[CLOSED] How To Pass hidden value

[Zarzand]

Hello

I have a grid panel that when I do a Insert I would like to pass a hidden ID and Date fro my Handler. How is that possible to do it. When I do a Insert I able to create new ID but my database has 2 required fields that user doesn't input when on a Insert. Can anyone help on this.

Thank you

Hi Zarzand,

I apologize for new question but what problem place in your code?

If you need to add additional information for every new row that you can use next code

var rowIndex = #{GridPanel1}.addRecord();
var record = #{GridPanel1}.store.getAt(rowIndex);
record.data['param1'] = 'value1';

if you need to pass additional parameters to save handler the you can define WriteBaseParams of Store

[Zarzand]

Can you please give an example.

Thanks

How Can I Set a value from my combobox to my Insert handler?

<Coolite:ComboBox ID="cboNorth" CausesValidation="true" FieldLabel="OSID" Width="150" StoreID="dtaNorthOSID" TriggerAction="All" Mode="Local" EmptyText="Select OSID" DisplayField="OSID" ValueField="OSID" ForceSelection="true" runat="server" Select&#111;nfocus="True">
</Coolite:ComboBox>

My Grid Listner

<Listeners>
<Click Handler="var rowIndex = #{grdCenterTap1}.addRecord(); var record = #{grdCenterTap1}.store.getAt(rowIndex); record.data['GraphDate'] = 'what goes here' />
</Listeners>

[Vladimir]

Hi,

if you need to have selected value from combobox for each new row then you could use next

<Listeners>
<Click Handler="var rowIndex = #{grdCenterTap1}.addRecord(); var record = #{grdCenterTap1}.store.getAt(rowIndex); record.data['GraphDate'] = #{cboNorth}.getValue();>
</Listeners>
