update a gridview manually
In ASP.NET 2.0 and C# I have a page with a gridview and SqlDataSource.
In the beginning In SQLDatasource I had the commands for select and update.
I had to create the select manually with sql dataadapter and then bind it to the gridview because there was
aspecial query for it. so the selet command will not be from the sqldatasource. The question is if I can
still use the sqldatasource for the update command or I should also do it manually.
I so I would like to see an example for this.
thankYou

I created the sqldatasource with the updatecommand only, then in the code behind created the selectcommand
and put it together with
Sqldatasource1.SelectComma
at the beginning there is no data and only after a GO button is pushed the select is created and the gridview
has values. The problem now is that when I want to update a row, The data in the gridview disappear , I get an empty gridview and only after I push the Go button again I get the option of updating a line and everything comes
back.
What is the problem?

Do you want the gridview to bind on load? If so put the databind in page_load event.
As for losing all data, have you got viewstate enabled?

I don't what the gridview to bind on load. Only after push the GO button.
Then I give the gridview the sql datasource with a select command but it dissappear afterwords.
How do I enable the viewstate? Isn't in the default choice of a page?
Thanks

viewstate is a page and control property. You will see it in the property window of the gridview and datasource.
