使用 OnRowCreated="GridView1_RowCreated" ，在Row create再指定要隱藏。
.aspx
.aspx.cs
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
//隱藏標題列中某特定欄位及該隱藏特定欄位整列
//法一
GridView1.Columns[2].Visible = false;
//法二
foreach (DataControlField col in GridView1.Columns)
{
if (col.HeaderText == "標題文字3")
{
col.Visible = false;
}
}
//法三(using System.Linq;)
((DataControlField)GridView1.Columns
.Cast
.Where(fld => fld.HeaderText == "標題文字3")
.SingleOrDefault()).Visible = false;
}
隱藏標題列中某特定欄位
使用 OnRowDataBound="GridView1_RowDataBound"，資料都好了，再隱藏欄位。
.aspx.cs
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
//隱藏標題列中某特定欄位
//法一
e.Row.Cells[3].Visible = false;
//法二
foreach (TableCell col in e.Row.Cells)
{
if ((((System.Web.UI.WebControls.DataControlFieldCell)(col)).ContainingField).HeaderText == "標題文字4")
{
col.Visible = false;
}
}
//法三
foreach (DataControlFieldCell col in e.Row.Cells)
{
if ((col.ContainingField).HeaderText == "標題文字4")
{
col.Visible = false;
}
}
//法四(using System.Linq;)
e.Row.Cells.Cast
.Where(c => c.Text == "標題文字4")
.ToList()
.ForEach(col => col.Visible = false);
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
}
}
Study:
GridView 的 OnRowDataBound="GridView1_RowDataBound" 及OnRowCreated="GridView1_RowCreated" 的差異。
