Forms Data Controls :: Gridview Change One Field And Cause Change In Another?

Mar 7, 2011

I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"

I am using the following demo: [URL]

to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.

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?

Forms Data Controls :: Joining Multiple Tables To Show Results In A Gridview?

Mar 4, 2011

I have been trying to make this work for a while, but I have not been yet able to figure this put. I am using VS 2008 and mysql database. I wrote a query and checked to see if it works in database. It does.

I have a gridview, whose select command is that query. But for some reason, I just get all the rows from one table only. I rechecked my datasource and it is ok. I read on some discussions that it is NOT possible to have data from two tables in a gridview. Is that true? If that is not true, how can I have data from multiple tables in a gridview? Or any other web control for that matter.
