Hi, I want block the edition of one specific cell. So the value can't be change by the final user.

I did use this code :

EditableCellStyle style = range.getCellStyleHelper().createCellStyle(range.getCellStyle()); style.setLocked(true); range.setCellStyle(style);

But it's not working ... And I don't know WHY ! No warning, no exception...

In fact any change on CellStyle don't apply... WHY ? My setCellValue that is make just after take effect...

And need a manual that is up to date... (Not some "this one is not updated, but you can look the new one that have nothing to say...")

Hello kolodz,

Did you try to protect sheet after set locked?

Here is a protect demo from zss essentials in ZSS 3.5.0 version:

protect.zul

<window hflex="1" vflex="1"
    apply="org.zkoss.zss.essential.ProtectionComposer">
    <hlayout hflex="1" vflex="1">
        <spreadsheet id="ss" hflex="1" vflex="1" showFormulabar="true" showContextMenu="true"
            showSheetbar="true" maxVisibleRows="100" maxVisibleColumns="40" 
            src="/WEB-INF/books/protection.xlsx" />
        <vlayout width="300px" vflex="1">
            <groupbox hflex="1" >
                <caption label="Protection" />
                <grid vflex="1" hflex="1">
                    <columns>
                        <column width="200px"/>
                        <column/>
                    </columns>
                    <rows>
                        <row>
                            Current Sheet Protection Status: 
                            <label id="status" style="font-weight:bold"/>
                        </row>
                        <row spans="2" align="right">
                            <button id="toggleProtection" label="Toggle Protection"/>
                        </row>
                        <row>
                            Current Cell Locked Status: 
                            <label id="lockStatus" style="font-weight:bold"/>
                        </row>
                        <row spans="2" align="right">
                            <button id="toggleLock" label="Toggle Lock"/>
                        </row>
                    </rows>
                </grid>
            </groupbox>
        </vlayout>
    </hlayout>
</window>
