C# DataGridViewCheckboxCell usage

如何获取DataGridViewCheckBoxCell的值

方法1，需要给DATAGRIDVIEW控件添加事件CellContentClick，这里我将CHECKBOX放在数据列的第一个所以我判断参数中COLUMNINDEX是否为0，同时需要注意的是使用属性EditedFormattedValue，不能使用Value值，因为Value值是旧值。

private void dgvABList_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex == 0 && e.RowIndex != -1)
{
bool bSelect = Convert.ToBoolean(dgvABList[e.ColumnIndex, e.RowIndex].EditedFormattedValue);
string id = dgvABList[1, e.RowIndex].Value.ToString();
if (bSelect == true && m_delABs.Contains(id) == false)
{
m_delABs.Add(id);
}
if (bSelect == false && m_delABs.Contains(id) == true)
{
m_delABs.Remove(id);
}
}
}

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

方法2:， 就是通过遍历整个DATAGRIDVIEW中的所有行来获取所有选上的数据，

List<int> selected = new List<int>();
foreach (DataGridViewRow row in dgvABList.Rows)
{
if (Convert.ToBoolean(row.Cells[0].Value) == true)
{
selected.Add(row.Index);
}
}

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

关键都是使用了Converter的ToBoolean函数来将object的true或者false转换成bool型。
