Lakshmi,
Can you provide all your code from your menuEvent?
If you debug your code, were executed this lines?
if (pVal.MenuUID == "275")
{
oForm = oApplication.SBO_Application.Forms.ActiveForm()
oGrid = oForm.Items.Item("5").Specific
Help.ShowHelp(oGrid, strHelpFilePath, HelpNavigator.TopicId, "2")
BubbleEvent = false
}
I attached to this answer all my code in VB.NET and C# version.
I hope that helps you.
Regards,
Diego
