如何動態添加DataGridView到TabPage

Question

我有一個TabControl。 我動態地想要添加動態添加DataGridView的TabPages。 我可以動態添加tabPages，但是當我將DataGridView添加到動態tabPage時，沒有任何顯示。 感謝可以提供的任何幫助。

這是代碼。

                    myTabPage.SuspendLayout();
                    tabControlNonQueued.TabPages.Add(myTabPage);
                    loadDataGridToTab(dataTable, myTabPage);
    private void loadDataGridToTab(DataTable dt, TabPage tab)
    {
        DataGridView grid = new DataGridView();
        tab.Controls.Add(grid);
        tab.Refresh();
        grid.Visible = true;
        System.Windows.Forms.DataGridViewCellStyle dataGridViewCellStyle = new System.Windows.Forms.DataGridViewCellStyle();
        grid.AllowUserToAddRows = false;
        grid.AllowUserToDeleteRows = false;
        grid.AutoSizeColumnsMode = System.Windows.Forms.DataGridViewAutoSizeColumnsMode.Fill;
        grid.ColumnHeadersDefaultCellStyle = dataGridViewCellStyle;
        grid.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
        dataGridViewCellStyle.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleLeft;
        dataGridViewCellStyle.BackColor = System.Drawing.SystemColors.Control;
        dataGridViewCellStyle.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
        dataGridViewCellStyle.ForeColor = System.Drawing.SystemColors.WindowText;
        dataGridViewCellStyle.SelectionBackColor = System.Drawing.SystemColors.Highlight;
        dataGridViewCellStyle.SelectionForeColor = System.Drawing.SystemColors.HighlightText;
        dataGridViewCellStyle.WrapMode = System.Windows.Forms.DataGridViewTriState.True;
        grid.ColumnHeadersDefaultCellStyle = dataGridViewCellStyle;
        grid.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
        //grid.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
        //this.cbDG});


        hideDGColumn(grid, "Counter");
        SetFontAndColors(grid);
        lockDataGrid(grid);
        BindingSource source = new BindingSource();
        source.DataSource = dt;
        grid.Dock = DockStyle.Fill;
        grid.DataSource = source;

    }

謝謝

您是否嘗試過將tab.Controls.Add（grid）語句移動到網格配置后？

另外，我注意到你正在使用“SuspendLayout（）”來允許無閃爍更新。 你還記得重新打開布局嗎？

例如，這個：

myTabPage.SuspendLayout();
tabControlNonQueued.TabPages.Add(myTabPage);
DataGridView grid = new DataGridView();

// ... grid configuration and setup here ...

tab.Controls.Add(grid);
myTabPage.ResumeLayout();
tab.Refresh();
