vb.net中如何實現(xiàn)checkbox的全選?

參考方法如下：

站在用戶的角度思考問題，與客戶深入溝通，找到張家川回族自治網(wǎng)站設(shè)計與張家川回族自治網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗，讓設(shè)計與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個性化、用戶體驗好的作品，建站類型包括：成都做網(wǎng)站、成都網(wǎng)站設(shè)計、企業(yè)官網(wǎng)、英文網(wǎng)站、手機端網(wǎng)站、網(wǎng)站推廣、域名注冊、網(wǎng)站空間、企業(yè)郵箱。業(yè)務(wù)覆蓋張家川回族自治地區(qū)。

$("input[type='checkbox']").attr("checked",true);

用js這樣就行了，如果用C#，參考如下：

foreach (Control item in this.Controls)

{

if (item is CheckBox)

{

CheckBox box = (CheckBox)item;

box.Checked = true;

}

}

vb.net中控件ListBox的多項選擇與輸出！

Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged

MessageBox.Show(ListBox1.SelectedItem.ToString)

End Sub

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

For i As Integer = 0 To 10

ListBox1.Items.Add(i.ToString)

Next

End Sub

'''''''選擇多項

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

For i As Integer = 0 To 10

ListBox1.Items.Add(i.ToString)

Next

ListBox1.SelectionMode = SelectionMode.MultiSimple

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim item

For Each item In ListBox1.SelectedItems

MessageBox.Show(item.ToString)

Next

End Sub

vb.net textbox1.text 鼠標一點 全部選擇

Private?Sub?TextBox1_Click(sender?As?Object,?e?As?EventArgs)?Handles?TextBox1.Click

TextBox1.SelectAll()

TextBox1.ForeColor?=?Color.Blue

End?Sub

如果不想每次都這樣的話，就加一個if判斷TextBox1.ForeColor 是否是Color.Blue就可以了

vb.net textbox1.selectAll()

SelectAll其實已經(jīng)把所有文本選上了，只不過沒有高亮而已，但是你可以自己模擬一個選擇高亮：

r.SelectAll()

r.SelectionColor = System.Drawing.Color.White ' 文字色

r.SelectionBackColor = System.Drawing.Color.Navy ' 背景色
