“垫子”列标题上的宽度？ [英] "Cushion" width on a column header?

问题描述

我有一个小循环功能，可根据列标题文本的宽度来调整列的大小：

I have a little loop function that resizes the columns based on the width of the text of the Column Header:

var columns = VView.gridViewCblID.Columns;

foreach (DataGridViewColumn clm in columns)
{
    VView.lblDummy.Text = clm.HeaderText;
    if (clm.Width > VView.lblDummy.Width && clm.Width <= 100)
    {
        clm.Width = VView.lblDummy.Width;
    }
}

但是，由于垫子是自动应用于列HeaderText的左侧，列将呈现束缚外观：

However, due to a "cushion" that is automatically applied to the left of the Column HeaderText, the columns get a "bunched" appearance:

该缓冲垫的实际宽度是多少，因此我可以将其应用于该方法？即

What is the actual width of that cushion, so I can apply it to the method? I.e.

clm.Width = VView.lblDummy.Width + (cushion *2);

推荐答案

可以使用 AutoSizeColumnsMode 为您完成工作，然后将调整大小模式重新设置为手动。例如

It's possible to use AutoSizeColumnsMode to do the work for you, and then set the resize mode back to manual. E.g.

DataGridView dgv = new DataGridView() { Dock = DockStyle.Fill };
dgv.Columns.Add("Cable Number", "Cable Number");
dgv.Columns.Add("Type", "Type");
dgv.Columns.Add("Length", "Length");

dgv.Columns["Type"].AutoSizeMode = DataGridViewAutoSizeColumnMode.ColumnHeader;

Form f = new Form();
f.Controls.Add(dgv);
dgv.HandleCreated += delegate {
    dgv.BeginInvoke((Action) delegate {
        var c = dgv.Columns["Type"];
        int w = c.Width;
        c.Width = w; // set current width, otherwise DGV reverts to previous 100 width
        c.AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
    });
};
