datagridview控件如何同时选多条记录
datagridview控件如何同时选多条记录呢, 我做一个窗体FORM1 ,和一个窗体FORM2 ,每个窗体都有datagridview控件,我想在FORM1上的datagridview上同时选择5条记录,复制到FORM2控件上,这个例子有没有, 我想左键呢是选择,右键是放弃所有的选择,高人们,帮我看一下这个代码如何写,非常感谢. 冬天太冷,多穿衣服.

让同时选多条记录：设置dataGridView1.MultiSelect = true;
复制多行：
List<model> modelList = new List<model>(); //存储复制的model(行)
void toolStripMenuItemCopy_Click(object sender, EventArgs e)
{
modelList.Clear();
if (dataGridView1.SelectedRows.Count > 0)
{
toolStripMenuItemPaste.Enabled = true;
toolStripMenuItemCopyEnabled = false;
for (int i = 0; i < dataGridView1.SelectedRows.Count; i++)
{
model modelTemp = new model();
tool.gridviewtomodel.Datagridview2Model(dataGridView1, modelTemp, Convert.ToInt32(dataGridView1.SelectedRows[i].Index));
modelTemp.字段= this.字段;
modelList.Add(modelTemp);
}
//设置此行的状态
foreach (DataGridViewRow dgvRow in dataGridView1.SelectedRows)
{ //复制时不用移除，剪切需要移除行
dataGridView1.Rows.Remove(dgvRow);
}
}
}
//黏贴
void toolStripMenuItemPaste_Click(object sender, EventArgs e)
{
toolStripMenuItemCopy.Enabled = true;
toolStripMenuItemPaste.Enabled = false;
foreach (model modelTemp in modelList)
{
modelTemp.字段=字段;
ws_model.Update(modelTemp); //做更新操作
}
modelList.Clear();
}
[解决办法]
1、dataGridView1.MultiSelect = true;
2、在后台遍历并获取选中的多行，作为一个数据集传到form2中，作为form2的数据源即可
[解决办法]
- C# code
//下面的代码 左键点击增加选择 右键取消选择，不知道有没有更好的办法private List<int> selectedRowsIndex = new List<int>();//用来存放选中的index delegate void SetSelectState(bool deSelect, int rowIndex); void RefreshTheSelectedStates(bool deSelect, int rowIndex) { try { foreach (int idx in selectedRowsIndex) { dataGridView2.Rows[idx].Selected = true; } if (deSelect) { dataGridView2.Rows[rowIndex].Selected = false; } } finally { dataGridView1.Refresh(); } } private void dataGridView2_MouseDown(object sender, MouseEventArgs e) { DataGridView.HitTestInfo testInfo = dataGridView2.HitTest(e.X, e.Y); int rowIdx = testInfo.RowIndex; switch(e.Button) { case MouseButtons.Left: if (rowIdx >= 0) { if (!selectedRowsIndex.Contains(rowIdx)) selectedRowsIndex.Add(rowIdx); dataGridView2.BeginInvoke(new SetSelectState(RefreshTheSelectedStates), false, 0); } break; case MouseButtons.Right: if (rowIdx >= 0) { if (selectedRowsIndex.Contains(rowIdx)) selectedRowsIndex.Remove(rowIdx); dataGridView2.BeginInvoke(new SetSelectState(RefreshTheSelectedStates), true, rowIdx); } break; } }
