ComboBox and selectedItem.value

[cwolcott]

I think I have a timing sequence issue. How do I select a comboBox item via selectedItem.value in code behind during a Page_Load? The combobox is assocaited with a store whose DataSource is a LinqDataSource.

Do I need a direct event on the comboBox or a delayed task?

Hi,

I would set up a Store's Load listener with Single="true" option.

I am trying to work on a simple example, but here is my problem.

I have the Combobox that is being loaded from a Store associated with a LinqDataSource. After that data is loaded I need to set the selectedItems.value in the code behind based on some requirements. Then there is a GridPanel that has a Store associated with a LinqDataSource. The GridPanel load needs to use the selected item from the combobox.

So I have a ordering process:

1) Make sure the Combobox data is load;
2) Set the combobox selecteditem based on a requirement; ** This is the issue
3) Finally have the GridPanel's store load based on the combobox setting;

All my other forms have only had one store or if there were more they were not assocaiated. I see that there is an AutoLoad function on the store, do I need to set it to false and perform everything in my page load?

Could you shed some light on these requirements?

Also please clarify is this not an option for you:

Not sure, because I've not got the requirement yet. Is there a single Store for both ComboBox and GridPanel?
