我有一个绑定到datagridview的列表。我希望第一列是固定大小。数据绑定到dataGridView,我似乎找不到找到访问单个列属性的方法。如果尝试使用myDatagridview.colums [0],我会得到一个超出范围的索引,因为它说列数为0。
private DataGridView setUpDataGrid(List<NVRlineVal> _NVRData)
{
//setup dataGridView
DataGridView NVRDataGridView = new System.Windows.Forms.DataGridView();
NVRDataGridView.ColumnHeadersHeightSizeMode =
System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
NVRDataGridView.Dock = System.Windows.Forms.DockStyle.Fill;
NVRDataGridView.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;
NVRDataGridView.Name = "NVRDataGridView" + nvrIndex;
NVRDataGridView.RowHeadersWidthSizeMode =
System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode.AutoSizeToDisplayedHeaders;
NVRDataGridView.TabIndex = 0;
NVRDataGridView.DataSource = _NVRData;
//var clmn = NVRDataGridView.Columns[0];
return NVRDataGridView;
}
关于如何仅对其中一列具有固定列宽的任何想法,其余的将自动调整大小?

我做类似的事情,但格式。
问题在于设置数据源后未绘制网格-您需要在DataBindingComplete
事件中进行更改。
这是一些片段...
(来自https://minisqlquery.svn.codeplex.com/svn/trunk/MiniSqlQuery/QueryForm.cs)
-网格清晰度:
this.gridResults1.AllowUserToAddRows = false;
this.gridResults1.AllowUserToDeleteRows = false;
this.gridResults1.AutoSizeColumnsMode = System.Windows.Forms.DataGridViewAutoSizeColumnsMode.ColumnHeader;
this.gridResults1.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
this.gridResults1.Dock = System.Windows.Forms.DockStyle.Fill;
this.gridResults1.Location = new System.Drawing.Point(3, 3);
this.gridResults1.Name = "gridResults1";
this.gridResults1.ReadOnly = true;
this.gridResults1.Size = new System.Drawing.Size(1023, 242);
this.gridResults1.TabIndex = 0;
-稍后订阅
DataBindingComplete
事件:grid.DataBindingComplete += GridDataBindingComplete;
-处理事件(这里我正在修改格式,但是您尝试更改宽度):
private void GridDataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
DataGridView grid = sender as DataGridView;
if (grid == null)
{
return;
}
DataTable dt = grid.DataSource as DataTable;
if (dt == null)
{
return;
}
string nullText = _settings.NullText;
string dateTimeFormat = _settings.DateTimeFormat;
for (int i = 0; i < dt.Columns.Count; i++)
{
if (dt.Columns[i].DataType == typeof (DateTime))
{
DataGridViewCellStyle dateCellStyle = new DataGridViewCellStyle();
dateCellStyle.NullValue = nullText;
dateCellStyle.Format = dateTimeFormat;
grid.Columns[i].DefaultCellStyle = dateCellStyle;
}
}
}
