Question

我想要做的是添加一个由复选框填充并放在网格左侧的列。网格行是从查询绑定的。我有这段代码：

string query = "SELECT TransID, Company, Period, EmpID, Employee FROM Trx"
DataTable tblClaim;
tblClaim = DB.sql.Select(query);
tblClaim.Columns.Add("Process", typeof(bool)); //I want this column placed on the left side of the grid
gcxClaim.ExGridControl.DataSource = tblClaim;

我从该代码得到的是，禁用该复选框并将列放在右侧。当我尝试在tblClaim.Columns.Add("Process", typeof(bool));之前放置tblClaim = DB.sql.Select(query);时，却出错了。我怎样才能做到这一点？感谢。

Answer 1

试试这个，

tblClaim.Columns.Add("Process", typeof(bool)).SetOrdinal(0);

这会将“Process”列的索引设置为0

Answer 2

它的工作原理如下：

string query = "SELECT CAST(1 AS BIT) AS Process, TransID, Company, Period, EmpID, Employee FROM Trx"

tblClaim = DB.sql.Select(query);
gcxClaim.ExGridControl.DataSource = tblClaim;
gcxClaim.ExGridView.OptionsBehavior.Editable = true;
for (int i = 0; i < tblClaim.Columns.Count; i++)
{
    gcxClaim.ExGridView.Columns[i].OptionsColumn.AllowEdit = false;
}
gcxClaim.ExGridView.Columns["Process"].OptionsColumn.AllowEdit = true;

将Checkbox列添加到GridControlEx中
