I have a DataTable that was built from dynamically created SQL, so I do not know the number of columns in the datatable.
How can I convert this datatable into an IList?
EDIT: I am then going to use this to send to a Telerik Grid on the page.
This is my GET Method to get my data from my DataTable
Private Function GetData() As PagedDataSource
' Declarations
Dim dt As New DataTable
Dim dr As DataRow
Dim pg As New PagedDataSource
' Add some columns
dt.Columns.Add("Column1")
dt.Columns.Add("Column2")
' Add some test data
For i As Integer = 0 To 10
dr = dt.NewRow
dr("Column1") = i
dr("Column2") = "Some Text " & (i * 5)
dt.Rows.Add(dr)
Next
' Add a DataView from the DataTable to the PagedDataSource
pg.DataSource = dt.DefaultView
' Return the DataTable
Return pg
End Function
It returns the DataTable as "pg"
What changes must I make to this GET method to get the records from a table in my database?
C# examples will also do but would be great to see a reply with my code and then the changes....
I have a textbox and a search button i trying to search file names in a database table and display them in a datatable...
private void GetSearchResults(string machineID, string searchFileName)
{
DataTable dt = new DataTable();
SqlConnection connection = new SqlConnection();
connection.ConnectionString = ConfigurationManager.ConnectionStrings["SumooHAgentDBConnectionString"].ConnectionString;
connection.Open();
SqlCommand sqlCmd = new SqlCommand("SELECT FileID, BuFileName FROM BackedUpFiles WHERE BuFileName Like '%@searchFileName%' AND MachineID=@machineID", connection);
SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd);
sqlCmd.Parameters.AddWithValue("@machineID", machineID);
sqlCmd.Parameters.AddWithValue("@searchFileName", searchFileName);

}
everything is working fine except that the searchFileName is not working in the query...
I tried putting just a value to check like
SELECT FileID, BuFileName FROM BackedUpFiles WHERE BuFileName Like '%b%' AND MachineID=@machineID

This is what i want to do with my website. I want to pull data from an access query and and load it into a listview table. The user will sort through the data on the website and remove the rows she doesn't want. After the user is done, they will click a send button that will email the data to the appropriate party.I have read the access query data into a data table. I have the list view table built, but I am unsure how bind the data table into the listview table. Is this the best route to go? Will binding the datatable to the listview table allow the user to delete rows out of the datatable?

I'm currently switching over to ASP.NET MVC and have ran into a problem. I have a list of items (e.g. a list of names) that I would like to display in a table. I would like to display it down a column, before starting onto next column.
I have tried a nested for loops for mark up of <tr/> and <td/>, and am getting undesired results.
I have 3 tables(Roles,Actions and RoleActionLinks). Roles table has few columns(RoleID,RoleName,Desc). Actions table has few colums(ActionID,ActionName,Desc). In RoleActionLink is created for store the association between Roles and Actions and this table has the columns such as RoleID,ActionID When I created the data model(edmx). it shows only Role and Action as entity. i did not find RoleActionLink table. but even there is no direct relation between Roles and Actions table, both tables are automatically related using RoleActionLink table. When i create the new Action, a action record should be populated in Action table(this is works fine). At the same time, i need to populate record in RoleActionLinks table. But i dont have the entity to populate.
View 1 Replies new developer here. I'm trying to populate a ASP table dynamically. This is what I'm trying to do.I have table with 1 row and 4 cells. I want to import information from a text file into the various cells. Each line of the text file is what I want to go into each cell.
For example if the text file reads:
Date
Time
Path
User
I want each line to go into each cell. Is this possible, or will I need to create a SQL Server table and read from that?
I want to populate a gridview with table data from SQL. I tried just returning my SqlDataReader object and using it as my datasource, but I am getting errors that the reader has been closed. I wanted to convert this to a DataSet and just return a dataset, but I couldn't find an easy way to convert the row data to a dataset. I've also read that DataSets are dead in .NET 3.5/4.0, is this true? Here's my Data Layer method. It would be awesome if I could return something useable as a datasource:
public SqlDataReader GetSites()
{
SqlConnection sqlCon = null;
