gridview隐藏了列后，要在什么事件中取得模板列中的控件值？
<asp:TemplateField HeaderText= "小图片 " SortExpression= "ImgUrlSml ">
<EditItemTemplate>
<asp:Label ID= "Label2 " runat= "server " Text= ' <%# Eval( "ImgUrlSml ") %> '> </asp:Label>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID= "Label1 " runat= "server " Text= ' <%# Bind( "ImgUrlSml ") %> '> </asp:Label>
</ItemTemplate>
</asp:TemplateField>

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Cells(8).Visible = False
End If
End Sub
问题一：怎样隐藏HeaderText？
问题二：如何取得Label1的值？

问题一：怎样隐藏HeaderText？
＝＝＝＝＝＝
你执行了
e.Row.Cells(8).Visible = False
还可以看到 HeaderText ？？？
问题二：如何取得Label1的值？
＝＝＝＝＝＝
你准备在哪里获取？
// 外部 Button
protected void Button1_Click(object sender, EventArgs e)
{
int cellIndex = 0; // 单元格索引
foreach (GridViewRow row in GridView1.Rows) {
CheckBox chk = row.FindControl( "MyCheckBoxID ") as CheckBox;
Label lbl = (Label)row.FindControl( "MyLabelID ");
// OR
//int cellIndexOfCheckBox = 1; // 表示 CheckBox 所在列索引
//CheckBox chk = row.Cells[cellIndexOfCheckBox].Controls[0] as CheckBox;
if (chk.Checked) {
Label1.Text = row.Cells[cellIndex].Text;
}
}
}
// RowDataBound 事件
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
CheckBox chk = e.Row.FindControl( "MyCheckBoxID ") as CheckBox;
Label lbl = (Label)e.Row.FindControl( "MyLabelID ");
}
// RowCommand 事件
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
Control cmdSource = e.CommandSource as Control;
GridViewRow row = cmdSource.NamingContainer as GridViewRow;
int rowIndex = row.RowIndex;
int cellIndex = 0;
Label1.Text = row.Cells[cellIndex].Text;
CheckBox chk = row.FindControl( "MyCheckBoxID ") as CheckBox;
Label lbl = (Label)row.FindControl( "MyLabelID ");
}
[解决办法]
GridView1.Columns[8].Visible=false;
