如果我做的ShowDialog（），并传递   父母它的工作原理......但我真的不   要显示它作为一个对话框。

这是正确的，因为ShowDialog的将设置frm.Parent == nvShowDeals.Parent
由于使用.Show（），然后frm.Parent == NULL从而FormStartPosition.CenterParent被忽略。

因此​​，要完成这个功能我会做如下修改：

 公共DealsForm（）
{
    的InitializeComponent（）;
    //this.StartPosition = FormStartPosition.CenterParent;
}

// DealsForm_Load事件
私人无效DealsForm_Load（对象发件人，EventArgs的）
{
    this.Location = this.Owner.Location; //新的code
}
 

在这里，我将做如下修改：

 私人无效nvShowDeals_LinkClicked（对象发件人，LinkLabelLinkClickedEventArgs E）
{
    DealsForm FRM =新DealsForm（）;

    frm.DataSource = this.Deals;
    frm.StartPosition = FormStartPosition.Manual; //新的code
    frm.Show（本）;
}
 

Is there a way to set the StartPosition of a Windows Forms form using code? It seems whatever I try results in the StartPostion being the default.

Here is what I am doing in the form to display:

    public DealsForm()
    {
        InitializeComponent();
        this.StartPosition = FormStartPosition.CenterParent;
    }

Here is what I am doing to display the form:

    private void nvShowDeals_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
    {
        DealsForm frm = new DealsForm();

        frm.DataSource = this.Deals;

        frm.Show(this);
    }

I have tried putting the following in each of the above methods, to no avail:

this.StartPosition = FormStartPosition.CenterParent;

If I set it via the Property Editor ... it works perfectly, but I would really like to do it via code.

Should be a no-brainer ... but for the life of me I can't seem to figure it out ... maybe I need more caffeine.

Update:

If I do a ShowDialog() and pass the parent it works ... but I really don't want to show it as a Dialog.

If I do a ShowDialog() and pass the parent it works ... but I really don't want to show it as a Dialog.

That is correct since ShowDialog would set frm.Parent == nvShowDeals.Parent
Since you are using .Show() then frm.Parent == null thus FormStartPosition.CenterParent is ignored.

So to accomplish this function I would make the following changes:

public DealsForm()
{
    InitializeComponent();
    //this.StartPosition = FormStartPosition.CenterParent;
}

//DealsForm_Load Event
private void DealsForm_Load(object sender, EventArgs e)
{
    this.Location = this.Owner.Location;  //NEW CODE
}

And Here I would make the following changes:

private void nvShowDeals_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    DealsForm frm = new DealsForm();

    frm.DataSource = this.Deals;
    frm.StartPosition = FormStartPosition.Manual; //NEW CODE
    frm.Show(this);
}
