using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;

gvMolecules.DataBind(); } }
catch (OracleException oe) {
Console.WriteLine("ERROR : " + oe.Message); }
finally { cmd.Dispose(); } } } }

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 :
- VS 2008
- MS Vista SP2
- Oracle XE ( local )

Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?

Nov 19, 2010

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).

ASPX CODE

[Code].... C#

When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it

Forms Data Controls :: Display A One Row Gridview When Gridview Is Bound To Empty Dataset

Jan 13, 2010

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

Forms Data Controls :: Binding DataSet And GridView, Apply Bulk Rows Edit And Update On GridView

Dec 10, 2010

I 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.

Nov 16, 2010

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.

Forms Data Controls :: How To Insert GridView Data Into Another Table

Oct 21, 2010

I 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?

Forms Data Controls :: Return Dataset As Datasource For Gridview

Dec 5, 2010

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
