C# 将按钮与回车键关联
我在C#4.0中得到了一个WinForm项目 我想在用户单击按钮时输入,然后调用此按钮的onclick事件 我的代码:C# 将按钮与回车键关联,c#,button,enter,C#,Button,Enter,我在C#4.0中得到了一个WinForm项目 我想在用户单击按钮时输入,然后调用此按钮的onclick事件 我的代码: public XtraForm_Main() { InitializeComponent(); ... this.AcceptButton = (Button)this.Controls["button_Valider"]; } private void Main_Load(object sender, Event
public XtraForm_Main()
{
InitializeComponent();
...
this.AcceptButton = (Button)this.Controls["button_Valider"];
}
private void Main_Load(object sender, EventArgs e)
{
this.AcceptButton = (Button)this.Controls["button_Valider"];
}
private void button_Valider_Click(object sender, EventArgs e)
{
try
{
using (var connectionWrapper = new Connexion())
{
var connectedConnection = connectionWrapper.GetConnected();
string SqlSyntax = "SELECT * FROM ORDRE WHERE REF_EXPED = @REFERENCE";
SqlCommand comm_InsUpt = new SqlCommand(SqlSyntax, connectionWrapper.conn);
comm_InsUpt.Parameters.AddWithValue("@REFERENCE", textEdit_ref.Text);
SqlDataAdapter adapt_SelectAll = new SqlDataAdapter();
adapt_SelectAll.SelectCommand = comm_InsUpt;
DataSet dSet_SelectAll = new DataSet();
adapt_SelectAll.Fill(dSet_SelectAll, "BON_ETIKET");
var xtraReport_Pricipal = new Zebra_Web();
xtraReport_Pricipal.Parameters["Count_Ordre"].Value = 1;
xtraReport_Pricipal.Parameters["IdPacket"].Value = 1;
xtraReport_Pricipal.DataSource = dSet_SelectAll;
xtraReport_Pricipal.DataMember = dSet_SelectAll.Tables[0].TableName;
xtraReport_Pricipal.CreateDocument();
xtraReport_Pricipal.PrintingSystem.ShowMarginsWarning = false;
xtraReport_Pricipal.PrintingSystem.ContinuousPageNumbering = true;
//xtraReport_Pricipal.ShowPreviewDialog();
xtraReport_Pricipal.Print(Properties.Settings.Default.Zebra);
dSet_SelectAll.Dispose();
adapt_SelectAll.Dispose();
}
}
catch (Exception excThrown)
{
throw new Exception(excThrown.Message, excThrown);
}
}
我试着说:
this.AcceptButton = (Button)this.Controls["button_Valider"];
在构造函数中,从事件加载,但仍不工作。
当用户单击按钮时,不会发生任何事情。我必须用鼠标点击它。您需要将表单的
KeyPreview
属性设置为True
。
然后编写一个KeyDown
事件来处理Enter
Key onForm
详情如下:
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
button_Valider_Click(sender,e);
}
}
我想没有必要再打电话了。那就删除这行代码吧。然后单击按钮。单击时应触发单击事件。要在用户按Windows窗体右侧的Enter键时调用button_Valider_click()函数吗?请尝试将其从主加载事件中删除。发生了什么?我猜@Sudhakar是正确的,他希望使用键盘输入键参考此链接,它应该可以解决您的问题:
