最近用到checklistbox控件,在使用其过程中,花了较多的时间,这里我收集了其相关的代码段,希望对大家有所帮助。
//1.添加项checkedListBox1.Items.Add("蓝色"); checkedListBox1.Items.Add("红色"); checkedListBox1.Items.Add("黄色"); //2.判断第i项是否选中,选中为true,否则为falseif(checkedListBox1.GetItemChecked(i)){ return true;} else{ return false; } //3.设置第i项是否选中checkedListBox1.SetItemChecked(i, true); //true改为false为没有选中。 //4.设置全选 //添加一个名为select_all的checkbox控件,由其控制checkedListBox是全选还是全不选。private void select_all_CheckedChanged(object sender, EventArgs e) { if(select_all.Checked) { for (int j = 0; j < checkedListBox1.Items.Count; j++) checkedListBox1.SetItemChecked(j, true); }else {for (int j =0; j < checkedListBox1.Items.Count; j++) checkedListBox1.SetItemChecked(j, false);}} //5.得到全部选中的值 ,并将选中的项的文本组合成为一个字符串。string strCollected = string.Empty;for (int i = 0; i < checkedListBox1.Items.Count; i++){ if (checkedListBox1.GetItemChecked(i)) { if (strCollected == string.Empty) { strCollected = checkedListBox1.GetItemText(checkedListBox1.Items[i]); } else { strCollected = strCollected + "/" + checkedListBox1.GetItemText(checkedListBox1.Items[i]); } }} //6.设置CheckedListBox中第i项的Checked状态checkedListBox1.SetItemCheckState(i, CheckState.Checked); //7.private void checkBoxAll_CheckedChanged(object sender, EventArgs e) { if (checkBoxAll.Checked) { //被选择了则将CheckedListBox中的所有条目都变为Checked状态 for (int i = 0; i < checkedListBoxLayerControl.Items.Count; i++) { checkedListBoxLayerControl.SetItemCheckState(i, CheckState.Checked); } }else { //否则变成Unchecked状态 for (int i = 0;i < checkedListBoxLayerControl.Items.Count; i++) {checkedListBoxLayerControl.SetItemCheckState(i, CheckState.Unchecked); } }} //8.checkedListBox 单选设置(代码实现)private void chkl_ItemAuditing_ItemCheck(object sender, ItemCheckEventArgs e){ if (chkl_ItemAuditing.CheckedItems.Count > 0) { for (int i = 0; i < chkl_ItemAuditing.Items.Count; i++) {if (i != e.Index) { this.chkl_ItemAuditing.SetItemCheckState(i, System.Windows.Forms.CheckState.Unchecked); } } } } //9.checkedListBox1显示一个数据库中关键字对应的所有记录for (int i = 0; i < table.Rows.Count; i++) { string name = table.Rows["myname"].ToString(); string paw = table.Rows["mypaw"].ToString(); checkedListBox1.Items.Add(name + paw); } //10.for(i=0;icheckedListBox2for (int i = 0; i < checkedListBox1.CheckedItems.Count; i++) { checkedListBox2.Items.Add(this.checkedListBox1.CheckedItems);//remove是除去一个具体的值,不是index,注意了 this.checkedListBox1.Items.Remove( this.checkedListBox1.CheckedItems); }
