I've got a grid view. I want it to say "you have nothing to show" if there are no details.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If GridView1.Rows.Count = 0 Then
[Code].....
However; it seems to be working backwards and showing the message when there is data to display in the gird view and continues to be a blank page when there is not data to display in the grid view.
I've tried a variety of combinations with the below IF statement below but no success.

When the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?
Friend Sub CloseAllForms()
CloseHelpForm(True)
CloseDiagForm()[code].....

I have a program that is using API's to send mouse events and keyboard events to another application that is running. I need to know how to tell if there are any messages left to process for that window after I have click on a button or moved to the next field. I need to know this so I don't send any more mouse or keyboard events until it has finishing processing everything in its message queue. An example is that I click out of the key field and the form has to go out and read a client record. This may take a second or two, so I need to wait until the form is ready for more input.

I have a couple of modal popups on my page that hold checkboxes. The checkboxes are different items that can be added to a specific product. Some products, however, have all of one type of item assigned to them. I need a way to show a message in the modal when the modal is empty.
I have tried using a Label inside the modal that says "All features are currently associated with this product." But the label leaves a space in the modal when it's visibility is set to hidden and that was annoying so I ditched that idea.
What is a good way to have a hidden message that shows up when the modal is empty?
<asp:LinkButton ID="FeatureButton" runat="server">Feature</asp:LinkButton>
<asp:Panel ID="FeaturePanel" runat="server" CssClass="modalPopup"
Style="display:none">

I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.

I'm having an issue with the startup of my build app with vb2010.Let me explain what the situation is at the moment.
I have a form and a splashscreen. I use the application events (startup event) to check if there is a network connection, if so the splashscreen will run and it will check if the database is available, if this is the case, it will copy the online database to the local ms access database.If the startup check of the network is false, it the user gets a message that there isn't any network available and the program will try to run normal, then when the user clicks the ok button of that message, it will check if the local database has any records. If so the splashscreen will run and the program starts normal (without copy the database, because there isn't any network available).The issue that I am having is, that when there isn't a network connection and the local database is empty, (I do get the message that the local database is empty), but the program still runs, while it should exit.Here is the code of the application event:
Protected Overrides Function OnInitialize(commandLineArgs As System.Collections.ObjectModel.ReadOnlyCollection(Of String)) As Boolean
Me.MinimumSplashScreenDisplayTime = 5000[code]......

I've created a form that plays some internet radio. The thing is the user wants an extra form for volume control that is docked to the side of the main form. This is no problem, i've made that, but im having some trouble making this form shown at the same time as the main form.In short what i want is that when you set focus on form1, form2 should also get in the foreground. Not focused, it should just follow form1

I have a message box pop up if a practice doesnt exist in my application. However, the user MUST select 'OK' on the message box to accept the message.
