    [CLOSED] Mark template column as dirty

    I have a standard grid. When I want to set a cell to be dirty, I get the record and then call:
    record.set("columnToUpdate", "Text");
    this automatically updates the grid and flags it as "dirty"

    however, if I am using a TemplateColumn, it doesn't show the red dirty hash mark. I know that it is either Renderer or TemplateColumn but I assumed this would work.

    How can I make the red hash show dirty on TemplateColumn? I am not able to set it via renderer? need to do it in JS

    Thanks,
    /Z

    Hi @Z,

    The problem is that a TemplateColumn doesn't use a DataIndex and its Template might be quite arbitrary. So, I don't think there is a good way to track a dirty status.

    Please post the TemplateColumn's configuration. I will think what to do.

    See below
    /Z
                    <ext:TemplateColumn ColumnID="aaa" Header="aaa" Width="200" Editable="false" Locked="true" >
                    <Template ID="Template1" runat="server"> 
                        <Html>
                            <a href="javascript:changeStuff());"><img style="cursor:pointer;width:16px;height:16px;" src="/resources/images/32x32/icon.png" /></a> {aaa} 
                        </Html>
                    </Template>
                </ext:TemplateColumn>

    What about a Column's Renderer for that instead of a TemplateColumn? Then you probably get rid of the problem with a dirty flag.

    Maybe. Let me try the renderer now. What about this for a template solution?

    I will add this to the Html of the TemplateColumn. Then I can parameterize the &nbsp; with a {isDirty} value. Then I just set the record.set('isDirty', '&nbsp') and it will show. By default, it is blank so it doesn't. 

    <div class="x-grid3-dirty-cell" style="position:relative;top:-3px; left:-5px;height:5px; max-height:5px;z-index: 10;">&nbsp;</div>

    I just re-wrote it as a renderer and it worked fine. a little ugly on the JS side (lets of concatenation) but I just built 5 strings, joined them and it works great now.

    on a side note, the template trick works also to show dirty but it is not as clean a solution.

    Thanks,

    Well, probably there is a workaround to get it working. Maybe, your approach will work well for you.

    Though, with a Column's Renderer you should not have any problems at all.

    You could use String.format().
    String.format("Hello {0}! I am {1}.", "@Z", "Daniil");
