ListView 选择多项目返回的之前的那项

 

当ListView多选时返回第一次选中的项索引

正确

定义一个变量

=-1 表示第一次没选任何一项

private int FirstSelectedIndex =-1;

 

 

更新FirstSelectedIndex 的值一定要放在Mouse_Click

放在 listView1_SelectedIndexChanged或listView1_ItemSelectionChanged无效

private void listView1_MouseClick(object sender, MouseEventArgs e)         {             int count = listView1.SelectedItems.Count;             if (count > 0)             {                 int Index = listView1.SelectedItems[0].Index;                 if (count == 1)                     FirstSelectedIndex = Index;             } }

       

高亮选中第一次选择的项

Form1_Click

private void Form1_Click(object sender, EventArgs e)         {             if (listView1.Items.Count > 0)             {                 if (FirstSelectedIndex != -1)                 {                     //RUN                     listView1.MultiSelect = false;                     listView1.Focus();                     Text = listView1.Items[FirstSelectedIndex].Text;                     listView1.Items[FirstSelectedIndex].Selected = true;                     listView1.MultiSelect = true;                 }                 if ((FirstSelectedIndex == -1) && (listView1.SelectedItems.Count > 0))                 {                     //RUN                     FirstSelectedIndex = 0;                     listView1.MultiSelect = false;                     listView1.Focus();                     Text = listView1.Items[FirstSelectedIndex].Text;                     listView1.Items[FirstSelectedIndex].Selected = true;                     listView1.MultiSelect = true;                 }             } }
