I have a datatable in MS SQL that has FirstName and LastName. In MS SQL I created a computed field called FullName that was ((rtrim([LastName])+', ')+rtrim([FirstName])) I created a DataSet and a Business Logic Layer. In my typed DataSet I saw FullName in the listing when I created it. I am able to use FullName in my webpage. I use it to populate a dropdownlist. However, now when I make changes to the Customer Table I am getting this error message (seen below)
Question: Should I have created the field FullName in my MS SQL Table or should I have left it alone and somehow just added a column to the DataSet and placed an expression in the FullName column? The column "FullName" cannot be modified because it is either a computed column or is the result of a UNION operator. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

The following query returns me the column name from the table in the database, and stores the column name in the grid. How can I change the column name in the grid using following code, if its possible?
DataSet p_dsInformixDataDs = new DataSet();
string cmd = "SELECT * FROM CUSTOMERS";
try
{
using (IfxDataAdapter da = new IfxDataAdapter(cmd, m_InformixDBConn))
{
da.Fill(p_dsInformixDataDs);
}
}
DataView myDataView = new DataView(m_dsInformixDataDs.Tables[0]);
if (myDataView .Count > 0)
{
GridView1.DataSource = m_dsInformixDataDs;
GridView1.DataBind();
}

I have a GridView that displays records from an Access database, and I want to filter the records using a selection from a drop-down list. The GridView populates on page load with all of the records. The drop-down list is populated at page load from a different table in the same database. The functionality of creating a new GridView filtered by the selection in the drop-down list is working. However, when a different page number is selected from the Pager of the GridView, the GridView "disappears," or isn't redrawn. The selected name remains selected in the drop-down list, but there are no GridView elements displayed. If I select another item in the drop-down list, I get a new GridView with the correct records, but then choosing a different page results in no GridView. I'm guessing there's something wrong with my OnPageIndexChanging for the GridView event code, but I'm not sure what. My code is below (C#, ASP.NET 2.0):
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;

I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.
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.

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 )

Anyway, what i am trying to do is display job vacancies by the result of a DropDownList value. Now each job name has a description. The problem i am having is i need to display the results in this logic:
Job nameJob descriptionJob location. But what is happening is the job description (body) is repeating the more vacancies there are. This is the page:
http://kidsunlimited.co.uk/vacancies_test_two.aspx
If you select Deputy Nursery Manager from the DropDown and hit the Search button you will see the results. After listing the first two locations the description is repeated and then the 3rd location is shown after this. This is my code:
