我有一个使用SQL添加供应商的表格
SupplierID
表中有SupplierName
,SupplierProduceType
,SupplierPhone
和Supplier
我的ID,姓名和电话没有问题,但是由于有1-5个选项可供选择,因此产品类型比较困难
如果要检查5个框,我希望文本框显示beef,pork,chicken,lamb,sauce
(用逗号分隔),显然如果只选择了3个,我只希望这3个框显示
当我点击添加供应商按钮时,SQL代码将为:
sql = "INSERT INTO[Supplier](SupplierID, SupplierName, SupplierProduceType, SupplierPhone) Values('" + Convert.ToInt32(SupplierIDTB.Text) + "', '" + SupplierNameTB.Text + "', '" + SupplierProduceTypeTB.Text + "', '" + Convert.ToInt32(SupplierPhoneTB.Text) + "')";
因此,当sql代码从SupplierProduceTypeTB.Text读取时,它将读取“牛肉,猪肉,鸡肉,羊肉,调味料”(如果全部5个都选中),并将其输入到SupplierProduceType列中
到目前为止,我有:
protected void BeefCB_CheckedChanged(object sender, EventArgs e)
{
String input1 = "beef,";
SupplierProduceTypeTB.Text += input1;
}
但这什么都不做!

您只需要在代码中进行一些更改。
尝试以下代码
protected void BeefCB_CheckedChanged(object sender, EventArgs e)
{
SupplierProduceType();
}
protected void PorkCB_CheckedChanged(object sender, EventArgs e)
{
SupplierProduceType();
}
protected void ChickenCB_CheckedChanged(object sender, EventArgs e)
{
SupplierProduceType();
}
protected void LambCB_CheckedChanged(object sender, EventArgs e)
{
SupplierProduceType();
}
protected void SauceCB_CheckedChanged(object sender, EventArgs e)
{
SupplierProduceType();
}
private void SupplierProduceType()
{
string produceType = string.Empty;
if(BeefCB.Checked)
{
produceType = "Beef, ";
}
if(PorkCB_Checked)
{
produceType += "Pork, ";
}
if(ChickenCB_Checked)
{
produceType += "Chicken, ";
}
if(LambCB_Checked)
{
produceType += "Lamb, ";
}
if(SauceCB_Checked)
{
produceType += "Sauce, ";
}
SupplierProduceTypeTB.Text = produceType;
}
+ =不适用于textbox.Text属性。
通过创建函数来尝试使用此函数,并在每个复选框checkchange方法中调用它。

所以我的解决方法是在添加供应商按钮中执行if语句:
if (BeefCB.Checked) {
String input1 = "beef,";
string textboxValue = SupplierProduceTypeTB.Text;
SupplierProduceTypeTB.Text = textboxValue + input1;
}
if (PorkCB.Checked) {
String input1 = "pork,";
string textboxValue = SupplierProduceTypeTB.Text;
SupplierProduceTypeTB.Text = textboxValue + input1;
}
if (ChickenCB.Checked) {
String input1 = "chicken,";
string textboxValue = SupplierProduceTypeTB.Text;
SupplierProduceTypeTB.Text = textboxValue + input1;
}
if (LambCB.Checked) {
String input1 = "lamb,";
string textboxValue = SupplierProduceTypeTB.Text;
SupplierProduceTypeTB.Text = textboxValue + input1;
}
if (SauceCB.Checked) {
String input1 = "sauce";
string textboxValue = SupplierProduceTypeTB.Text;
SupplierProduceTypeTB.Text = textboxValue + input1;
}
