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

How to Authenticate Uploaded file format, size at the GWT client side?
Hello Friends
My Problem is that I want to Authenticate Uploaded
file format, size at the GWT client side, But I not having no Idea,
I did my first attempt to do so in this way.
1) By creating a method at the client side
public long getFileSize(String filename) {
File file = new File(filename);
if (!file.exists() || !file.isFile()) {
System.out.println("File doesn\'t exist");
return -1;
}
//Here we get the actual size
return file.length();
}
2) Call to the method...
long size =
getFileSize(textField.getName());
if(size>5242880)
{
MessageBox.alert("File Size
exceed Upload Limits");
System.out.println("Filesize in
bytes: " + size);
}
else
{
formPanel.getForm().submit(GWT.getModuleBaseURL()
+"FileUploadServlet", null, Connection.POST, "Saving Data...",
false);
}
*
But this is not working, I find the reason of this is that "GWT only
support Java.lang, java.lang package at client side."
Then Please tell me what i should do to authenticate the file size and
format at the client side before upload start.
I am waiting for response from my Respected group members .
