Retrieve information from DropDownList

[Shaitan00]

--Using [VS ASP.NET]--

Given a dropdown list box (ddlDevice) filled with a Struct objects [DeviceInfo] as follows:

 

struct DeviceInfo

{

public int nDevice_ID;

public string sDevice_Short;

public string sDevice_Address;

 

public DeviceInfo(int pnDevice_ID, string psDevice_Short, string psDevice_Address)

{

nDevice_ID = pnDevice_ID;

sDevice_Short = psDevice_Short;

sDevice_Address = psDevice_Address;

}

}

 

 

--- MAIN CODE ---

DeviceInfo diInfo = new DeviceInfo(1, "Device1", "Home");

ddlDevice.Items.Add(diInfo.ToString());

 

[code]

 

 

Now later on in my code I am trying to retrieve the INTEGER value (nDevice_ID) associated with the selected item in the DropDown Listbox.

However everytime I try I get casting errors (cannot cast string as DeviceInfo (.Selecteditem) or cannot cast list item as DeviceInfo (.SelectedValue))

 

I have tried like

int dev = ((DeviceInfo)ddlDevice.SelectedItem).nDevice_ID;

int dev = ((DeviceInfo)ddlDevice.SelectedValue).nDevice_ID;

 

ANy help would be appreciated.

Thanks,
