You can use the tab control's change or after update event and use a select case statement to bind/unbind subforms according to the selected tab.<br />
<br />
But I would also recommend looking into using separate forms to handle some of the subforms, especially if your tabs/subforms contain a lot of bound controls. &nbsp;That really adds up in slowing your forms down.

<div>
<div class="content wysiwyg-content">
I have an access form with several sub-forms that takes too long to load.<br />
<br />
I have used the Page control so that each sub-form is on a separate page because the users don't need to see all the info in one go, but they do need quick access when required.<br />
<br />
Something I have tried is to make the sub-form control unbound and then use the Page's on_click event to set the Source Object value. &nbsp;However, clicking the page's tab doesn't seem to trigger the on_click event. &nbsp;The user has to click the middle of the page, which means an extra click is required.<br />
<br />
What other techniques can I use to speed-up the load?

Access Form takes too long to load

Microsoft Access is a rapid application development (RAD) relational database tool. Access can be used for both desktop and web-based applications, and uses VBA (Visual Basic for Applications) as its coding language.
