怎样遍历Form中所有自动生成的CheckedListBox(急)
如题:
怎样遍历Form中所有自动生成的CheckedListBox
遍历想查看每个CheckedListBox有多少被选中,多少没选!
请各位帮忙 开解
[解决办法]
foreach (CheckBox cb in Form.Controls)
{
if (cb.Checked)
{
selectTypeCount++;
}
}
if (selectTypeCount == 0)
{
error.SetError(groupBox1, "请至少选择一种图片类型 ");
}
else
{
error.SetError(groupBox1, " ");
}
本人的程序代码。我用的是CheckBox,你用的是CheckedListBox，我想这个不难改成你希望的代码。
[解决办法]
我以前是这样解决的，改变控件的外观，稍加修改应该适用于你的要求，不知道有没有更好的办法。
foreach (Control c in this.Controls)
{
string s = c.GetType().ToString();
switch (s)
{
case "System.Windows.Forms.Button ":
{
Button b = (Button)c;
if (b.FlatStyle == FlatStyle.Flat)
{
b.FlatStyle = FlatStyle.Standard;
}
else
{
b.FlatStyle = FlatStyle.Flat;
}
break;
}
case "System.Windows.Forms.TextBox ":
{
TextBox t = (TextBox)c;
if (t.BorderStyle == BorderStyle.FixedSingle)
{
t.BorderStyle = BorderStyle.Fixed3D;
}
else
{
t.BorderStyle = BorderStyle.FixedSingle;
}
break;
}
}
}
