datagridview 合并单元格问题
在这里看了些资料，
http://www.cnblogs.com/peterzb/archive/2009/05/29/1491891.html
使用rowmergeview做单元格合并和二维表头，
前两列都可以，第三列数字列却合并不了，试了好久，有没有谁用过这个控件？指条明路啊！
下面是代码
rowmergeview 合并单元格 无效
private void dgvColumnsBindC()
{
this.rmvItem.EnableHeadersVisualStyles = false;
this.rmvItem.AutoGenerateColumns = false;
this.rmvItem.Columns.Clear();//列头清空下
Dictionary<string, string> dataText = new Dictionary<string, string>();
dataText.Add("ItemName", "考核类型");
dataText.Add("IName", "考核项目");
dataText.Add("Weights", "权重");
dataText.Add("Description", "考核明细");
dataText.Add("Scores", "分值");
foreach (KeyValuePair<string, string> kvp in dataText)
{
DataGridViewTextBoxColumn dgvc = new DataGridViewTextBoxColumn();
dgvc.DataPropertyName = kvp.Key;
dgvc.HeaderText = kvp.Value;
dgvc.Name = kvp.Key;
dgvc.ReadOnly = true;
if (kvp.Value == "权重" || kvp.Value == "分值") dgvc.DefaultCellStyle.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleRight;
if (kvp.Value == "考核类型" || kvp.Value == "考核项目") dgvc.DefaultCellStyle.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleCenter;
if (kvp.Value == "考核明细") dgvc.DefaultCellStyle.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleLeft;
dgvc.HeaderCell.Style.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleCenter;//居中
dgvc.AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
if (kvp.Value == "权重" || kvp.Value == "分值") dgvc.Width = 80;
if (kvp.Value == "考核类型" || kvp.Value == "考核项目") dgvc.Width = 150;
if (kvp.Value == "考核明细" ) dgvc.Width = 430;
this.rmvItem.Columns.Add(dgvc);
}
this.rmvItem.MergeColumnNames.Add("ItemName");
this.rmvItem.MergeColumnNames.Add("IName");
this.rmvItem.MergeColumnNames.Add("Weights");
}
