问题描述
非常快的问题 - 我不能正确地看到它，但没有任何理由的ASP按钮btnEdit仍可见在GridView？上的RowDataBound（用于测试）我只是想用这个计划将其隐藏后来把if语句周围。
Very quick question - I must not be seeing it properly, but is there any reason why the ASP button "btnEdit" is still visible in the gridview? On RowDatabound (for testing) I'm just trying to hide it with the plan to put an if statement around it later.
code后面（的RowDataBound）
protected void gvEditUser_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Button btnEdit = (Button)e.Row.FindControl("btnEdit");
btnEdit.Visible = false;
if (e.Row.RowState != null)
{
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{
CheckBox cbAdmin = (CheckBox)e.Row.FindControl("cbAdmin");
DataRowView dr = e.Row.DataItem as DataRowView;
if (Convert.ToBoolean(dr["admin"] = true))
{
cbAdmin.Checked = true;
}
else
{
cbAdmin.Checked = false;
}
}
}
}
}
