i have this MDI parent and A Menu..... in a file menu, i have a log-in... when you click the log-in, the log-in system will show...my problem is when i click CANCEL then click it again it will be separated in the MDI PARENT and form another window..
here's a picture of it:
I am using modal window for my VB.NET program and I am trying to open this child modal window from another window, after I close the child modal window I am trying to refresh the parent but I am getting retry/cancel popup, I tried a lot of things to avoid but I can't get rid of this popup.
View 1 RepliesI have a popup aspx page that receives data from a parent page gridview Edit click. There is a great deal of parsing of data from parent page to pop up as the data is being translated in pop up, then sent back to parent page to be reassembled in the original text block before update.
When the popup passes the data back or is canceled, the parent page gridview is still in Edit mode.I would like to pass the Cancel or Update button click from the popup to the parent page gridview so it can complete the update or cancel event without asking the user to click the corresponding command button link from the gridview edit mode, to Update or Cancel.
UPDATE: There is also a jquery UIBlocker on the Parent page to prevent the user from returning to the page until the PopUp page processing has been completed. Below is the critical code:
PARENT Page:
function parentFunc(a) {
// Unblocks on return from popup page.
$.unblockUI({});

Had a problem with preventing the popup from reloading. So there is an if condition in the load event. A dynamic number of controls are built on the popup as literals. So the Page Init event and Page Load event fire on non Postback to rebuild the controls.
I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

Is there a better method for outputing the data, rather than having to concatinate all the elements into a string and then writing it? In the 'good old VB6' days a Print statement followed by each value and a separator would do the trick. I can't seem to find the appropriate override for the WriteLine method.

I am trying to write a vb2008 program that allows a user to select an airport from a combobox and then once the value has been selected it searches a comma separated text file once it has found the airport selected ( always the first column in the file) in the file it populates 8 other textboxes with the row data from the file. The idea is to select the airport and then it calls up the radio frequencies associated with the airport.I assume you have to call the data into an array and the search thorough the array until the combobox.selectedvalue = the value in the array, but i am unsure how to do this Ideally I would like to be able to the user to add data to the file thats why I used a combox, but I am having trouble trying to get the boxes to populate so first things first.

I've run into a bit of an issue. Sometimes a user starts a search, but doesn't want to wait for the search to finish because they thought of some change they want to make or because the search is taking too long.
How would I cancel a Search? I understand that I would have to run the Search on a separate Thread. Would I just abort the Thread? Or do I need to send SQL Server something to let it know that it can cancel the query?
