How to change the 'edit' button to 'Update'+'Cancel' button in Gridview

Hi all,

I'm using a commandField 'edit' button in a Gridview which I hope to be changed to a 'update' and a 'cancel' button when the 'edit' button is pushed. My codes are as follow.  My problem is that I don't know what codes should be added to make the change I mentioned to happen.

THanks a lot for your assistance.

You need to set the EditIndex and then re-bind your GridView to its DataSource something like this: 

Protected Sub GridView1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing
	GridView1.EditIndex = e.NewEditIndex
	GridView1.DataSource = ???
End Sub

Thanks, Ed

Keep this in the row editing event of the grid

Thank you very much ecbruck.. it works. I moved a small step forward and is now in the rowUpdating event after I press the 'update' button.

can you give me some hint on how to read in the (now updated row contents) from the gridview?  This should be good for me as I already know what goes further forward.

Thanks once again..

Assuming you place your primary key "ContactId" within the GridView.DataKeyNames property, you can retrieve your data like so: 

Protected Sub GV_Rec_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles GV_Rec.RowUpdating
	Dim row As GridViewRow = GV_Rec.Rows(e.RowIndex)
	Dim contactId As Integer = Convert.ToInt32(GridView1.DataKeys(row.RowIndex).Value)
	Dim txtFirstName As TextBox = TryCast(row.Cells(1).Controls(0), TextBox)
	Dim txtLastName As TextBox = TryCast(row.Cells(2).Controls(0), TextBox)

	If txtFirstName IsNot Nothing AndAlso txtLastName IsNot Nothing Then
		Dim firstName As String = txtFirstName.Text
		Dim lastName As String = txtLastName.Text
	End If
End Sub

Thanks, Ed

Cast from type ''''DBNull'''' to type ''''String'''' is not valid.
How do I avoid getting this error: Cast from type ''''DBNull'''' to type ''''String'''' is not valid. I am trying to get values from the database into a form for updating using a Datareader, SQL is set to allow nulls for certain fields as they are not required but the only way I can get the form to display is by adding a space in SQL. Is there another way around this? Check if it is equal to DBNull.Value first and if it is, don't do the cast.Stanley Tan theSpoke Blog Where in the code does it need to go?

table_info('','','','%') cannot return any types
I was recently confirming table_info special cases and discovered the case for getting table_types cannot work. table_info('','','','%') should return a list of table types but it returns a list of empty strings instead: my @types = $h->tables('', '', '', '%'); print "all types:\n", join("xxx\n", @types), "\n"; # should output something like: # "dbo" # "INFORMATION_SCHEMA" # "sys" # and actually outputs: xxx xxx It seems to be down to the following ...

'or' or 'union'
Hello I was just wondering, in general what is better to use, an 'or' clause in a select or a 'union' to join two selects together. Do both statements create work tables? Many thanks Alex I think OR will be better than union. because suppose u have 3 tables and using OR u can join table a and table b and table c so each table will have only one read. but using union you will join table a and table b and in another query of union u will use table (a or b) and table c so ur one read is more in union .
