[英]Format dynamically created Radio buttons in Columns in c#
我正在以編程方式為數組/列表中的每個元素創建單選按鈕,並將它們放置在Windows窗體中。
現在,每個新的單選按鈕都位於上一個按鈕的下方。 如何在例如4/5單選按鈕之后設法開始新的一列? 新列應出現在以前的單選按鈕的右側。
到目前為止,這是我的代碼:
for (int i = 0; i < startShapes.Count; i++)
{
RadioButton rdb = new RadioButton();
rdb.Text = startShapes.Values.ElementAt(i).Equals("") ? startShapes.Keys.ElementAt(i) : startShapes.Values.ElementAt(i);
rdb.Size = new Size(100, 30);
this.Controls.Add(rdb);
rdb.Location = new Point(45, 70 + 35 * i);
rdb.CheckedChanged += (s, ee) =>
{
var r = s as RadioButton;
if (r.Checked)
this.selectedString = r.Text;
};
}
如何使用TableLayoutPanel?
Dictionary<string, string> startShapes = new Dictionary<string, string>();
for(int i=0;i<20;i++)
startShapes.Add("Shape " +i, "Shape " +i);
int row = 0;
int col = 0;
tableLayoutPanel1.RowStyles.Clear();
tableLayoutPanel1.ColumnStyles.Clear();
tableLayoutPanel1.ColumnStyles.Add(new ColumnStyle(SizeType.AutoSize));
tableLayoutPanel1.RowCount= 0;
tableLayoutPanel1.ColumnCount = 1;
foreach (var kvp in startShapes)
{
tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.AutoSize));
tableLayoutPanel1.RowCount++;
RadioButton rdb = new RadioButton();
rdb.Text = string.IsNullOrEmpty(kvp.Value) ? kvp.Key : kvp.Value;
rdb.Size = new Size(100, 30);
rdb.CheckedChanged += (s, ee) =>
{
var r = s as RadioButton;
if (r.Checked)
this.selectedString = r.Text;
};
tableLayoutPanel1.Controls.Add(rdb, col, row);
row++;
if (row == 5)
{
col++;
row = 0;
tableLayoutPanel1.ColumnStyles.Add(new ColumnStyle(SizeType.AutoSize));
tableLayoutPanel1.ColumnCount++;
}
}
如果您真的需要解決方案:
int left = 45;
int idx = 0;
for (int i = 0; i < startShapes.Count; i++)
{
RadioButton rdb = new RadioButton();
rdb.Text = startShapes.Values.ElementAt(i).Equals("") ? startShapes.Keys.ElementAt(i) : startShapes.Values.ElementAt(i);
rdb.Size = new Size(100, 30);
this.Controls.Add(rdb);
rdb.Location = new Point(left, 70 + 35 * idx++);
if (idx == 5)
{
idx = 0; // reset row
left += rdb.Width + 5; // move to next column
}
rdb.CheckedChanged += (s, ee) =>
{
var r = s as RadioButton;
if (r.Checked)
this.selectedString = r.Text;
};
}
