know what columns to expect I Bounded them. Problem is after I assign the datatable to the gridview and then bind it I do not see it on my page. I know the datatable is full because I visualized it in VS2008. Code below.


After a user would select some data it will build a query for data that should go into the gridview. Here is the query in the code behind (this is in the Button Click protected void)

Forms Data Controls :: Displaying Gridview Containing DropDownLists?

Oct 15, 2010 10:15 AM

On one of my pages I display a Gridview. This contains a list of questions generated by a SQLDataSource, with a dropdownlist on each row containing the answers for that question. The answer values can be different depending on the question, so I populate them in the RowDataBound event for the gridview, using question information.

As the list of questions is longer than the page I have placed the gridview within a Div which allows me to use scrollbars to navigate the gridview. I also use some methods to preserve the location of the last question answered - so that on answering a question, the gridview does not reset to show the first part of the gridview.

This works fine for IE7, which is what I have been using for the development, and which part of my customer base uses. However, the other part of my customer base uses IE6, which causes a problem.

When an IE6 user attempts to answer some questions, they run into issues. Should they scroll down the gridview, when they select a value from a dropdownlist (Effectively, when they answer a question), there is a postback and all of the visible (i.e. onscreen) dropdownlists appear to be cleared. However, on mousing over any of the dropdownlists, their value is then shown. On using either the scrollbar, or on using the mousewheel to scroll the gridview, all the dropdownlists are 'refreshed' and their values are shown.

At no point does the application appear to lose the data, it is just not showing it until there is a mouseover or the gridview is refreshed. Another odd aspect of this is that this does not apply to the first 5 rows of the Gridview. Any of these can be altered without there being this display issue. Should the gridview be scrolled enough to show some of the first 5 rows and some subsequent rows, only the subsequent rows will have this display issue.

I have tried various things to correct this - originally I called my retrievescrollposition method on the SelectedIndexChanged event of the dropdownlist, but have since moved it to Page_Load as the Else branch of if (!IsPostBack). I tried rebinding the DropDownlist in the SelectedIndexChanged event, but this only helped with the Question I was answering - the display of any other onscreen questions was still affected.

Forms Data Controls :: Displaying Real Time Data (GridView)?

Mar 24, 2010 10:39 PM

I have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:

1. Load the GridView and refresh the contents every minute. (60 second intervals)

2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.

3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.

Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.

Forms Data Controls :: Gridview Edit Displaying New Web Page

I searched google for anybody who had a similar problem and can't find one. Does anybody know of a way to keep the gridview edit from creating a new window. I have no events in the gridview.

Forms Data Controls :: Sorted Gridview Not Displaying All Rows?

May 18, 2010 04:01 AM

I see from google that this is a common problem. I have a SQL server database that contains 26 rows of data. Two columns, the first is PK and an identity column (keys numbered 1 to 26) and the second column is a text field (nchar(10)) containing a letter of the alphabet (A..Z). The letters were inserted randomly to simulate sql being unsorted by default. I have a query that returns all of the data ordered by the letter column ascending. If I execute the query in sql server I get 26 rows orderd A..Z.

I have a gridview that is set up for paging (page size = 15) and sorting. When sorting is disabled, all data is correctly displayed on the gridview, 15 rows on the first page, 11 rows on the second page.

If I enable sorting, I get 15 rows on the first page and 11 rows on the second page, however on closer examination I find two letters missing and two letters duplicated on both pages. If I navigate to page two, then back to page 1 I find that the data is then shown correctly and the missing letters are back.

Has anyone struck this issue? I am thinking that the sort is not being initialized correctly, but am not sure where to look.
