Zen Datagrid save to table

Primary tabs

Hello all,

I have created a simple Datagrid and using jsonSQLProvider with a SQL statement as the datasource. Please see below.

<jsonSQLProvider id="json" OnSubmitContent="SubmitContent"
sql="SELECT PatchClassName,Environment,ModuleName,ModuleClass,TargetConfig,BusinessRule,MessageSchemaCategory FROM ProjectInventory.TablePatchClass order by PatchClassName" />
 <dataGrid pageSize="20" id="dataGrid" pagingMode="client" controllerId="json" sortMode="client"
  selectMode="cells" >
 <columnDescriptor caption="ID" type="string" readOnly="false"/>
 <columnDescriptor caption="PatchClassName" type="string" readOnly="false"/>
 <columnDescriptor caption="Environment" type="string" readOnly="false"/>
 <columnDescriptor caption="ModuleName" type="string" readOnly="false"/>
 <columnDescriptor caption="ModuleClass" type="string" readOnly="false"/>
 <columnDescriptor caption="TargetConfig" type="string" readOnly="false"/>
 <columnDescriptor caption="BusinessRule" type="string" readOnly="false"/>
 <columnDescriptor caption="MessageSchemaCategory" type="string" readOnly="false" />
  </dataGrid>
.......

I can see the Datagrid in the webpage as well as the data but,

1) The cell value does not change on doubleclick.

2) i am able to modify the cell when i press "F2". But the data is not stored in the table.

How can i save the modified value in the table?

Thanks,

Jimmy.

Thank you very much  ! I appreciate your time. I will apply it to my code and validate.

Thank you very much  Vasiliy Bondar.

I tweaked the code as per my tables and fields and is working as expected. I appreciate your help.

So i was successful creating the datagrid and some combo box. Making some progress. But....Got another hurdle. Help will be appreciated.

I want the datagrid to reflect values based on the value i select in the Combobox.  How to pass value from the combobox to the

altJSONSQLProvider  parameter and reload the datagrid ?

My combobox defines below method on change.

onchange="zenPage.rowSelected(zenThis.getValue());"

<altJSONSQLProvider id="PatchClassJsonId" OnGetSQL="GetSQL" >
<parameter paramName="1" value="C"/>
</altJSONSQLProvider>

<dataGrid 

,......

</dataGrid>

Method GetSQL(ByRef pParm As %String, ByRef pSQL As %String, pCriteria As %ZEN.proxyObject, ByRef pPagingInfo As %String) As %Status
{
Set pParm= "zenPage.getComponentById('DataComboId').getValue()"

Set pSQL = "SELECT ID,PatchClassName,Environment,ModuleName,ModuleClass,TargetConfig,BusinessRule,MessageSchemaCategory FROM ProjectInventory.TablePatchClass where PatchClassName %STARTSWITH ? " 
    Quit $$$OK
}
 

Thank you..

Thank you very much  Vladimir .

This was very helpful. I used the ChangeQueryOnServer as a reference and my code is working good.
