[CLOSED] Rendering Combobox dynamically in gridpanel

[iansriley]

Hi,

I have a requirement that I need render a combobox in a gridpanel dynamically depends on other column value.

Grid panel is

<ext:GridPanel ID="GridPanel2" runat="server" Title="" Frame="false" Scroll="Vertical"
    AutoScroll="true" Header="false">                                  
    <Store>
        <ext:Store ID="Store2" runat="server" GroupField="XX">
            <Model>
                <ext:Model ID="Model4" runat="server">
                    <Fields>
                        ........
                        <ext:ModelField Name="Frequency" Type="Int" />
                        <ext:ModelField Name="DefaultFrequency" Type="String" />
                    </Fields>
                </ext:Model>
            </Model>
        </ext:Store>
    </Store>
    <ColumnModel ID="ColumnModel2" runat="server">
        <Columns>
            ...........
            <ext:Column ID="Column7" runat="server" Text="DefaultFrequency" Hidden="true" DataIndex="DefaultFrequency" />
            <ext:ComponentColumn ID="ComponentColumn1" runat="server" Editor="true" DataIndex="Frequency"
                Text="Frequency">
                <Component>
                    <ext:ComboBox ID="cboFrequency" StoreID="storeFrequency" runat="server" EmptyText="Select" DisplayField="Type"
                        ValueField="Id">
                    </ext:ComboBox>
                </Component>
            </ext:ComponentColumn>                                           
        </Columns>
    </ColumnModel>
</ext:GridPanel>

combobox cboFrequency Store contain following data
Id Type
1 Daily
2 Weekly
3 Monthly
4 Quarterly
5 Yearly

Format of store is

<ext:Store ID="storeFrequency" runat="server">            <Model>
                <ext:Model ID="Model2" runat="server">
                    <Fields>
                        <ext:ModelField Name="Id" Type="Int">
                        </ext:ModelField>
                        <ext:ModelField Name="Type" Type="String">
                        </ext:ModelField>
                    </Fields>
                </ext:Model>
            </Model>
        </ext:Store>

If DefaultFrequency is "3,2,1" then combobox should bind respective items only to that combobox for that row

Please suggest me some solution on this requirement.

Thank you

Hi @iansriley,

You can configure a ComponentColumn's Component in a ComponentColumn's BeforeBind event handler.

There is an example of using a BeforeBind event.
