我有一个主窗体,用于计算并打开和关闭用户创建的项目。
当用户单击 File 下的 Open Project 按钮时,将打开一个名为 Open Project 的表单,如下所示,允许用户加载项目:
现在,我想在单击“确定”后将此表单中的数据传递到主表单中。
我遇到的问题是主窗体已经打开。
对此问题的任何解决方案将不胜感激。
尝试创建Properties
一个Open Project Form
主表格
private void openButton_Click(object sender, EventArgs e)
{
using(var f = new Open_Project_Form())
{
f.ProjectReference = projectRefrencetTextBox.Text;
f.ProjectNo = projectNoTextBox.Text;
f.ShowDialog();
}
}
打开项目表格
public string ProjectReference { get; set; }
public string ProjectNo { get; set; }
private void Open_Project_Form_Load(object sender, EventArgs e)
{
projectRefrenceComboBox.Text = ProjectReference;
projectNoTextBox.Text = ProjectReference;
}
我误解了这个问题。我之前的回答是从MainForm
到OpenProjectForm
这次是从OpenProjectForm
到MainForm
主表格
//Properties for MainForm
public string ProjectReference { get; set; }
public string ProjectNo { get; set; }
private void openButton_Click(object sender, EventArgs e)
{
using(var f = new Open_Project_Form() { Owner = this })
{
f.ShowDialog();
if (f.DialogResult == DialogResult.OK)
{
projectRefrencetTextBox.Text = ProjectReference;
projectNoTextBox.Text = ProjectNo;
}
}
}
打开项目表格:请注意,您有一个okButton
和cancelButton
private void Open_Project_Form_Load(object sender, EventArgs e)
{
okButton.DialogResult = DialogResult.OK;
this.AcceptButton = okButton;
this.CancelButton = cancelButton;
}
现在,在okButton_Click event
private void okButton_Click(object sender, EventArgs e)
{
var f = Owner as MainForm;
if (f == null) return;
f.ProjectReference = projectRefrenceComboBox.Text;
f.ProjectNo = projectNoTextBox.Text;
Close();
}

希望它会帮助你。
可以使用事件吗?创建一个 EventClass 并将值作为事件的结果返回。
在打开的表单类中创建一个事件:
public event EventHandler<ProjectDetailsArgs> ProjectDetailsSubmitted;
public class ProjectDetails: EventArgs
{
public string projectReference{ get; set; }
public string projectNo{get;set;}
//you can add more prop.s here
}
On your Ok button click event add
if (ProjectDetailsSubmitted != null)
{
ProjectDetailsArgs argss = new ProjectDetailsArgs();
argss.projectReference = projectRefrencetTextBox.Text;
argss.projectNo = projectNoTextBox.Text;
ProjectDetailsSubmitted(null, argss);
}
在您的主窗体中为其创建一个处理程序:
childform.ProjectDetailsSubmitted+=new EventHandler<ProjectDetailsArgs>project_detailsSubmitted);
public void project_detailsSubmitted(object sender, ProjectDetailsArgs e)
{
//Do Your work
}
