GridPanel - control visibility of column by using another dataindex's value

[JD]

How do I set the visible property of the column "Quantity" by using the value from another column from the same store.

DataIndex="bitDiscontinued" within a girdpanel.

<ext:NumberField ID="txtQuantity" MaxValue="2000" AllowNegative="false" AllowDecimals="false"


MaxLength="4" 


<U>Visible="Want to use the DataIndex="bitDiscontinued" to control the hiding of this column"</U> 


runat="server" />

<ext:GridPanel runat="server" ID="GridPanel1" Height="400px" ClicksToEdit="0" Frame="true"


Border="true" StoreID="Products">


<ColumnModel ID="ColumnModel1" runat="server">


<Columns>


<ext:Column Header="ProductVersionId" DataIndex="atnProductVersionId" Sortable="true"


Hidden="true">


<Editor>


<ext:TextField ID="TextField12" runat="server" />


</Editor>


</ext:Column>


<ext:Column Header="Number" DataIndex="strProductVersionNumber" Sortable="true">


<Commands>


<ext:ImageCommand CommandName="Details" Icon="Information" Style="margin-left: 5px !important;" />


</Commands>


</ext:Column>


<ext:Column Header="Quantity" DataIndex="numQuantity">


<Editor>


<ext:NumberField ID="txtQuantity" MaxValue="2000" AllowNegative="false" AllowDecimals="false"


MaxLength="4" 


<U>Visible="Want to use the DataIndex of bitDiscontinued - How do I do this"</U>


runat="server" />


</Editor>


</ext:Column>

Hi,

If you want to prevent the editing of particular cell then use BeforeEdit listener

<BeforeEdit Handler="if(e.field == 'Quantity'){e.cancel = e.record.bitDiscontinued;}"/>

Thanks that solved the issue but ended up doing something like this to keep a quantity from being entered in.

<Listeners> 


<BeforeEdit Handler="#{txtQuantity}.setDisabled(!e.record.data.bitHideBackProductVersion); " />
