View 3 RepliesI try to work with MYSql (because it's free) and I saw that the colums are different then when they are exployed in MS SQL?
Why is this? The most strange differents is that in MySQL there is no applicationId in the membership table.
This differents in tables cost me more time to do a export and import from MS SQL to MySQL.
I have a data connection to an existing MySQL database. The database has various tables. I am creating a new table, and want to set the ID field to be the primary key. I can not see a way of doing this inside Visual Studio. I saw one suggestion to right click on my ID field in either the Server Explorer or XSD and select Set As Primary Key (or something like that), but I don't have that option displayed.
View 4 RepliesI have a requirement that I need to read an excel sheet using asp.net/C# and insert all the records into mysql table.The excel sheet consists of around 2000 rows and 50 columns. Currently,upon reading the excel records ,I am inserting the records one by one using a prepare statement into mysql table.But its taking around 70 secs to do so because of the huge data.
I've also thought of creating a new datarow, assigning values to each cell,adding the resulting datarow to datatable and finally calling dataadapter.update(...).But it seems to be complex because I got around 50 columns and hence I'll have to assign 50 values to the datarow.
i am very new to the programming and also asp.net. i have an assignment to create a table on webpage the information is coming from mysql database.

i'm using ASP.NET + a MySql Db. I'm trying to configure a ListView so i've written:
<asp:SqlDataSource ID="dsDatiUtente" runat="server" ConnectionString="Server=12.28.136.29;Database=mydb;Uid=m111d1;Pwd=fake;Pooling=false;"
ProviderName="MySql.Data.MySqlClient"
SelectCommand="SELECT * FROM user WHERE idUser=@IdUser"
/>
At the beginning of my aspx page i've added
<%@ Import Namespace="MySql.Data.MySqlClient" %>
But if i click to the sqldatasource and click "Refresh Schema" i got this error:
"Unable to retrive schema.... Unable to find the requested .Net Framework data provider" For instance, i've installed it , but i've also uninstalled old version, then installed new versions. In my project i simple copy Mysql dll into "bin" folder, then add a reference to that dll. I'm not sure is the corrected way...
I need to have the "refreshed schema" to permit vs.net to build automatically my listview ... if i can't to "auto build" listview, i have to write all code by hand, and it is a too expensive work me :(

View 2 RepliesI have been trying to create a sql statement that uses a subquery to join 2 oracle tables to create a strongly typed table adapter. For example:
Select productName, (select categoryName from categories where categories.category_id = products.category_id) as Category from Products
The ASP .Net tutorial I am working through recommends using subqueries instead of joins for the insert, update and delete commands to be automatically generated by Visual Studio 2010. When I click Finish in the table adapter wizard I get the following error (I am using MySQL version 5.1 and the MySQL Data Connector 6.3.5)

Why does a very simple script which inserts 26,000 records into a mysql database (myisam, no transactions) take 13 seconds in the php implementation, and then 35-50 seconds using mono+mysql connector? I thought asp.net was faster than php? Could the problem be the mono mysql connector is "platform independent", so the performance just stinks? or does asp.net suffer more overhead than php when it comes to executing each query? Aren't there any native linux binaries for mysql connector for mono that may be faster?
View 1 RepliesI am passing the table name to the controller. The controller forms an ITable object from the database and passes it to the view.
ITable table = (ITable)energyDB.GetType().GetProperty(tableName).GetValue(energyDB,null);
Now my question is : 1. How do I display this ITable in a ListView?
2. Would it be a better idea to populate a ListView with the data from the table in the controller and then pass the ListView to the view?
int count = 0;
foreach (DataRow row in table) {
string []ar=Array.ConvertAll<object,string>(row.ItemArray,p=>p.ToString());
ListViewDataItem item = new ListViewDataItem(count,count);
count++;
item.DataItem = ar;
tableView.Items.Add(item);
}

I have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application.

View 8 Repliesmaking my own filter page for a gridview and have ran into. When the user clicks on the add filter button, I create a row in an ASP table displaying the filter. The filtering works correctly and adds the row to the table. But att the last cell is a button that is created when the row is added to delete the filter. For some reason the delete button will not fire the event ive created for it. Any suggestions? Code that creates the tablerow and button.
private void BindDtToTable()
{
// Get the DataTable from Session
DataTable dt = (DataTable)Session["MyDt"];
// Loop through the rows
foreach (DataRow dr in dt.Rows)

// Create a table row
TableRow tr = new TableRow();
tr.ID = dr["id"].ToString();

I am doing a project where I need to be able to pick a records from a dropdown list and then have the rest of the records in the database display below in a table.
I attached an image of what i have so far which is the dropdown box and the table of data, but whenever i pick another item from the dropdown box it doesnt update the data listed below.
I want to display the data in the format that is represented in the screenshot. All the data that is shown is retrieved from Sql Server-2005 Database. Which is the best option for such kind of data representation? I have read in the forums, from them I could not get a clear perspective. Some were suggesting listview others nested datagrid, some repeater control. which one would be a proper and accurate way to go forward ?? Along with some reasons (if possible). And I'm using visual studio 2008, .net Framework 3.5, asp.net with c# and I'm NOT using LINQ in my project and it is a web application. The same picture can also be found at [URL]
