Hi All

I have implemented the Data Grid and Query Tool as one component. 

Functionality working for Data Grid:
  • Add/Update/Delete rows if object is editable.
  • Copy row 
  • Paste row
  • Refresh
  • Client Filter provided by the Backgrid.
  • Filter (User specified, By cell Selection, Exclude Selection
  • Add Limit to the query result
  • Download the data as CSV.
Todo's for the Data Grid:
  • Find a way to select backgrid cell when rows are not editable. If backgrid rows are not editable then Filter by selection and Exclude selection won't work 
Functionality working for Query Tool:
  • Execute sql query.
  • Execute the Highlighted sql.
  • Cancel the running query. 
  • Download the data as CSV
Todo's for the Query Tool: 
  • Open as SQL file.
  • Save to SQL file.
  • Auto Commit/ Rollback.
  • Output Panel should be resizable, so that user can
Attached is the patch file. Please review it and let me know the review comments if any.

Initial feedback based on my playing with it, and discussion with Ashesh:

- The View Data menu option should be on the Object menu, which should mirror the Context menu, except options should be disabled when not applicable instead of hidden.

- The Query Tool menu icon should be a glyphicon, to match the others.

- Please merge the functionality of the Refresh and Execute buttons into one button. We shouldn't have two buttons that do essentially the same thing.

- In Edit Grid mode, the History panel should log all queries (SELECTs, UPDATEs, DELETEs etc) as it would in the Query Tool.

- In Edit Grid mode, the Messages panel should display any messages from the most recent action  as it would in the Query Tool.

- Please add an SQL button. This should show/hide the SQL panel in *both* Query Tool and Edit Grid modes. In Edit Grid mode, that textbox should be read-only, but should display the SQL used (including any LIMIT/FILTER clauses)

- Please remove the border from the SQL box, such that it fills all available space.

- The Filter box should be in a modal overlay over the top of the SQL box/Results tabs as required. Those elements should be grayed whilst it is open.

- Please adjust the height of the Delete icon in the Edit Grid, such that it doesn't force the row height to be higher than it should be.

- If a field has been edited, but not saved, can we highlight it somehow? Maybe make the text dark blue?

- I think the names of the tabs are far too long. Can we change them to "Query 1", "Query 2" etc, then rename them to the filename if the user saves/loads a file?

- Ashesh and I discussed changing the History tab to be a grid, showing: Date/Time, Query (first line only), Rows affected, Runtime and Status, in a row per query executed. Ashesh suggested using a sub-form that can be expanded for each row, which could show the full query and error details (SQL State etc). New rows should be added to the top of the list.

- We should add an "Edit" button, which opens a drop-down menu. This would eventually include options as found on the Edit menu in the pgAdmin3 query tool, such as the "Clear SQL" option.

- Errors should be highlighted in the SQL box - a marker in the margin to note the line, and spellcheck-style underlining for the error word.

- Query results should have spaces converted to "&nbsp;", so that proper indenting is maintained (for example, on EXPLAIN queries).

- The "Add Row" button only works if you're on the last page of the resultset.

- Can the "Copy Row" button also populate the clipboard with CSV data for the row?

- In Edit mode, we need to be able to represent/set values to NULL.

- If I shutdown my pgAdmin server, then execute a query, I get no error, 0 rows displayed, and a message in the messages panel saying:

Total query runtime: 46 msec
3 rows retrieved.

If I restart the server, the query will execute correctly, however I should see appropriate messages when it's not running.

- The layout of the result tabs should be maintained if new Query Tool or Edit Grid tabs are opened.

Thanks!
