[CLOSED] ComboBox.SelectedItem.Value is null in DirectEvents Select

[canusr1]

Hi,

How to get the ComboBox.SelectedItem.Value in DirectEvents Select Method?
ComboBox.SelectedItem.Value is always null in Select event.
I want to display Name in GridPanel's FieldName col when the ComboBox Selected Item value is changed.

 <ext:GridPanel
            ID="GridPanel1"
            runat="server">

                                <ext:ModelField Name="Field_Name" Type="String" />

Hi @canusr1,

A Column's Editor is not rendered to

<form runat="server">

so, its value is not submitted automatically.

If needed you can send it as an extra parameter of the DirectEvent.

<Select OnEvent="ComboBox_Select">
    <ExtraParams>
        <ext:Parameter Name="value" Value="records[0].data[this.valueField]" Mode="Raw" />
    </ExtraParams>
</Select>

Hi Daniil,

Now I can get the ComboBox's selected value.
How to update this value in GridPanel's other column?
GridPanel is using different store.

Thanks

Did I not demonstrate it with the ExtraParams code snippet? If no, please clarify the requirement.

You should use a CellEditing's Edit listener.
