ListGrid Filter Issue

[emimayank]

Hi,
We recently upgraded to Smart-GWT v12 from v5.1. However, for a ListGrid we're facing issues in the filter column- the filter is non-responsive to the initial key presses in lower-case, but works fine for key presses in the Upper Case. I also noticed that when typing texts in the filter column in lower-case when I press enter it picks up the filter which I don't need for the Uppercase letters. Can someone please help me with this issue?

Regards,
Mayank.

There's very little we can do with such a vague report.

Only thing we can guess: perhaps you've built your filtering logic so that it is case sensitive, and the previous version automatically uppercased all input characters, but this is no longer working?

If so, you need to look at the code that was attempting to uppercase inputs. It was probably done in an unsupported way which happened to work anyway, but shouldn't have, and no longer does.

We're not using any filtering logic, Data Fetch is happening through Filter Data.
Here is the field Definition

ListGridField newField = new ListGridField(attributeName, record.getAttribute("DisplayName"));
String promptStr = ClientStringUtil.isNullOrEmpty(toolTip) ? record.getAttribute("DisplayName") : toolTip;
newField.setPrompt(promptStr);
newField.setAlign(Alignment.LEFT);
newField.setCellAlign(Alignment.LEFT);
if (exportFormat != null)
{
                    newField.setExportFormat(exportFormat);
 }
newField.setShowGroupSummary(true);
newField.setShowGridSummary(false);

boolean visible = record.getAttribute("Visible") != null && "true".equals(record.getAttribute("Visible"));
newField.setHidden(!visible);

newField.setSummaryFunction(new SummaryFunction()
                        {
                            @Override
                            public Object getSummaryValue(Record[] records, ListGridField field)
                            {
                                // Use the value of the last tag request for the group
                                // summary header.
                                if (ClientStringUtil.isNullOrEmpty(records[0].getAttributeAsString(attributeName)))
                                {
                                    return "";
                                }
                                else
                                {
                                    if (field.getType() == ListGridFieldType.INTEGER)
                                    {
                                        return records[0].getAttributeAsInt(attributeName);
                                    }
                                    else if (field.getType() == ListGridFieldType.FLOAT)
                                    {
                                        return records[0].getAttributeAsDouble(attributeName);
                                    }
                                    else if (field.getType() == ListGridFieldType.DATE)
                                    {
                                        return records[0].getAttributeAsDate(attributeName);
                                    }
                                    else if (field.getType() == ListGridFieldType.DATETIME)
                                    {
                                        return records[0].getAttributeAsDate(attributeName);
                                    }
                                    else if (field.getType() == ListGridFieldType.BOOLEAN)
                                    {
                                        return records[0].getAttributeAsBoolean(attributeName);
                                    }

What do you mean by "non-responsive" - no fetch occurs?

One problem here is that you are inexplicably applying the criteria to the grid right after filtering has occurred. Why would you do that? That would generally wipe out any changes in criteria that occurred during the fetch, which could be your problem.
