xBrowse edit dialog and navigation

[reds]

I want to include navigation prompts in my edit dialog
i.e. Top,Bottom,Skip

How do I update the record object to contain the details of the newly selected browse row.

Regards
Peter

Please try

Code: Select all  Expand view

XBROWSER "CUSTOMER.DBF" FASTEDIT
 

You can see the edit dialogs with navigation buttons and also when the dialog is saved, xbrowse is updated automatically

Nages, I think reds mean for the oldest test there was on samples folder FIVEDEMO.PRG where on edit dialog there are buttons
top bottom prev and next to scroll records having the edit dialog

[reds]

Yes the demo example that Silvio has given is what I want to acheive

I want to have my edit dialog be able to navigate through the records,so when I move through the
browse the record object gets updated to reflect the new browse record that has focus.

Very shortly I will post a generic sample.
May I know the FWH version you are using?

We recommend using Record object created by FW_Record class (also known as TDatarow class in all previous versions) for editing any table, whether DBF, TDatabase, ADO, Mariadb RowSet, Dophin Query, etc. You use exactly the same code for any datasource and the class takes care of navigation and saving data.

Usage:
1) Prepare a dialog similar to the above function MyDlgEdit( oRec ), using the record object.

For navigation and save buttons use the exact actions used in the sample, for all dialogs.

You can use the same code for a table of the same structure on any database.

2) Link this function to Browse with

Code: Select all  Expand view

oBrw:bEdit := { |oRec| Yourfunction (oRec ) }
 

3) For Add/Edit/Delete actions of Browse, please use the methods oBrw:EditSource( .t. ), oBrw:EditSource() and oBrw:Delete(). Always use these methods only. This provides the same functionality irrespective of the datasource.

[Silvio.Falconi]

Nages,
I compile it
then I press the first button "Add" and the exe make an error




change this line

DEFINE BUTTON OF oBar PROMPT "Add" ACTION oBrw:EditSource( .t. )

instead of

DEFINE BUTTON OF oBar PROMPT "Add" ACTION oBrw:EditSoure( .t. )

[Silvio.Falconi]

is it compatible with tdatabase ?

[nageswaragunupudi]

Thanks for the correction. I corrected the source code above.
The code for xbrowse and edit dialog is the same for TDatabase also.
You can link the edit dialog directly to the tdatabase object and need not link it with xbrowse.

This is the code for TDatabase. Please note that the same xbrowse and dialog code works without changes.

[Silvio.Falconi]

Thanks Nages,

for now I prefer to use tdatabase because in tdata there are many problems that I still can't solve: unfortunately I have two or three modules made with tdata that I have to convert to tdatabase. I want to ask you a question:

I'd like to open the client file from a simple function so that I can also load the indexes for example:

oCustomers: = OpenTData ("Customers", {"TAG01", "TAG02", "TAG03"})
oCustomers: SetOrder ("TAG01")
oCustomers: gotop ()


but i don't know how i did it with

Function OpenData (cDbf, aIdx)
LOCAL oDbf
Locals

oDbf: = TDatabase (): Open (nil, cDbf, "DBFCDX", .T.)

IF VALTYPE (aIdx) == "A"
FOR i: = 1 TO LEN (aIdx)
DBSETINDEX (aIdx [i])
NEXT
ENDIF

return oDbf


or perhaps not need open the indexes

[nageswaragunupudi]

When you are using DBFCDX, you need not open indexes separately. You need to do that for DBFNTX only.
If you open the DBF with DBFCDX all the index tags in the .cdx file are all automatically opened.

Just open the DBF and set order to any tag you want.
Use oDbf:SetOrder( "tagname" ) followed by oDbf:GoTop()

[Silvio.Falconi]

ok

on normal code I opened all files and then on each procedure I made

SELECT CU (CU AREA OF CUSTOMER)

now how I can make to not repeat the string each time tdatabase()......

[TimStone]

I use a a split dialog. In the upper half are all the edit fields, and in the lower half is the xbrowse. As the highlight bar is moved, the data for the edit fields is changed. It allows my clients the opportunity to see ALL data on a record, move quickly between records, edit instantly ( no popup delays ), and of course with indexed scrolling in the xbrowse, records are quickly found. (Open the image in a new window so you can see all the fields that are editable at once ). The coding behind this makes it work very quickly, and safely. I've used this display method dating back to the DOS coding in the 80's and 90's and it adapts quite well to Windows.

[Silvio.Falconi]

I wrong the message
