View 4 RepliesI'm trying make FormView insert a new row into a database table via a stored procedure.My code runs without error but nothing appears in the database table.

Here's what I'm trying to do....
I have some information in a simple product database displaying in a gridview table. One of the columns is a row of checkboxes indicating whether the item has been discontinued or not. When the row gets updated, it needs to update the checkbox value in the database.
1. It needs to be disabled until the row is getting edited.
2. Send the string value of 0 or 1 to the database when the row is updated.
Here's the code for the sql datasource and the gridview part in question...
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:sqlDataMaster %>"
ProviderName="<%$ ConnectionStrings:sqlDataMaster.ProviderName %>"
SelectCommand="SELECT ID, ProductName, ListPrice, Discontinued FROM Products"

I am trying to set up a server on my own pc to test programs i am making, however i keep running into an issue with Access databases saying that it's not registered on my local machine or something like that. So i was thinking of trying MySql instead, but i cant figure out how to set up a database to run on my pc. I have done it using MySql Workbench before to connect to a database set up on my schools server, but that was an already set up database that they created for each student. I want to know how to set one up on my own pc. how to set this up? I tried the server administration section of MySql Workbench but it seems to ask for an existing database already.

View 1 RepliesWhy 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?

Using SQL and C#. I have a gridview with a template field. I need to modify the some items in the gridview when the user selects a given record and store the values back in the database. ProjectID is the unique key in the database.Gridview is done as a table. How can I do it? Here is my grid view implementation.

I have a gridview bound to a sqldatasource with editing enabled. If I click Edit, then either Cancel or Update, the update or cancel occurs and the Edit button reappears. However, I cannot then click the browser's back button without having the Update and Cancel buttons reappear. A second click of the back button takes me to a state where the Edit button shows again, *then* another back button click will take me to the referring page (the one before the one with the gridview on it.) IOW, it looks like the postbacks are cached. How can I prevent this and have the back button go straight to the referring page?

View 2 Replieshow can i create a backup table for my MySql base table.my base table name is FAB when ever user store the data into FAB table same records should be stored into back-up table automatically.how can i acheive this.i am really thank full to you if any one provide me solution.
View 3 RepliesI want to make sure I go about this in an efficient manner. I have a gridview. On the gridview, I have some columns that are read only values . These values go through calculations based on values in a database. The stored procedure takes information in the database, does some simply calculations (this value * that value / another value type of stuff) then returns a recordset as a datasource for the grid.
Other columns on the gridview have values the users can enter data. I want to be able to provide a recalculate button that will run calculations based on the entered values which will change the readonly values and then repopulate the gridview's read only values without going back to the database. This recalculate button is not the save to the database button. The save to the database button will take the values in the user entered columns and save them to the database. Then, the next time the grid is called, the page calls to the database and loads the grid.
So, what I'm looking to do is allows for recalculations on a gridview, a gridview with about 24 columns and about 1000 rows. My first thought is to create a class that reads the gridview and then applies the business rules, then updates the gridview some how. Or, maybe have a dataset table thats i read the value from the user inputs, then apply business rules and then bind the gridview to the dataset table. Do any of you have thoughts here, maybe have done something like this?

i am using date field in sql table , and in webforms , i am using a textbox relating to calendar extender toolkit , now if i won't select anydate from calendar , on debugging it shows "" but in database it shows 1900-01-01 . what's this going on ? i have also written on button click event :
protected void SubmitProject_OnServerClick(object sender, EventArgs e) {
if (StartDate.Text == "" || StartDate.Text == string.Empty) {
rec.Proj_StartDate = DBNull.Value.ToString();
} else {
rec.Proj_StartDate=Request.Form[StartDate.UniqueID];
}
}
also i id like this too :
protected void SubmitProject_OnServerClick(object sender, EventArgs e) {
if (StartDate.Text == "" || StartDate.Text == string.Empty) {
rec.Proj_StartDate = string.Empty;
} else {
rec.Proj_StartDate=Request.Form[StartDate.UniqueID];
}
}
but nothing happened , it still shows 1900-01-01 in database.
I have an excel file which gets updated every 10 seconds through an automated process. I need excel data to be updated in MY-SQL database which is located on a remote server.
How do I do that?
I have thought of following option:
1) Every 11 seconds, an Excel macro will run and will "Save as" excel as CSV file. (not sure whether this can be done by macro...just thinking)
2) This CSV file we will FTP to remote server using Windows Service.
3) On remote server, we will parse the csv file and Update MYSQL database.
Is this approach fine? Or do you have a better approach which requires less time to update the database?
