Hi,

I have a DataGrid that have a dataset as a data source.
The dataset is being returned from a web service.

The code:

webservice.service1 srv = new webservice.service1();

DataSet ds = srv.GetDataSet();

Session["dataset"] = ds;
datagrid1.DataSource = Session["dataset"];
datagrid1.DataMember = "SomeTable";
datagrid1.DataBind();

When editing a row in the DataGrid the DataGrid is affected by the changes
but the DataSource remains the same as before the edit.

What is the problem ?

after setting the SelectedIndex, reload the DataSet again and bind it again to the datagrid.

When I do that, the DataGrid shows the old DataSet (before the edit)

What do you use to update the data in the database?

Stored Procedures?

Or is stating the DataSource method ApplyChanges() enough because of using other ways to communicate with the database ?

In other words. First update the data in the database before retrieving it again otherwise you are stuck with the original data.

I guess I wasnt clear enough, Ill try to describe the problem again.

The web service has two functions the first one retrives a DataSet and the second one gets DataSet
as a parameter and save it to the DataBase with DataAdapter.

After I get the DataSet from the web service I bind it to the DataGrid (as decribed In my first message)
when I make changes throgh the DataGrid I expect that the DataSet will change but it doesnt,
that's why its irrelevant to save it back in the DB at this stage.

Why does the DataSet doesn't change when I'm changing the DataGrid ?

It is very simple.

You are in disconnected state with the database. So after changing data in the gridview you have to change the data in the database. The webservice retrieves it data from the database. So after a change your webservice seems to run a type of reload data from the database.

After a change in a gridview you have to update the data in database.

your working order is:
Load data from database
Bind it to the grid
Edit a row
Update the data from the row in the database (You can use .SelectedValue property to see the DataKeyName and/or DataKeyValue. In that case you can update the row with the SelectedValue als key for the where)
After updating you load data again from the database

I dont want to change the DB every time I edit the DataGrid, I want to update the DB only after I press on "save" button.

The question is what I need to do so that when I edit the DataGrid the DataSet will be updated (without updating the DB yet, until I press the save button).

Convert a web application asp.net c# into a console app c# using visual studio 2008?

I do not think it would be wise to store your datatable in a session object. Would cost way too much memory.

Better to add a Safe button in each row of the gridview. After they press that safe button upload the data and reload.

Hi Guys,

I recently finished a project which i now need to, rewrite to a console app, allowing it to be linked to windows scheduler.

Is there anyway to convert a web app to a console app?

Or is it amatter of creating a new console app and breaking down the code and re writting it into the console app?

Any help feed back would be greatly appreciated.

Regards

DMC

Yes. However if you followed standard Object Oriented Design Principles and Best Practices there won't be any re-writing, there would just be adding the original source files containing all the code for the application behavior into the new console project.

So did you? Big Grin | :-D

I have a textbox inside a usercontrol that is part of a modal window. I would like to set the focus to that control once the modal window is displayed. I have tried calling the controls focus() method. I have also tried adding script. It is just not working.

this.mpe.Show();
        this.EmployeeNumber1.resetControl();
        //this.EmployeeNumber1.TextBoxEmployeeNumber.Focus(); it is NOT working
this.Page.ClientScript.RegisterClientScriptBlock(Page.GetType(), "money", "document.getElementById('" + this.EmployeeNumber1.TextBoxEmployeeNumber.ClientID + "').focus();", true);

Any Ideas?

Try to use
TextBoxEmployeeNumber.UniqueID
instead of
TextBoxEmployeeNumber.ClientID

Still didn't work. This issue appears to be this.

the output renders my javascript but the modalpopupscript comes after my script and therefore the focus is reset to something else.

<script language="javascript"> document.getElementById('ctl00$EmployeeNumber1$txtEmployeeNumber').focus(); </script>
<script type="text/javascript">
//<![CDATA[
(function() {var fn = function() {AjaxControlToolkit.ModalPopupBehavior.invokeViaServer('ctl00_mpe', true); Sys.Application.remove_load(fn);};Sys.Application.add_load(fn);})();Sys.Application.initialize();
Sys.Application.add_init(function() {
    $create(AjaxControlToolkit.ModalPopupBehavior, {"PopupControlID":"ctl00_ModalPanel","dynamicServicePath":"/TankBookWeb/tanklist.aspx","id":"ctl00_mpe"}, null, null, $get("ctl00_btnX"));
});
//]]>
</script>
