If someone can advice me the best practice pattern to handle this situation....
I am reading all windows events thru WMI and storing them in datareader and then binding datareader to repeater control....
Thnx

Hi,
I have a simple problem. All I need is a simple program that provides only tableName from Northwind Database.
What SQL Query should I write.
In the following code, I get DataSet object by providing sqlSatement and tableName. I need to get a new tableName from
Northwind database at every iteration and pass the tableName to this method.
/****************************************/
private DataSet ReturnDataSet(tableName)
{
DataSet dataSet = null;
string sqlStatement = "select * from " + tableName;
try
{
using (SqlConnection sqlConnection = new SqlConnection(connectionInfo))
using (SqlCommand sqlCommand = new SqlCommand(sqlStatement, sqlConnection))
{
SqlDataAdapter sqlDataAdapter = new SqlDataAdapter(sqlCommand);
dataSet = new DataSet();
sqlDataAdapter.Fill(dataSet, tableName);
}
}
catch
{
//Log the exception.
}
return dataSet;
}//End ReturnDataSet

Please bear with me if i am wrong. As per my understanding after reading your question, you need to know table names from database...
Select name from sysobjects where type='U'
If my understanding is incoorect, please post ur query again....Good luck
Thx

does anyone knows how can i leave everyother row in a gridview empty and be able to bind a label to it

Hello
I need an answer for my question.
Imagine a html table. When you loop through the last column of the table that column needs to be display in a row alone immediately after the row that shows all the other information for that id is bind.
It is possible to do this in a grid view
If you need something else to clarify this let me know
Thanks

You need a totals row or something like that ? You need to either add it to yuor data source as a row, or put in a seperate grid to display it.

OR.....
Add an item bind event handler to the grid, check for a footer row and then do your calculations and add to the footer row as labels

I’m developing a web application that uses SQL Server 2005 as its database.
In the SQL database I have two tables that have identical structures. The only difference in them is data contained in them. One holds Company Titles. The other one holds Department names used in the company.
The table schemas are:
tblTitle
TitleID Numeric Identity
Title VarChar(50)
Deleted Bit
tblDepartments
DeptID Numeric Identity
Department VarChar(25)
Deleted Bit
On my web application I have two identical web forms. The form I use for Departments has a SqlDataSource Control on it. The Page Load event is:
Protected Sub Page_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) _
Handles Me.Load
Dim strSelectSQL = "SELECT [Department], [DeptID] FROM tblDepartments WHERE [Deleted] = 0;"
SqlDataSource.ConnectionString = MRMFunctions.WebConfigConnString
SqlDataSource.SelectCommand = strSelectSQL
ListBox1.DataSourceID = DtaSource.ID.ToString
ListBox1.DataTextField() = "Department"
ListBox1.DataValueField() = "DeptID"
End Sub
The code is pretty straight forward.
1. Assign the SQL string to a variable.
2. Get the connection string from the web.config file.
3. Set the SqlDataSource control to the SQL string.
4. Bind the Listbox control to the SqlDataSource control.
5. Assign the ListBox.DataTextField to the “Department” field in the tblDepartments table.
6. Assign the ListBox.DataValueField to the “DeptID” field in the tblDepartments table.
When I select a Department from the list box and press the edit button it fires the ListBox1_SelectedIndexChanged event. The code is:
Protected Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
strID = ListBox1.SelectedValue
strName = ListBox1.SelectedItem.Text
txtID.Text = strID
txtName.Text = strName
End Sub
This code is straight forward as well. Take the ListBox.SelectedValue and place it in the strID variable. Take the Listbox.SelectedItem.Text and place it in the strName variable. Assign the txtID.Text box to strID and txtName.Text to strName.
When I step through the code the strID will contain the ID number of the selected item and the strName will contain the name of the department.
Now for the problem:
I’m trying to accomplish the same thing, but without having to place the SqlDataSource Control on the web form. This form is for company titles, and its Page_Load event is:
Protected Sub Page_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) _
Handles Me.Load
Dim dr As SqlDataReader
Dim cn As New SqlConnection
Dim cd As New SqlCommand
cn.ConnectionString = MRMFunctions.WebConfigConnString
cd.Connection = cn
cn.Open()
Dim strSelectSQL = "SELECT [TitleID], [Title] FROM tblTitles WHERE [Deleted] = 0;"
cd.CommandText = strSelectSQL
dr = cd.ExecuteReader
While (dr.Read)
ListBox1.DataTextField = dr("Title")
ListBox1.DataValueField = dr("TitleID")
ListBox1.Items.Add(dr("Title"))
End While
cn.Close()
End Sub
What I’m doing here is declaring a SQL data reader, a SQL Connection and a SQL Command.
1. I set the connection string by reading it from the Web.Config file.
2. I make the connection.
3. I open the connection.
4. I set the variable strSelectSQL equal to the select statement I’m using to return my data with.
5. I set the SqlCommand command text equal to the strSelectSQL variable.
6. I execute the datareader to get the data out of the database.
7. I loop through the data and assign the ListBox.DataTextField to the “Title” field inside the datareader, the Listbox.DataValueField to the “TitleID” field inside the datareader, and add the “Title” to the listbox.
Logically this should be the same as the Page_Load event in the Departments page, but it isn’t.
When I select a Title from the ListBox and press the edit button the ListBox1_SelectedIndexChanged event operates diffently. The code is simular to the ListBox1_SelectedIndexChanged event in the Departments form, but instead of the strID variable returning the ID number of the title selected. I get the Title name. The strName gets assigned the Title name like it should, but there is no ID number for it.
The only explanation I can come up with is the DataTextField and DataValueField behave differently when using a SqlDataSource control compaired to a datareader.
Can someone please tell me what I’m doing wrong?
I have a form that requires five data sources and I would rather only have to hit the database once to populate the controls and the again to update the database.
Thank you,
Quecumber256

The DataTextField and DataValueField are not used at all when you are not databinding. What you are doing in the code is adding strings to the Items collection. The overload of the Add method that takes a string creates a ListItem object for you with the same string for text and value. That is why you are gettings the title as value.
What you should do is to create a ListItem from the Title and TitleID values and add to the Items collection.
Also, you have forgotten to close the data reader when you are done with it.
Quecumber256 wrote: and assign the ListBox.DataTextField to the “Title” field inside the datareader, the Listbox.DataValueField to the “TitleID” field inside the datareader
No, you are not. You are setting the DataTextField to the value of Title field and setting the DataValueField to the value of the TitleID field. The reason that this does not result in an error, is that the properties are not used at all.

Can you show me an example of how to do this? I know I can concatenate the two fields together and place it in the list. However, I would like to just show the names in the list and have the ID number retrieved from something like the DataValueField.
Another Question:
Can I bind the ListBox control to the DataReader?
Example: ListBox1.DataSourceID = dr
Thank you,
