[英]Selecting Tab on TabControl using listbox selected Index
I am currently using a tabControl and a listbox independantly of each other. 我目前彼此独立地使用tabControl和列表框。
The tab control has 5 pages on it. 选项卡控件上有5页。 The Listbox has the list of the 5 page titles. 列表框包含5个页面标题的列表。
Edit: I am essentially trying to set the select page of the FundNavigator to be the same as the one selected in the Listbox. 编辑:我实际上是试图将FundNavigator的选择页面设置为与列表框中选择的页面相同。 So if item number 3 in the list box is selected then I want tab number 3 to be displayed as the selected page. 因此,如果选择了列表框中的项目编号3,那么我希望将标签编号3显示为所选页面。
I want to get it so when you select one of the page titles in the ListBox, it will switch to that tab in the TabControl. 我想要得到它,因此当您在ListBox中选择页面标题之一时,它将切换到TabControl中的该选项卡。 I had tried a couple of way, this felt the closest: 我尝试了几种方法,这感觉最接近:
public void LoadMatchingTab()
{
listIndex = ListBox1.SelectedIndex;
FundNavigator.SelectedIndex = FundNavigator.Pages.IndexOf(listIndex);
}
private void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
LoadMatchingTab();
}
With this I am gettinf an ArgumentOutOfRangeException
though andit says 这样我就得到了ArgumentOutOfRangeException
尽管它说
"index out of range. Parameter Name: value" “索引超出范围。参数名称:值”
Could somebody help me fix this problem? 有人可以帮我解决这个问题吗?
FundNavigator.SelectedIndex = ListBox1.SelectedIndex
?
