Hide or show a text box based on another bookmark selection
First of all, I found this helpful, but not exactly what I need Windows Forms "On Select Tab" Event?
This only covers the changed selection event for the entire tab control, not each individual tab.
What I need to do is hide or show certain text boxes based on the page I selected. The example below, apart from the click event, does not work. ExpenseReport and ExpenseReview are my two tabs. Any help would be appreciated!
private void tpExpenseReport_Click(object sender, EventArgs e)
{
txtTripNo.Visible = true;
txtTripNo2.Visible = false;
}
private void tpExpenseReview_Click(object sender, EventArgs e)
{
txtTripNo.Visible = false;
txtTripNo2.Visible = true;
}

Use the TabControl SelectedIndexChanged event .
Assuming there are only two tabs. (If there are more, I would use a switch statement instead of if..else)
tabControl1.SelectedIndex_Changed(object sender, EventArgs e)
{
if(tabControl1.SelectedIndex == 0)
{
txtTripNo.Visible = true;
txtTripNo2.Visible = false;
}
else
{
txtTripNo.Visible = false;
txtTripNo2.Visible = true;
}
}

You can do the following:
private void tabControl_SelectedIndexChanged(...)
{
int index = tabControl.SelectedIndex;
if (index == 0) HideTextBoxes(false);
else HideTextBoxes(true);
}
private void HideTextBoxes(bool someSelector)
{
txtTripNo.Visible = someSelector;
txtTripNo2.Visible = !someSelector;
}

Better to use event Selected
. It passes the actual tab, which is selected in the parameter TabControlEventArgs
:
private void tabControl1_Selected(object sender, TabControlEventArgs e) {
if (e.TabPage == tpExpenseReport) {
txtTripNo.Visible = true;
txtTripNo2.Visible = false;
} else if (e.TabPage == tpExpenseReview) {
txtTripNo.Visible = false;
txtTripNo2.Visible = true;
}
}
