Forms Data Controls :: Programmaticallybinding Data In DetailsView TemplateField Linked To GridView

Feb 12, 2010

I have built a set of custom business objects that I have successfully bound to the GridView and DetailsView controls using the ObjectDataSource. I have been able to provide insert/update/delete functionality and all is working as expected. However, I am trying to wrap this functionality into a custom user control that allows the consumer to specify a table name and a list of column names and have it build this functionality on the fly without regard to the table structure (ie...available columns). I have been able to successfully get the GridView and DetailView to build the columns from code behind and I had all the CRUD working while using 2 panels to show/hide the GridView and DetailsView controls, but I wanted to add some AJAX ability to the control using Matt Berseth's modal popup example to make the interface slicker. The problem I am having is that the EditItemTemplate for the DetailsView control has to be specified in the code behind (because of the flexibile nature of the columns) and I can't figure out how to bind the data from code (rather than having the columns defined and bound in the markup). For all intensive purposes, I am trying to find the code behind counterpart to the following code snippet that binds the data to the textbox:

[Code]....

Forms Data Controls :: Load 'item' Data From Linked Table?

Feb 2, 2011

I have come from MS Access and am working through a couple of textbooks on ASP.NET 4. I am using the Gridview control connected to an SQL data source control.

As an exercise I am converting my simpliest MS Access page which is simple a form to request a new stock item in our engineering stores. I have a normalised table called [stock_requests] and part of this is a field calle [failure_mode]. This field is an integer and there is another table listing the possible values for this field.

This other table is called [failure_modes] and has two field:

[id] < the primary key

[mode] < the text to be displayed

In my main table [stock_requests] in the field [failure_mode] I store the [id] from the [failure_modes] table for the applicable record in the [failure_modes] table. So for example if someone wanted to select "Catastrophic" as the failure mode the [stock_requests].[failure_mode] field would be 1; if the user selected "Gradual" as the failure mode the [stock_requests].[failure_mode] field would be 2 etc.

Now, the gridview wants to display "1" or "2" but I want to display "gradual" or "catastrophic" without using views and all the headaches that brings. I have managed to sort out editting by using a templated field where I have a drop down list in this cell and I databind to a second SQL data source (imaginatively called SqlDataSource2).

what is the best method for displaying the text 'Catastophic' or 'Gradual' etc. when in normal mode (view mode)? Is it another templated field and what is the basic approach I should use? I reckon I should be able to work it out once someone points me in the right direction.

Forms Data Controls :: Gridview For All Tables?

Sep 30, 2010

I have a task to create grid view for 8 different tables. I am wondering if there is a better way to create those gridviews. The following features has to be in almost all 8 gridviews

1. Add / Edit / Delete / Sort
2. Some of the grid view has to contain a combo box when editing the row
3. A check box has to be in first column of the gridview
4. When editing the grid view, I need to have an edit form pop up
5. Confirm delete dialog box has to show before delete.It is not smart to create 8 grid views ( I am trying to avoid creating the grid manytimes)

Forms Data Controls :: Gridview Update With Related Tables

Nov 24, 2010

I have a problem in getting my gridview to update. The datasource gets its data from 2 related tables using the following select statement:

SELECT StudentSubject.StudentID, Students.[1stName], Students.Surname, Students.Grade, StudentSubject.Subject, StudentSubject.GradeOverall, StudentSubject.ReportYear, StudentSubject.ReportSession, StudentSubject.Criteria1Grade, StudentSubject.Criteria2Grade,
StudentSubject.Criteria3Grade, StudentSubject.Criteria4Grade, StudentSubject.Criteria5Grade, StudentSubject.Criteria6Grade, StudentSubject.Criteria7Grade, StudentSubject.Criteria8Grade, StudentSubject.Criteria9Grade, StudentSubject.Criteria10Grade, StudentSubject.Comment
FROM (Students INNER JOIN StudentSubject ON Students.StudentID = StudentSubject.StudentID)
WHERE (StudentSubject.Subject = ?) AND (StudentSubject.ReportYear = ?) AND (Students.Grade = ?) AND (StudentSubject.ReportSession = ?)

The ? stem from combo box controls which I use to filter the results So far so good!

However, when I try to update the data in just one of the tables, nothing happens, no error, just no update. The update statement I'm using is:

UPDATE StudentSubject SET GradeOverall = ?, Criteria1Grade = ?, Criteria8Grade = ?, Criteria7Grade = ?, Criteria6Grade = ?, Criteria5Grade = ?, Criteria4Grade = ?, Criteria3Grade = ?, Criteria2Grade = ?, Criteria9Grade = ?, Criteria10Grade = ?, Comment =?
WHERE (StudentID = ?) AND (Subject = ?) AND (ReportYear = ?) AND (ReportSession = ?)

I've tried this with a similar setup with just on table and it works fine.

<asp:AccessDataSource ID="DSGrid" runat="server"
DataFile="D:RW docsVisual Studio 2008WebSitesFellbach ReportsApp_DataReports - Copy.mdb"

Forms Data Controls :: Entity Framework Using 2 Tables Databind() To A Gridview?

Jun 16, 2010

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()

Forms Data Controls :: Build Gridview Dynamically - Multiple Tables?

Jun 29, 2010

I have a .NET 1 web app that is using a Oracle database, the web app has a page of table names that allows the users to select, there are 101 tables listed on the page. When the user clicks on a table name, it takes them to a page that shows user friendly column headers, the table data, etc. Is there a way to use one GridView to do this and show the user friendly column headers instead of creating 101 pages or 101 user controls and show that control based on the table passed into the page?

for example: the user clicks table 22, I want my gridview to look like this

Buyer's Name State City Zip Code Phone Number

if they click table 55 I want them to see this

Product Wholesale Price MSRP Sale Price On Sale (check box)

instead of showing the users

BuyersFullName BuyersState BuyersCity BuyersZipCode PhoneNumber, etc

and so I, I would like to use 1 gridview on one page if possible and build the grid on the "fly", We have the user friendly column headers in a table.

So my questions are:

is this possible, if so, what is the best approach in doing this

from a scalabilty level and maintenance level, would the 1 gridview be worth for all 101 (and growing tables), or would building a seperate user control for each table be better?
