View 2 RepliesI have a detailsview, template as follows:
[Code]....
Codebehind: creating dataset, getting data from sql with adaptor and filling into dataset object, then setting detailsview's datasource.
I add 2 button to above template to able to edit data at asp page, and added event handlers:buttons:

My question is, what to do inside the detailsview update event function to able to edit and update data. My method can be wrong too.
on which all conditions we use dataset and datatable to bind data to a gridview?

The dataset is being populated, however when the page renders, the data nor the gridview are visible. I have tried using both IE and Firefox, binding / not binding the columns, AutoGenerateColumns Y / N with no success. As I am new to all of this ( VS2008, ASP.NET, C# ) I can't help but to think I am overlooking something basic.
I am using the following :

- MS Vista SP2
- Oracle XE ( local )
I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs
View 5 RepliesI have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
I need to bind a gridview with a dataset souce.but this dataset source is not loaded from database.its tables are loaded manually.

i'm currently doing a shopping website. The customer will have to selected the item they want to buy and it will appear in the detail view when they click add in the grid view. I need the info inside the detail view to be insert into a database call Orderlist.
i've try using INSERT INTO OrderList (ProductName, Price,) VALUES (@ProductName, @Price) but it don't seems to work.
Was it because i can't insert it like this as it is detailview? This method can work if is Textbox instead of detailview.

View 4 RepliesI have a tricky situation that I just cannot seem to figure out. I'm using ASP.NET 4.0. I have two databases (let's call them Northwind and MyDatabase for simplicity). I cannot modify the data in Northwind, but once I save a copy to MyDatabase, I can change it.
I have a GridView that shows all the tests associated with a patient. I first populate the GridView, retrieving all the tests in Northwind.Test that are associated to a PatientID. On a button click event, I need to: Create a new Patient record in MyDatabase.Patient (I've got this part done already).Use that newly created PatientID and INSERT all of the rows from the GridView intoMyDatabase.Test.
I have the PatientID available, I just don't know how to retrieve the data from the GridView.(Ideally) I would like to then be able to load that patient record in the future from MyDatabase and be able to UPDATE the tests in the GridView to MyDatabase.Test. I can load the tests into the GridView no problem. But I have no idea how I would save that data to a different datasource. Should I even be using a GridView, or something else?

I am trying to return a dataset. I must be doing something wrong. The returned dataset in this sample code indicates there is a datatable, Users, but there are no datarows. What am I doing wrong? This example is only using the rows.count, but of course I really need to use the whole datatable as the datasource for a gridview.
[Code]....
Public Function getmyds() As DataSet
Dim dsUser1 As DataSet = New DataSet()
Dim tbUser1 As DataTable = dsUser1.Tables.Add("Users")
tbUser1.Columns.Add("UserName")
tbUser1.Columns.Add("Days Remaining")
tbUser1.Columns.Add("UserAccountControl")
Dim rwDefaultUser1 As DataRow = tbUser1.NewRow()
rwDefaultUser1("UserName") = "John Smith"
rwDefaultUser1("Days remaining") = 100
rwDefaultUser1("userAccountControl") = "Enabled"
Return dsUser1
End Function
i am fetching data in a dataset.now i m trying to modify the contents using :
For Each row As DataRow In ds.Tables(0).Rows
If row.Item(7) = False Then
ds.Tables(0).Rows.Item(6) = "`/abc/xx/" & row.Item(0)
End If
next
but, this gives me error saying roperty 'item' is read only.
I need to know how to display a single row(or particular row)from dataset and display into gridview... i tried by using some codes, like the following, If strCourseLevelId <> "" Then Dim ds2 As DataSet Dim currentbundlenid As Int16 Dim prevbundleid As Int16 = "0" Dim bundlenos As Int16 = "0" Dim bundlecontent As Bundledata = New Bundledata ds2 = bundlecontent.GetBundleData(strCourseLevelId) If ds2.Tables.Count = 1 Then If ds2.Tables(0).Rows.Count > 0 Then With ds2.Tables(0) Dim strCnt As Int16 For strCnt = 0 To .Rows.Count - 1 With .Rows(strCnt) currentbundlenid = .Item("Bundleid") If currentbundlenid <> prevbundleid Then bundlenos = bundlenos + 1 End If If bundlenos = "1" Then GridView1.DataSource = ds2 GridView1.DataBind() ElseIf bundlenos = "2" Then GridView2.DataSource = ds2 GridView2.DataBind() ElseIf bundlenos = "3" Then GridView3.DataSource = ds2 GridView3.DataBind() End If prevbundleid = .Item("Bundleid") 'next write the main page content End With Next End With End If End If.
