c# – 无法使用ToolStripLayoutStyle.Table在ToolStrip中以编程方式调整ToolStripItem的大小

我想以编程方式用项目填充ToolStrip. toolStrip1.LayoutStyle必须是ToolStripLayoutStyle.Table.但我不能改变项目的宽度,即使我这样做,宽度恢复为默认值.

ToolStripLabel tslCheck = new ToolStripLabel("First Text"),tslSumm = new ToolStripLabel("second Text:"),tslError = new ToolStripLabel("third text:"),tslAccount = new ToolStripLabel("fourth text"),tslProvider = new ToolStripLabel("fifth text");
ToolStripTextBox tbCheck = new ToolStripTextBox(),tbAccount = new ToolStripTextBox(),tbSumm = new ToolStripTextBox(),tbError = new ToolStripTextBox();
TableLayoutSettings tsSettings;

ToolStripComboBox cbProvider = new ToolStripComboBox();       

protected void toolStrip1_Construct()
{
    toolStrip1.LayoutStyle = ToolStripLayoutStyle.Table;            
    tsSettings = toolStrip1.LayoutSettings as TableLayoutSettings;
    tsSettings.RowCount = 2; 
    tsSettings.ColumnCount = 6;

    cbProvider.DropDownStyle = ComboBoxStyle.DropDownList;

    ///adding controls
    toolStrip1.Items.AddRange(new ToolStripItem[]
    {
        tslCheck,tbCheck,tslAccount,tbAccount,tslProvider,cbProvider,//second row
        tslSumm,tbSumm,tslError,tbError
    });

    tbAccount.Width = 1000; //Width is still remains 100
    cbProvider.Width = 500; //Width is still remains 121
}

但是,如果我在VisualDesigner中这样做,一切正常.

解决方法

您必须将AutoSize属性设置为false：

ToolStripComboBox cbProvider = new ToolStripComboBox() { AutoSize = false };
