Forms Data Controls :: Filtering Records Returned Versus Filtering At The Datasource
Mar 14, 2010 I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.
Forms Data Controls :: Filtering Gridview Rows From DropDownList Selection
Oct 30, 2010I'm trying to filter data based on the selected value from a drop down list and the according values of a local variable within a gridview_rowdatabound event. For example, if "In Arrears" is selected, the gridview should return all rows where the account balance is less than -100. So far, when I select a value from the dropdown list, it has no effect on the gridview. Here's the code I have:
If (DropDownList1.SelectedIndex = 0) Then
e.Row.Visible = True
ElseIf ((DropDownList1.SelectedIndex = 1)
And (AccountBalance <= -100))
Then
e.Row.Visible = False
ElseIf ((DropDownList1.SelectedIndex = 2)
And (AccountBalance > 100)
And (AccountBalance < -100))
Then
e.Row.Visible = False
End

Databases :: Oracleparameter From A Dropdownlist, No Selection Shows All Records?
Dec 10, 2010I am trying to find out the best method or practice to use a dropdownlist to feed my oracleparameter value. I currently have this working when I have a value selected in the dropdownlist. My issue is how to account for if the user leaves the dropdownlist empty. I want this to then return all data. My SQL has a where clause = to :HRM. I use a function that gets the text for my SQL from a text file. My dropdownlist box is populated via databind. I then inserted a item in my dropdown with 0 index with no text display and a value of "novalue" Below is my code to populate my dropdownlist
[Code]....
[Code]....
If I select an item and run my code it works great. This doesnt work with the no selection tho. Do I have to build the SQL dynamically with a check if the listbox is empty or not and then add the criteria? I was hoping there was a eailer way since I have many queries and parameters to build.
Here is part of my code using the oracleparameter.
[Code]....
I also saw a post about trying this, but I get an illegal error.
[Code]....
Not sure if I can replace the "AND HRM_FIELD = " text and use :HRM instead and then build the oracleparameter with an IIF to include the AND HRM_FIELD part.
VS 2010 - Presenting Large Number Of Records To User For Selection
Jul 24, 2014I have an ASP.net VB Web app I'm working on that has a requirement to provide a list of all our component part numbers to our engineers for selection into a custom Bill of Materials for reworking of an assembly. The list of part numbers is currently generated from a stored proc in our MRP systems/SQL database. The number of records being generated is slightly over 39K part numbers.
Although the SP only takes a few seconds to generate the data the web page is taking a couple of minutes to load, primarily because of the time to fill the control presenting the records to the engineers. I've bound the data to a combobox control to the engineer. They want to be able to type the first few characters of the part number if they know it and have the list filtered or be able to just scroll the data to find the part they are looking for.
I've read elsewhere that they may be a way to only populate a certain quantity of records rather than all 39K then filter based on the users actions. Unfortunately the discussions about doing this didn't provide any examples, references, etc.
My questions are these...
Is there a better way to handle this quantity of records than a stored proc and combobox? A
ny examples of a method to populate a certain number of records then filter based on user action?

Determining Row Of Grid From Templated Checkbox Selection With Autopostback?
Nov 2, 2010I have a databound grid with a templated field column that is a checkbox. When the user checks the checkbox, it will autopostback and update the row to indicate the box's check state.
My first attempt was to simply use the OnCheckedChanged method, but when this gets called, I have no way to know which row the checkbox came from. Thus, I don't know which row to update.
Can anyone suggest a method to determine which row the checkbox that fired the oncheckedchanged event came from? Or can you suggest a better way to achieve what I need to do?
I cannot bind the checkbox to the data column because I do not want the checkbox disabled in select mode, and do not wish to require the user to enter edit mode to change the value. I also need all rows to be editable. So, the best route seems to be in a templated column.

ADO.NET :: Searching For Records In Grid View?
Dec 22, 2010I have a webform that uses a gridview to display a list of records from a table. I also have a search box that allows the users to input their search text and next to it a Find button which will take whatever that is in the search box and match it against each record in the datbase using a simple select query.
Whenever this search is executed it takes up to 20 seconds to display the returned result in the grid. The search query uses the SQl Data connector class through SQL ADO.NET.
However, when I perform the same query in the SQL management studio the search takes a total of 2 seconds. I'm wondering why there is a big difference in timing. I know that the query searches the table of about 4,000 records. I read up on paging but I am new to this concept.
My code in ASP is:

Duplicate Records While Insertion Into Grid?
Mar 22, 2011I have a page which consists of a grid and add new button. When the user clicks add new button he gets several fields to be entered. So, when he clicks submit I usually write a query which checks if there is an entry already in the database. In this case, I succeeded. However, my task is to also show the records identical and let the user decide to proceed or not.SO, I am not sure of how to proceed with this one. So, can anyone just help me in giving an idea on how to proceed with this one?
View 1 RepliesHTML - Can Use The Grid View To Insert New Records
Jun 19, 2010Using the ASP.NET grid view. It displays 3 columns with 1 row for each, displaying an integer saved in the database. I would like to have a text input one for each column, so the user can add a new row of integers to the database. (The table only displays the last row updated, that part seems to be working OK)
Here is the code I have that displays data but without the input option I would like.
What is the way this is done in ASP.NET (3.5)? Are there more options in the control or do I need to manually bring in text input controls and give each one manual code to update the database?
