Re: how to update database, when a row a deleted in the smartGwt ListGrid
You have to connect to your server (via RPC for example) and submit a
DELETE query where the row is equal to what was in the listGrid.

how to update database, when a row a deleted in the smartGwt ListGrid
Hello Friends...
Now i need your help..
I am working on SmartGwt Expendable Grid...I am using ListGrid Class
to generate grid.
i want to delete the row from the grid...and changes should reflect
into my database..Please provide me some idea to do that...
This is my code fragment...
ListGrid listGrid = new ListGrid() ;
listGrid.setShowRollOverCanvas(true);
listGrid.setWidth(800);
listGrid.setHeight(400);
listGrid.setAnimateRollOver(true);
listGrid.setCanExpandRecords(true);
listGrid.setAlternateRecordStyles(true);
listGrid.setShowAllRecords(true);
listGrid.setSelectionType(SelectionStyle.SIMPLE);
listGrid.setSelectionAppearance(SelectionAppearance.CHECKBOX);
listGrid.setExpansionMode(ExpansionMode.DETAIL_FIELD);
listGrid.setDetailField("report");
// on click the remove button i want to delete the selected row from
the database...
// using this method "removeSelectedData();" my selected record
deleted from the grid but not from the database.
removeButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event)
{
SC.say("Inside Remove Button");
listGrid.removeSelectedData();
}
});
NOTE:- I am directly fetching data from the database and set that
data into the DataSource. and this datasource is linked with the grid.
..
Now Please tell me how can i update my database when i delete selected
record from the SmartGwt List Grid .
I need Help...
Thanks
